Computer Infrastructure Management topics:


Computer Infrastructure refers to the various infrastructures such as Computer Hardware, Computer Software, and Networking Accessories a computer environment. The infrastructure should be planned in such a way that it should be adequate and supporting according to the data processing requirement of the environment. Infrastructure includes amenities utilized for the management under computerized environment. The basic infrastructure includes electricity, Network Cabling, Internet Accessing points, human resources having adequate knowledge about the working of the computer, computer hardware devices and peripherals connected to the computer system, computer software, such as system software, application packages and utility software for supporting the data processing system in the environment. The effective management of infrastructure is the essential part of electronic data processing system. The infrastructure should b controlled and effectively applied for attaining required results under data processing system.

Computer Infrastructure Management provides the effective utilization of infrastructure applied in an Electronic Data Processing System. The various advantages of Computer infrastructure management is given below:

1) Better Utilization of Infrastructure resources.

2) Infrastructure resources are shared for getting better results.

3) Computer Infrastructure Management aims at controlling the cost aspect.

4) Computer Infrastructure Management prevents the wastage of energy such as electricity, manpower etc.

5) Planning and Implementation according to the requirement of the environment is done through computer infrastructure management.

Computer Infrastructure Management refers to the entire range of planning, Decision Making, Maintenance and Troubleshooting activities related to Computer Networks, primarily in business organization. One of the most important factors in this domain is ensuring a near total uptime of thee network being handled. For most of the service industries, computers, networks and the Internet are the primary working platforms, and the Computer Infrastructure Management aims to ensure that the development team gets uninterrupted service.

Main Requirements of the Computer Infrastructure Management

Computer Infrastructure management is a difficult task performed on the basis of various requirements of the Computer Environment. Computer Infrastructure Management charts out the entire computer hardware and computer software requirements. A detailed analysis should be carried out regarding the entire layout of the project with the help of appropriate charts and layouts prepared manually. Space is one of the constraints for the implementation of infrastructure facilities. There are some main points to be remembered and required for an effective Computer Infrastructure Management which are given below:

1. The entire requirement of computer hardware and computer software should be estimated.

2. The Network points and connectivity requirements should be analysed.

3. The space availability should be planned carefully.

4. There should be a systematic planning for the expansion activities in the future.

5. Layout and charts should be prepared for better implementation.

6. Nature of work done through computers should be borne in mind for an effective infrastructure management.

7. Project should be analysed and the requirement of the computer hardware and software support required for the project should be designed carefully.

8. Adequate Electrical points and Network points should be estimated.

9. Server Room and UPS Room should be designed carefully.

10. The topology of the Networking should be designed according to the space availability.

An essential part of computer infrastructure management is Networking. But to understand networking, it is important to have an idea about what exactly a network means. A network is a collection of computer and other electronic devices like printers etc., connected together through a common medium like network cabling or wireless technology to a giant global network such as the internet. The network can be used to transmit voice, data and even video between users, who are part of the network.

Network infrastructure includes computers, connectivity mediums like copper wire or fibre optic cable and other devices such as Switches, Routers, Hubs etc. Other devices like the network interface card can be used as the computer’s connection to the network. Switches and routers are some of the devices that provides traffic control strategies.

There are different types of computer networking but in a corporate house the requirements are different. Total system availability requires coordinated service that covers your hardware, network and software requirements. Network system management is a part of network support service that helps to integrate and manage multi-platform distributed systems, networks and multi-vendor services. Multi-vendor services refer to the support of system technologies.

Any sort of disruption in efficient network management can lead to huge economic losses or revenue losses amounting to millions. This can put several jobs in jeopardy. The work of a network manager is to provide services on a global basis with 99.999% efficiency, often referred as “five nines”.

Though efficient Network management you can keep track of equipment’s that need replacement. For instance a card in a switch might need replacement. In such cases, another tool, that is the work order system can be utilized in a network management. Following this a new work order is created that specifies the card to replace. The identifier of the trouble area is put in as thee related information and thus the problem is sorted out.

Computer infrastructure professionals are critical for the functioning of a typical software firm, and are highly respected by peers. It totally depends upon the experience of the network administrator as it opens up opportunities for him/ her to further experiment in their career. As a matter of fact, there are ample examples where CIM professionals, after working in the industry for some time, have vented out and started their own firm.

Sizing of Hardware

After finalizing the complete requirements of the computer hardware required for implementation decision should be taken regarding the sizing of the required hardware. Sizing of hardware means size of the computer hardware according to the space availability. Due to the improvement in information Technology the size of the computers and other peripherals has been reduced considerably so that the space can be managed economically. For example, introduction of LCD (Liquid Crystal Display) Monitors occupies very lesser space when compared to the old CRT (Cathode Ray Tube) Monitors. LCD Monitors are slim and fits even in a smaller area. But CRT Monitors require huge table space for their installation. The size of the Desktop computer is also designed compactly which is suitable for low space area.

The size of the computer hardware plays an important role in the infrastructure management. Planning the size of the computer hardware equipment’s is done according to the availability of space reserved for computer hardware. Nowadays laser printers are used widely by all users because of the better quality and compact appearance. Laser printers designed by Hewlett Packard, Samsung are very compact and occupy lesser space compared to the Dot Matrix Printers are old type printers which require more space and it is only used under special environment .Many of the business and other organizations prefer laser printers due to its compatibility and quality of printing.

The Central Processing Unit coms in miniature size which is very comfortable for low space environment. Many computer manufacturers have designed small CPU which consumers very less space. The older CPU was big and heavy so that it was consuming large space. We have option of selecting the size of the CPU now according to the availability of the space. New miniature and highly colorful CPU are designed by computer manufacturers for better space management. Laptops can be used comfortably in a low space environment instead of Desktop computers.

The sizing of the computer hardware also includes the Display size of the Monitors come in variety of screen sizes such 15 inches, 17 inches, 19 inches, 19 inches and 21 inches. As the screen size of the Monitor increase, this leads to thee increase of the entire size of thee Monitors. So, the requirement of screen size of the Monitors should be decided according to the requirements and space availability. Certain projects such as AUTOCAD, Graphics and Multimedia require large screen monitors for better visibility. So such an environment demands Monitors with big screen which require more space Most of the companies require standard sized Monitors which will be more comfortable and also cost effective, since increase of screen size of the Monitors increases the cost of the Monitors.

The Sizing of the computer hardware depends upon the various factors which are discussed below:


The Nature of work determines the size of the Monitor. Multimedia and Graphic applications always require large screen Monitors. Computer environment based on normal development work, clerical work etc. requires normal screen Monitors. Requirement of additional hardware such as Speakers, Microphone, and Scanners etc. also depends upon the nature of work.

2) SPACE AVAILABILITY Space is one of the important constraints for designing and deciding the computer hardware requirements. Computer hardware equipment should be planned according to the space availability. The size of the computer hardware equipment should be decided according to the availability space. Poor planning of computer hardware equipment, not according the space availability, leads to congestion.


The sizing of the computer hardware is also influenced by the financial resources available for computer hardware. The sizing of the hardware equipment’s also depends upon the financial estimates allocated for the computer hardware equipment’s. Budgets should be prepared for the computer hardware equipment’s required for the project.

Sizing of hardware also refers to the selection of appropriate size and quality of computer hardware required for the Data Processing Environment. The quality and quantity of computer required for the Data Processing Work should be estimated carefully. The selection of computer hardware refers to the selection of size of the Visual Display Unit, Size of Printers, Size of Scanners, and Size of the Central Processing Units.

Sizing of computer hardware always depends upon the area available for computer hardware in the organization. Using of CRT Monitor requires large table size and it occupies a large space when it compared to LCD Monitors. LCD Monitors consumes less space and it is also comfortable for the users. Printers are an important computer hardware which plays a vital role in the Data processing Environment. Dot Matrix Printers occupies more area when it is compared to Inkjet printers and laser printers. Dot Matrix Printers are used for special purpose for taking instant carbon copies. Laser Printers and Inkjet printers occupies very small area and the letter quality is also good. So, It should be decided according to the output quality and output requirement and space availability of the organization.

Main Features of Sizing of Computer Hardware:

1) The size of the computer hardware depends upon the size allocated to the computer hardware in the organization.

2) The size of the computer hardware depends upon on the quality requirement of the organization.

3) The size of the computer hardware should be designed according to the infrastructure management.

Site Readiness

Site readiness refers to the stage where the site is completely ready for the starting thee project. The site should be completed in all aspects. A site with adequate electrical and networking points, adequate computer hardware and other equipments, and computer software can be said to be ready for the start of the project. The site readiness can be investigated physically. The site is not ready when the infrastructure is not properly designed and implemented. Site readiness indicates that all the infrastructure facilities were incorporated and all the necessary equipments were installed and the whole process is ready.

The site readiness indicates the completion of the infrastructure facilities given to the environment for the execution of the project.

Selection of Equipments

After the decision of requirement of equipments, selection of equipments according to the requirement of the project plays an important role in the Infrastructure Management. This stage of selection of equipments is an important stage of infrastructure management. This stage of selection of equipments is an important stage of infrastructure management. Equipments should be selected which fit into the environment and are suitable for the environment in various dimensions. Equipments selection is the process of selecting right equipment from the alternatives. Wrong selection of equipment may lead to the failure of the project. Equipments selection should be made based on the following considerations.

1. The cost of the equipment so that it should not exceed the budget or estimation made for the equipments.

2. The space to be occupied by the equipment so that it should not create congestion.

3. The suitability of equipment to the project.

4. The working life of the equipment.

Selection of correct equipment leads to the efficient performance of the project and easy attainment of the objectives of the project. Selection of equipment can be made easily by studying thee features and suitability of all optional equipments and alternative equipments. Equipment selection should be made according to the objective of the project. Equipments are very important source for the execution of the project.

Selection of equipments can be done easily using Equipment Catalogues and Equipment Working Demo. Equipment should be favorable from all dimensions of the project. Equipment should be selected keeping in view of the nature of work done in the project.

First issue is what type of computer. Unless you are always working in a fixed office, get a notebook computer. Desktops are cheaper and better valued but at some point, someone is going to want you to take the system to them. With the notebook, you just put it in a bag and go.

For the video computer, lots of RAM is important, right? Surprisingly no, you are better off with a faster CPU. Video does not use much memory, as long as the CPU can keep up with the camera. Only a couple of frames are in memory at any one time, the rest should be on the disk or still in the camera. I suggest a minimum of 128 MB of memory: today most computers come with 256 MB.

Which make of computer is better? Today computers are all generally the same under the keyboard: Intel makes most of the important parts of the computer. We use ACER computers because they are the third largest computer maker in the world and have a good international service network, Any new computer with over 1 Ghz CPU is enough for swing analysis. I usually recommend to people to buy the amount of computer hardware depending on how long they want to own the computer. If you want the computer to last 5 year get 2.5 Ghz, 3 years 1.5 Ghz will be fine. Why use time as a definition for power? Because Microsoft has this tendency to make bigger and bigger applications for which you need more and more power.

The screen: You might have seen these “Day light” screens for notebook computers. Yes, you can see these screens better in very sunny conditions but the screen size is only 10”, and low 800x600 resolution, this compares to 15” screen at 1024x768 resolution. Finally, daylight screens are expensive because not many are sold. We have also found that the TFT/LCD screens are good enough to see in sunny conditions, place the screen so that the sun is directly on it, this maximizes the light going into the screen so it can be reflected.

Hard Drive space is simple: more is better. Video is a big data consumer; even with compression, video files of 5 Meg are common. I suggest at least a 20 Gig hard drive, 30 Gig is better. You will see hard drives of different speeds: 7200RPM, 5400RPM are the current common speeds. The faster hard drive is better ,especially for video, because you are streaming large single pieces of data to the drive, Almost all notebook drives are 5400 but this will change in the next couple of months.

CDWR drives are a great feature to add to your computer, because this allows you to give recorded lessons to students. Most CD writing drives are now combo DVD and CDWR. This does not mean they write DVD but they can read them. There is a new generation of DVD writers coming, but these devices are expensive, the disks are expensive, and DVDs are not as universal as CDs. Finally, you do not need the extra space a DVD offers: 3 hour lessons are very rare.

Printers: are the last piece of hardware I would like to talk about. Today’s ink jet printers can produce amazing results on normal paper at very low cost ( $100.00). Having one of these printers around allows you to print motion sequences and other handouts that helps in the marketing of your business but also adds an additional revenue stream. I do suggest looking for a printer that has separate color ink cartridges. With outdoor sports you tend to print lots of green which will empty two of the color cartridges but leave thee other full.

If you already have a computer you want to use for video analysis, most of the features I have mentioned here can be added to your computer. Things like Firewire, USB 2.0, ports come in both PCMCIA (CardBus) and PCI card formats. CD Writers can also be plugged into USB ports. The only problem with external CD writers is that they need external power so when you are in the middle of a field fairway you can’t write CDs. The same goes for a new computer, make sure there is room to expand. Look for things like USB2.0, IEEE 1394 port, and what is required to added RAM to the computer.

If you are just starting with all this technology, it all looks like too much to figure out. Really, it is like everything else in this world, it is simple, once you know it. The simplest computer in the world has only one button but once you know that button, you will want another one. Look carefully at the growth path of the systems you buy, simple to start but expandable when you have a good handle on the basis. Starting small reduces the total cost of system ownership, because you are not paying for features you will not use for a couple of years.

A data center requires more precise control over temperature, relative humidity, airflow, and contaminants than does a typical office environment. If the specific need of this environment is to be met, they must be addressed throughout the design and construction of the room. Prior to installation of the hardware, the room should be inspected to identify any remaining exposures, and all surface in the room must be appropriately decontaminated. The final punch-list items should include specific tasks designed to bring the computer room environment within specific parameters. The following actions should be performed in the general order listed.

Perform a general construction decontamination of the room. A rough cleaning of the room should first be conducted to remove all major construction- related debris. Low- grade industrial vacuums can be used at this stage to remove heavy deposits. This stage of the cleaning would include those steps typical to any construction project, and is aimed primarily at appearance.

The vapor barrier of the room should be checked. Any breaches that could allow significant moisture migration should be noted and fixed. In the sub floor void, these can include perimeter penetrations around pipe or conduit passages, cracks in the deck or perimeter walls, expansion joints or open ducts or walls that connect the subfloor void to the ceiling void or to other floors. In the above floor space, these can include holes or cracks in the perimeter walls, gaps around pipe or duct penetrations, interior or exterior windows, access windows or perimeter mail slots, gaps around doors or light fixtures with designed air vents. Above the drop ceiling, breaches can include gaps around pipes, ducts or conduit. Gaps around structural beams or between perimeter walls and corrugated roofing materials, open ceiling voids to other areas, gaps around access doors to the roof or other floors or roof vents.

Load test the generations, UPS and other power infrastructure components. Perform functionality tests to ensure the data center is ready to accommodate on-line computer operations.

Perform a final inspection on the environmental support equipment. Check for proper installation and functioning of fall equipment. Check for proper installation and functioning of all equipment. Put the air conditioners and humidifiers through their cycles by adjusting their set points to force them into stages of cooling , heating, humidifying, dehumidifying, etc. by this stage, chillers, UPS< generators and all other similar support units should have been tested. Make any necessary adjustments.

Prior to the installation of the hardware, but during and after the construction cleaning, the air conditioners should be run continuously to filter the room air. These units need not be cooling, as the primary purpose of this action is particulate arrestation. Ideally 60% efficiency filters will be used at this point. These filters will be replaced prior to hardware installation, as they will likely become inundated with particles that can be re-dispersed by the sub floor pressure forcing air through a unit in a reverse pattern should one of the air conditioners b turned off.

After the construction cleaning, it is essential that a through decontamination of the room surfaces be conducted to remove any residual particulate in final preparation for the installation of the hardware. Low –grade vacuum equipment, such as that used during the construction phases of the project, lacks the filtration necessary to arrest most particulate. Vacuums quipped with High Efficiency Particulate Arrestance ( HEPA) filtration must be used at this stage. In addition, special equipment and procedures should be employed, as outlined in the later sections of this report.

Prior to the hardware installation, the room should be stabilized within the goal specifications established within this document. It may be difficult to achieve precise balancing and appropriate environmental support equipment cycling in the controlled space until the designed heat load is installed, but conditions should be mad as balanced and appropriate as possible prior to installation. Temperatures, relative humidity levels, subfloor pressurization, room pressurization and airborne particulate levels should all be checked.

Whether a designed-built room, or a renovated area, the computer room must be able to accommodate diverse hardware designs and requirements. The mission of a computer room rarely remain stable, and the hardware designs and requirements. The mission of a computer room rarely remains stable, and the hardware designs and configurations change as technology and the goals of the company evolve. While the future of a computer room can rarely b anticipated, it is essential that the hardware areas are planned in such a fashion as to allow for seamless adaptation to the changing needs.

The main criteria driving the type of hardware in the room will be determined by the applications of the business. The following general guidelines should be used in planning the current layout of the sun microsystems hardware and support equipment, and to help in preparation for future changes.

Do not determine air conditioner placement based on convenience. Often air conditioners are placed around the perimeter of the room because of the convenience of piping, water detection and other issues. This is not normally the most effective placement for the units, except in some smaller rooms. The hardware heat- load of thee room will change repeatedly over the life of the room, and it is important that the primary criteria in the determination of the air conditioner placement be its effectiveness in addressing the current planned load, and their adaptability to changes in configurations.

Consider the air-flow patterns of the hardware being installed. Does it draw supply air directly from the subfloor? Does it draw air from the ambient room above the floor surface? Is the air exhausted out the back or top of the cabinet? If the hardware is not in a cabinet, or if it is in an open rack system, what is the design of the individual components? Does air flow side-to side, front- to back, front-to-top or bottom- to –top? Be sure that the units are not laid out in a fashion that exhausts air from one unit into the intake of the next.

Provide adequate aisle space to allow for unobstructed passage, and to allow for the replacement of cabinets within a string without interference to neighboring units. Strings of cabinets should be kept to manageable lengths so as to allow clear passage between aisles in the event of an emergency, or in order to respond to a problem with a unit. Long, unbroken strings necessitate a significant amount of time to move from one aisle to another, or even from the front of a unit to its back.

Design the operator traffic patterns to minimize the possibility of accidental contact with sensitive components. Avoid placing operations in a fashion that necessitates personnel traveling through a sensitive area, such as the main machine room, to a less sensitive area. For example, operators should not have to travel through the computer areas to get from the command center to the print room.

Position hardware in strings or rows that run perpendicular to the air handlers. This allows for an unobstructed return of heated air back to the air conditioners. Where possible, avoid air-flow patterns that necessitate the air travelling over tall hardware cabinets to return to the air conditioners.

Access to the computer rooms should be strictly regulated, and limited to only those personnel necessary for its operation. All personnel working within the data center should have at least a basic under understanding of the sensitives of the hardware so as to avoid activities that pose a direct risk to the hardware. Accidental contact with hardware buttons, cable connections, terminals or emergency response controls can all cause system interruptions of varying degrees.

All points of access to the computer rooms and other sensitive areas should be controlled by checkpoints or coded card readers to restrict access to authorized personnel. Security personnel should also remotely monitor points of entry via camera.

The raised access floor system provides the flexibility in wiring, hardware location and air conditioning. The raised floor should be constructed of 24 inches x 24 inches ( 61cmx 61 cm) panels interchangeable with perforated titles for air distribution or custom cut tiles for cables or utility passage. This design isolates data lines, power cables and piping to provide a safe environment for operators and to protect hardware operations. In addition, the raised floor design provides a means for flexible and efficient air distribution to thee hardware. While it is possible to accommodate a small number of hardware units in alternately designed rooms, it is highly recommended that large numbers of hardware cabinets are installed in a raised floor system.

Whether the data center is located in a new or existing structure, the building must be properly prepared to receive the hardware prior to its installation. Construction projects are expensive, and the construction of controlled data center areas is more expensive than most. There is always a great deal of pressure to meet deadlines and keep within costs, but it is extremely important that this is not achieved by cutting corners and setting for inferior workmanship.

Power quality issues are often difficult to identify, and can be even more difficult to correct . Often, the symptoms are very similar to those caused by other environmental problems or software issues. The most effective means of mitigating power problems is through the appropriate design of the system. The goal of the power system design should be to provide power, at appropriate levels and quality, without interruption. Integral to this task is the incorporation of sufficient redundancy, and the elimination of single points of failure. While Sun Microsystems equipment is designed to be robust and tolerant of most electrical problems, a thoughtfully designed power infrastructure is an important part of any facility. The following areas should be addressed in the design systems for a computer room.

An Uninterruptible Power Supply ( UPS) should be installed to carry:

• 100% of the computer hardware load for a period at least long enough to transfer the equipment to alternate utility feed or back-up generators.
• 150% of the load to accommodate fault overload conditions.

On – line UPS that runs continuously should be used as opposed to an off-line unit. The on-line UPS filters, conditions, and regulates the power. Battery back-up should be capable of maintaining the critical load of the room for a minimum of 15 minutes during a power failure to allow for the transfer of power to an alternate feed or generator.

If a UPS is not used as a bare minimum, then surge suppression should be designed into the panels and a stand-alone isolation/regulation transformer should be designed into the power system to control the incoming power and protect the equipment.

The power distribution equipment for computer applications should be installed as close as reasonable to the load. All loads being supported need to be identified and evaluated for compatibility with the computer equipment. Heavy loads that are cyclic, such as elevators, air conditioners, and copy machines should not be connected directly to the same source as the computer room equipment.

Backup power generators should be installed to carry the load of both the computer equipment, as well as all necessary support equipment ( such as air conditioners). Depending upon the critically of the site , it may be acceptable to use the UPS and multiple utility feeds without generators.

Grounding is an extremely important electrical consideration for the proper operation of electronic equipment. The ground conductor provides a designed path to ground ( earth). Grounding design in a data center environment must address both the electrical service as well as the equipment. Grounding design should comply with Article 250 of the National electrical Code ( NEC 250---Grounding) unless superseded by local codes. The National Electric code ( NEC ) section # 250-51, Effective Grounding Path states:

The path to ground from circuits, equipment and conductor enclosures shall: (1) be permanent and continuous; (2) have capacity to conduct safely any current likely to be imposed upon it; and (3) have sufficient low impedance to limit the voltage to ground and to facilitate the operation of the circuit protection devices in the circuit. The earth shall not be used as the sole equipment grounding conductor.

A properly designed grounding system should have as low an impedance as is practically achievable for proper operation of electronic devices as well as for safety. It is also important that thee ground should be continuous from the central grounding point at the origin of the building system. Electronic equipment can be sensitive to stray currents and electronic noise. It is important to utilize a continuous, dedicated ground for the entire power system so as to avoid a ground differential between various grounds being used.

All metallic objects on the premises that enclose electrical conductors or that are likely to be energized by electrical currents ( e.g., circuit faults, electrostatic discharge, and lightning) should be effectively grounded for reasons of personnel safety, fire hazard reduction, protection, of the equipment itself, and performance. Solidly grounding these metallic objects will facilitate over current device operation and permit return from EMI filters and surge suppressors, connected line-to-ground or line-to-chassis, to flow in the proper fashion.

The common point of grounding can be connected to any number of sources( water piping, driven earth rod, buried grid, building steel, etc.) at the service entrance. It is important that whatever the source, the ground is carried through the entire system from this source. Ideally, the central point of grounding at the service entrance will be connected to multiple ground sources, such as the building steel, buried grid and cold water piping. If they are connected at the same point, there is no potential for ground loops, yet a redundancy is achieved. A water pipe used for a ground could rupture, building steel could have accumulated resistance over several floors. By tying into all of these, the possibility of a disruption is greatly minimized.

Within the data center, a single point of disconnect for all electronic system is required by NEPA 70 and NEPA 75 at each point of entry. Multiple discount means for these power systems are also acceptable, but in either case, the switches must be unobstructed and clearly marked. Protective covers may be placed over the buttons to avoid accidental contract, but access cannot be locked out. This switch should disconnect power to all computer systems, HVAC, UPS and batteries. If the UPS is located within the data center, the disconnecting means must stop power to this unit. If the unit is located within the data center, the disconnecting means must stop the supply from this unit to the room. Exceptions to this rule include small UPS ( 750 volt- amperes or less) within the room.

Even though it is not required by code, it is still recommended that all power sources in the room, including the exceptions listed, be controlled by the disconnecting means so as to provide the greatest degree of safety to the hardware and personnel. It could be these systems, or the gear they supply, that are the cause of the fire.

All wiring and cabling should be designed and installed in accordance with the requirements outlined in this document and the National Electrical Code ( NFPA 70) or superseding national or local codes or standards. In some cases, the recommendations provided in this document may exceed the minimum recommendations outlined in NFPA 70.

All wiring and cabling should be run in an orderly and efficient manner. This is particularly important beneath the raised floor. The nature of the data center requires frequent modifications, and it is extremely important that obsolete cabling be minimize the potential for disruption due to disconnection of cables when work is taking place.

Whenever possible, data and power cables should intersect perpendicularly so as to minimize the potential for generation of disruptive electronic noise on the lines. For the same reason, try to run data and power cables at least 6 inches apart when they are parallel. Unused or partially connected cables can also act as antennas. Cables should not be cut in place and left in the sub floor void.

Temporary extension cords should not be used in the sub floor void. If these are used above the raised floor, proper safety precautions should be taken to ensure that they are not a tripping hazard, and that they will not be damaged.

Do not use power strips with switches, surge protectors and fuses within the data center. These can counter some of the designed protections of the hardware, and are not necessary. In addition, the switches on these strips can easily be tripped, causing unwanted outrages. This is a particular susceptibility when they are placed on the raised floor beneath desks, or on the edges of aisles.
