Design and Installation Considerations for Cable Support

When designing your network, you must take cable management into account. In order to support existing infrastructure, and plan for future growth, there are a number of considerations that should be made throughout the design process and installation. Some important things to keep in mind include:

Bonding and grounding is important when installing any cabling support product. Be sure that all racks, cabinets, and pathway support products are properly bonded and the system is grounded.

Installation of overhead and underfloor supports should be done in a matrix type fashion that allows cables to be routed from point to point anywhere in the data center.

Be sure the heaviest cable is on the bottom of the tray or separated from the lighter cables. This will prevent the heavier cable from stressing the lightweight cables.

Grounding and bonding is very important when installing any cabling support product. Be sure that all racks, cabinets, and pathway support products are properly bonded and the system is grounded.

Allow room for future growth. All cable tray and ladder rack should be sized to accommodate at least 50% growth after the initial install.

Be very careful about stressing the cable. Be sure to use sweeping 90-degree bends always when transitioning from the pathway support and the racks or around corners.

Separate the copper cables from the fiber cables if possible.

Avoid mounting any cable components in locations that block access to other equipment inside and outside the racks.

Avoid routing pathways with copper cables near equipment that may generate high levels of electrometric interference.

Avoid areas around power cords, florescent lights, building electrical cables and fire prevention components.

Care must be used in the engineering process when choosing Patch Cable and Pre-Terminated Fiber Cable lengths.

When utilizing Pre-Terminated cables, slack will always be a potential problem. If it is allowed it to build up it creates many problems such as, clogged up pathways, excessive weight overloading the supports, and reduced airflow.
