Design and Installation Considerations for Cable Support Products

In order to support existing infrastructure, and plan for future growth, there are a number of key considerations that should be made throughout the design process and installation. Some important things to keep in mind include:

  • 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.
  • 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.
  • 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.
  • 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.
