Cable Guidelines
NOTE
Building and electrical codes vary depending on the location. Comply with all code
specifications when planning the site and installing cable.
When running cable to the equipment, consider the following:
•
Do not run cables where they can be stepped on or rolled over.
•
Be sure cables are intact with no cuts, bends, or nicks.
•
If the user is making a cable, ensure that the cable is properly crimped.
•
Provide proper strain relief for cables.
•
Support cables using a cable manager mounted above connectors to avoid
unnecessary weight on the cable bundles.
•
Bundle cable using Velcro straps to avoid injuring cables.
•
Keep all ports and connectors free of dust.
•
Untwisted Pair (UTP) cables can build up Electrostatic Discharge (ESD) charges
when being placed into a new installation. Before installing category 5 UTP cables,
discharge ESD from the cable by plugging it into a port on a system that is not
powered on.
•
When required for safety and fire rating requirements, plenum-rated cable can be
used. Check the local building codes to determine when it is appropriate to use
plenum-rated cable, or refer to IEC standard 850.
•
In order to create enough space, QSFP cables connectors may need to be rotated
when plugging into alternate rows of switch components.
