Evaluating and Meeting Cable Requirements

Extreme Networks BlackDiamond 10K-Series Switch Installation Guide 29

Installing Cable

Consider the following recommendations when you connect cable to your network equipment:

• Examine cable for cuts, bends, and nicks.

• Support cable using a cable manager that is mounted above connectors to avoid unnecessary weight

on the cable bundles.

• Use cable managers to route cable bundles to the left and right of the network equipment to

maximize accessibility to the connectors.

• Provide enough slack—approximately 2 to 3 inches (5.08-7.62 cm)— to provide proper strain relief as

shown in Figure 6.

• Bundle cable using velcro straps to avoid injuring cables.

• If you build your own cable, ensure that cable is properly crimped.

• When installing a patch panel using twisted pair wiring, untwist no more than 1 inch (2.54 cm) of

the cable to avoid RF interference.

• When required for safety and fire rating requirements, use plenum-rated cable. See your local

building codes for determining when it is appropriate to use plenum-rated cable, or refer to IEC

standard 850.

• Keep all ports and connectors free of dust.

NOTE

Unshielded twisted pair (UTP) cable can build up ESD charges when being pulled into a new

installation. Before installing category 5 UTP cables, discharge ESD from the cable by plugging it into a

port on a switch or any network device that is not powered on.
