Extreme Networks 17001 manual Cable Labeling and Record Keeping, Installing Cable

Cable Labeling and Record Keeping

A reliable cable labeling system is essential when planning and installing a network. Maintaining accurate records helps you to:

●Relocate devices easily.

●Make changes quickly.

●Isolate faults in the distribution system.

●Locate the opposite end of any cable.

●Know the types of network devices that your cabling infrastructure can support.

Follow these guidelines when setting up a cable labeling system suitable for your installation:

●Identify cables by securely attaching labels to all cable ends.

●Assign a unique block of sequential numbers to the group of cables that run between each pair of wiring closets.

●Assign a unique identification number to each equipment rack.

●Identify all wiring closets by labeling the front panel of your Extreme Networks equipment and other hardware.

●Keep accurate and current cable identification records.

●Post records near each equipment rack. Include the following cable drop information: the cable source, destination, and jumper location.

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 to 7.62 cm), to provide proper strain relief as shown in Figure 66.

●Bundle cable using hook-and-loop straps to avoid injuring cables.

●If you build your own cable, be sure that connectors are 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 radio frequency (RF) interference.

●Discharge the RJ-45 Ethernet cable before plugging it into a port on the switch.

CAUTION

Unshielded twisted pair (UTP) cable can build up ESD charges when being pulled into a new installation. Before connecting any category 5 UTP cable to the switch, discharge ESD from the cable by plugging the RJ-45 connector into a LAN static discharge device or use an equivalent method.
