Installing Cable - Extreme Networks Summit X450a-24tDC Hardware Installation Manual

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 49.
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.
Use plenum-rated cable when it is necessary for safety and fire rating requirements. Consult your
●
local building codes to determine when it is appropriate to use plenum-rated cable, or refer to IEC
standard 850.
Keep all ports and connectors free of dust.
