CABLE LABELING AND CONNECTION RECORDS
When planning a network installation, it is essential to label the opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter-connected devices, isolate faults and change
your
topology
without need for unnecessary time consumption.
To best manage the physical implementations of your network, follow these
guidelines:
Clearly label the opposing ends of each cable.
Using your building’s floor plans, draw a map of the location of all network-
connected equipment. For each piece of equipment, identify the devices to
which it is connected.
Note the length of each cable and the maximum
cable
length
supported by
the switch ports.
For ease of understanding, use a location-based key when assigning
prefixes to your cable labeling.
Use sequential numbers for cables that originate from the same equipment.
