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.
