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.

•Differentiate between racks by naming accordingly.

•Label each separate piece of equipment.

•Display a copy of your equipment map, including keys to all abbreviations at each equipment rack.
