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.
Consider the following recommendations when setting up a cable labeling system
suitable for your installation:
• Identify cables by securely attaching a label 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 distribution 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 distribution 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.
