TESTING AND TROUBLESHOOTING

4.2USING LANVIEW LEDs

LANVIEW is Cabletron Systems’ built-in visual diagnostic and status monitoring system. Using LANVIEW, your network troubleshooting personnel can quickly scan the LANVIEW LEDs to observe network status or diagnose network problems, and determine which node or segment is faulty. Figure 4-1 describes each of the front panel LANVIEW LEDs.
