Cabletron Systems NB20E, NB25 E user manual Using Lanview

TESTING AND LANVIEW

5.Using a transceiver (5) and an AUI cable, connect another LAN-MD

(4) to the other segment connected to the bridge.

6.Select and run test 4 - NODE on the LAN-MD connected in the previous step.

7.Verify that this test passes. At least 100 packets should be sent and received by the bridge, with no errors. Packets will be sent from this LAN-MD to the other LAN-MD, acting as the Server, then echoed back.

When the NB20E or NB25E have successfully completed these tests, the bridge is ready for normal operation. If any failures were noted, please contact Cabletron Systems' Technical Support.

4.2USING LANVIEW

The NB20E and NB25E Two Port Ethernet Bridges use Cabletron Systems' built-in visual diagnostic and status monitoring system called LANVIEW. With LANVIEW, network troubleshooting personnel can quickly scan LANVIEW's LEDs to observe network status, or diagnose network problems. Figure 4-1 displays the LANVIEW LEDs on the NB20E and NB25E.
