TESTING AND LANVIEW
4-2
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.
4.2 USING 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.
