TROUBLESHOOTING
2. If the remote station is ready and the LNK LED is on, but no data
passes through the port, one of two conditions may exist:
•
Network management has disabled the port.
•
The port is segmented either because the collision detector was
on for more than 110 sec. or the SEHI detected more than 32
consecutive collisions on the attached segment. The affected
port remains segmented until a good packet is transmitted/
received without collisions.
If the LNK LED is still not on, contact Cabletron Systems Technical
Support.
5.2 USING LANVIEW
The SEHI incorporates the Cabletron Systems LANVIEW Status
Monitoring and Diagnostics System. LANVIEW LEDs can help
diagnose problems such as a power failure or a cable fault. The SEHI
includes the following LANVIEW LEDs:
•
PWR, for power status
•
CPU, for board status
•
RCV (Receive), LNK (Link), and CLN (Collision) for Ethernet
status.
Figure 5-1 provides a quick reference chart of LED locations and
definitions. This chapter also includes a detailed description of each
LED.
