Chapter 6: Troubleshooting
2.If the remote station is ready and the LNK LED is on, but no data passes through the port, one of the following conditions may exist:
a.Network management has disabled the port. Correct this condition by enabling the port through network management.
b.The port is segmented either because the collision detector was on for more than 110 ∝s or the SEH 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 off, contact Cabletron Systems Technical Support.
6.2USING LANVIEW
The SEH incorporates the Cabletron Systems LANVIEW status monitoring and diagnostics system. LANVIEW LEDs help diagnose problems such as power failure or cable fault. The SEH includes the following LANVIEW LEDs:
•PWR, for power status
•MGMT, for management status
•RCV (Receive), LNK (Link), and CLN (Collision) for Ethernet status
Figure 6-1 provides a quick reference chart of LED locations and definitions. This chapter also includes a detailed description of each LED.
