2.10.3 Individual Station Problems

If an inserted station with a GREEN status LED cannot access network 
services, then the problems may involve the server. If a particular user 
cannot log-on to a server perform the following:

•

Use another station to attempt to log-on from the same port. 
A successful attempt indicates the problem is likely with the original 
station; conversely, if no other station can log-on, then the problem is 
likely to be at the server.

•

For TCP/IP devices only: If no stations can log-on to the server use a 
PING utility to determine if IP traffic is reaching the server. If the 
server responds to PING requests, then the problem is almost 
definitely with the server or on the application layer. Consult your 
server documentation for troubleshooting tips.

Table 2-3

LED Activity And Corrective Actions 

LED Activity

Meaning and Corrective Action

GREEN

Link established, (normal operation) associated 
station inserted into the ring. If the station cannot 
access network resources (such as servers) see 

Section 2.10.3

.

Blinking GREEN
(Fiber ST Only)

The connection from the upstream device to the 
Receive connection is complete but the port is 
wrapped. Check the other end of the cable. 
Ensure the port on the downstream device is 
attached correctly and enabled.

OFF

No phantom current present (no Rx activity in the 
case of fiber ST ports). Try resetting the station. 
Use a different cable, or try a different port. If 
possible use a different CM to isolate the 
problem.

Blinking RED
(Lobe Only)

Speed-fault condition caused the port to wrap, 
adjust the speed of the station or the CM.
