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