Port Insertion Problems

Symptom: The Act LED on a token ring port does not ﬂash for a period of 15 to 20 seconds.

No ﬂashing on the Act LED on a token ring port typically indicates port insertion problems.

To resolve the problem, follow these steps:

1.Verify that the port is not operational by accessing the SpeedView multicast frame transmit and receive count statistics (Mcst xmit and Mcst rcv). Verify that the statistics are updating regularly over a period of 15 to 20 seconds.

If the counts change, the token ring port is inserted and operating. If the port is operating but the Activity LED stays dark, the LED may be damaged.

If the counts do not change, the token ring port is not inserted or enabled. Proceed to the following steps to verify proper installation, conﬁguration, and connection for the port.

2.Verify that the cabling is correct.

See Appendix B, “Cables,” for information about the token ring port types and pin assignments for different connectors.

3.Using SpeedView, verify the following items:

•The appropriate port type is conﬁgured: Station, Hub, Bay/SNPX RO, RI–other, or RO–other.

For more information about setting port types, see “Token Ring Connections” on page 3-6.

•The port is enabled.
