5.2.2 Connectivity Problems

1. Check for LED abnormalities, such as WRAP LEDs on, or THRU

LEDs or RX, TX LEDs not lit. (LED behavior during normal
operation is explained earlier in this chapter.)

2. Check the status of the 3F00-01/3F55-01 port using LCM. The status

can be either:

•

Wrapped – indicates breaks in the ring

•

Twisted – indicates that the two FDDI cables have been
incorrectly connected

3. Check that the MICs are keyed correctly. See Chapter 2,Connecting

to the Network for information about MICs.

4. Check for loose port connections.

5. Check to make sure the front panel screws are tight, so that the module

is firmly seated against the ATX backplane.

6. Check the connections to the ring.
