3.If the sequence is still abnormal:

a.Remove the interface module by unscrewing the two retaining screws on the module’s front panel. Pull the module out using the “ears” on the front panel.

b.Carefully but firmly press down on all socketed components.

c.Re-install the module. Make sure the module is properly seated and tighten the retaining screws.

d.Reset the ATX and observe the power-up sequence.

4.If it is still abnormal, contact Cabletron Systems Technical Support.

5.3.2Connectivity Problems

If the Token Ring module powers up normally but the workstations are unable to communicate:

1.Check the LEDs for abnormalities which may help indicate the source of the problem. (LED behavior during normal operation is explained earlier in this chapter.)

2.Check the status of the ports using LCM.

3.Make sure the ring speed for all stations on the same ring are set for the same speed. One station configured for a different speed may disrupt ring operation.

4.Check for loose connections between the Token Ring module and the MAU and between the MAU and the workstations. Remember, the Token Ring ports cannot be connected directly to workstations. Also refer to the MAU’s documentation for additional information, such as wrapped or open ports.
