Using the Centillion EtherSpeedII Switch Modules

EtherSpeedII Switch Module Startup Failure

Symptom: All LEDs are solidly lit (do not blink) on the switch module.

To resolve the problem:

1.Ensure that an MCP module is present and operational with the appropriate version of software.

•The EtherSpeedII 10/100BASE-T switch module requires version

4.1.2software or greater.

•The EtherSpeedII 100BASE-FX switch module requires version

4.2.1software or greater.

2.Ensure that all modules in the chassis are firmly seated and that the retaining screws have been tightened.

3.Remove and reinsert the failing module.

If the problem persists, contact the nearest Nortel Networks Technical Solutions Center.
