For an SCP-card-based chassis:

1. Using the Status - Alarms screen of the web interface, 

determine what alarms have been reported against the 
line card.

2. If a major alarm is indicated, check the Ethernet 

connections on the SCP card and DSL port card. Make 
sure they are plugged in.

3. Remove and reinstall the card.

For an MCP-based chassis:

1. Using the asynchronous terminal interface, choose Card 

Selection from the Main Menu to display the status of 
each line card.

2. If a major alarm is indicated, check the Ethernet 

connections on the MCP card and DSL port card. Make 
sure they are plugged in.

3. Use software to reset the line card (

A-A-E

).

4. Remove and reinstall the card.
