Switch Maintenance Procedures

This chapter describes the configuration changes that are needed after a switch has been initialized,

started, and configured, and you want to do any of the following tasks:

• Manual reset of the PXM

• Add cards

• Replace cards

• Upgrade cards

• Decommission a card slot

• Decommission an RPM slot

Service module and SRM slots must be decommissioned when you want to change the type of card that

runs in the slot.

Manually Resetting the PXM

If a PXM should ever require resetting and the CLI is not working, there is an escape sequence that

allows you to reset the PXM. Use the following procedure to reset a PXM.

Step 1 Establish a physical connection to the PXM through the Console Port (CP) connector on the PXM-UI-S3

or PXM-UI-S3/B back card.

Caution Anyone with physical access to the switch CP can reset the password, deny access to other users, and

reconfigure the switch. To prevent unauthorized switch access and configuration, the switch should be

installed in a secure area.

Step 2 Press ESC, CTRL-X to reset the PXM.
