Switching Between Redundant PXM Cards

When the switch has two PXM cards running in active and standby mode, you can enter the swtichcc
command to swap the roles of the two cards. Typically, you enter this command to switch roles so you
can upgrade the hardware or software on one of the cards.
Note The switchcc command is entered only when all cards are operating in active or standby roles. For
example, if a non-active PXM is not in standby state, or if a service module is being upgraded, the
switchcc command is not entered.
To switch operation from one redundant PXM card to another, use the following procedure.
Establish a configuration session using a user name with SUPER_GP privileges or higher.
Step 1
Step 2 Check the status of the active and standby cards by entering the dspcds command.
The dspcds command should list one card as active and one card as standby. If the cards are not in their
proper states, the switchover cannot take place.
To switch cards, enter the following command after the switch prompt:
