Manually Initiating a Packet Processing Card Migration
When the system boots up, all installed PACs/PSCs enter the ―standby‖ mode. The standby mode indicates that the card
is available for use but is not configured for operation. Installed components can be made active through the software
configuration process. Cards that are not configured to enter the ―active‖ mode will remain in standby mode for use as
redundant components.
is available for use but is not configured for operation. Installed components can be made active through the software
configuration process. Cards that are not configured to enter the ―active‖ mode will remain in standby mode for use as
redundant components.
In the event of PAC/PSC critical failure, tasks will be automatically be migrated from the active card to a redundant
card in standby mode. The line card installed behind the PAC/PSC that was formerly active will still be used to maintain
the interfaces to external network equipment. Installed Redundancy Crossbar Cards (RCCs) will provide a path for
signalling and data traffic between the line card and the now active PAC/PSC. Therefore, redundant PACs/PSCs do not
require that line cards be installed behind them.

In the event that an issue arises that is not severe enough for the system to perform an automatic migration, a manual
migration can be invoked. Follow the instructions below to manually initiate a PAC/PSC migration. These instructions
