Manually Initiating a Packet Processing Card Migration
When the system boots up, all packet processing cards 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.
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.
In the event of the critical failure of a packet processing card, tasks will be automatically be migrated from the active
card to a redundant card in standby mode. The line card installed behind the packet processing card 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 packet processing
card. Therefore, redundant packet processing cards 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 packet processing card migration. These
instructions assume you are at the root prompt for the Exec mode:

Step 1
Initiate a manual packet processing card migration by entering the following command:
card migrate from original_slot# to final_slot#
You will receive the following prompt:
Are You Sure? [Yes|No]:

Step 2
Press

to start the migration.
Step 3
Verify that the migration was successful by entering the following command at the prompt:
show card table
Check the entry in the Oper State column next to the packet processing card that was just migrated from. Its state should
be Standby. The state of the packet processing card migrated to should be Active.

Manually Initiating a Line Card or SPIO Switchover
Ethernet line cards are installed in the half-height slots at the rear of the chassis. This design allows for two half-height
line cards to be installed behind every application card (vertical redundancy). With two line cards installed, booting their
associated application card causes the card in the upper-rear chassis slot to automatically be made active while the card
in the lower-rear chassis slot will automatically be placed in standby mode. In the event that the active card experiences
a failure, the system will automatically switch traffic to the standby card in the lower slot.

The XGLC is a full-height card that supports 1:1 side-by-side redundancy. Side-by-side (horizontal) redundancy allows
two XGLC cards installed in neighboring slots to act as a redundant pair. Side-by-side pair slots for the XGLC are: 17-
18, 19-20, 21-22, 23-26, 27-28, 29-30, and 31-32. If the XGLCs are not configured for side-by-side redundancy, they
run independently without redundancy.
