If the backplane is not a 19.2 Gbps backplane, it is necessary to install a 19.2 Gbps backplane to obtain
19.2 Gbps operation. Contact Cisco Customer Service.

Upgrading to BCC-4 Cards

BCC-4 cards support 19.2 Gbps performance of the BXM cards.
The BCC-4 cards require that the backplane be either a 9.6 or 19.2 Gbps backplane. For more
Note
information, see the Verifying 9.6 or 19.2 Gbps Backplane section.
To upgrade to BCC-4 cards, use the following procedure:
Step 1 Remove the current standby BCC front and back card.
Note
Step 2 Replace with new BCC-4 front and back cards.
Wait for the standby updates on the newly installed standby BCC-4 to complete.
Step 3
Issue a switchcc command to utilize the newly installed BCC-4.
Step 4
Verify that the network is stable.
Step 5
Remove the current standby BCC front and back card.
Step 6
Step 7 Replace with new BCC-4 front and back cards that are identical to the current active BCC-4.
Wait for the standby updates on the newly installed standby BCC-4 to complete.
Step 8
The BCC-4 physical upgrade is now complete.
Step 9
After step 2, the node will contain a mix of an old type BCC and the new type BCC-4. This condition is
permitted only while the standby updates to the new BCC are in progress, which takes less than one hour.
You should keep the time during which this mixture of BCC types exists to a minimum by immediately
replacing the second old type BCC with the matching BCC of the new type.

If the change does not take place, it is necessary to change the backplane NOVRAM. Contact
