Upgrading or Adding a CPU Card
You may find media included with your new CPU card. Look at the label to
determine the minimum level of firmware required for the new CPU card.
Attention: If your system has two CPU cards, do not mix different speed CPU cards
in your system.
1. Check the Service Processor firmware level (see Chapter 4, “Service Processor
Menus” on page 4-1).
2. Update the Service Processor firmware if necessary (see Chapter 4, “Service
Processor Menus” on page 4-1).
3. When the system reboot is complete, shut the system down.
4. If you have not already done so, remove the covers as described in “Removing
Both the Front and Side Covers” on page 5-10.
5. Remove the I/O planar cover as described in “Removing the I/O Planar Cover”
on page 5-16; then return here to determine your next step.
