Caution! Do not attempt to hot-remove or hot-add a memory
board in a non-redundant configuration. If your server is not
configured in the BIOS setup utility for maximum compatibility,
memory RAID, or memory mirroring, you must power down your
server before removing or installing any memory board or DIMMs.
For instructions, see “Cold removal of memory board instructions”
described on page 70 and “Cold insertion of a memory board
instructions” described on page 71.

Memory board replacement options
The server include the following memory board replacement options:
•
Memory hot-replace - While the system is in operation and
configured with a RAID or mirroring configuration, you can
replace a failed memory board. The replacement board must
include identical memory capacity. The system will test, initialize,
and rebuild the data on the memory board and then include this
board in the system memory configuration. The activity is
transparent to the OS. For instructions on how to hot-replace the
memory board, see “Removing a hot-plug memory board” on
page 53.

•
Memory hot-add - You can increase the memory capacity of the
system while the OS is active and if it is in a RAID or mirror
configuration. If your server is in a RAID configuration, you can
remove only one memory board at a time to upgrade the memory
or replace the memory board. In a mirror configuration, you can
add an additional two mirrored memory boards. In a maximum
compatibility configuration, a new memory board can be added to
an empty slot. When the initialization is complete, the operating
system is informed of the new memory. For instructions on how to
hot-add the memory board, see “Installing a hot-plug memory
board” on page 54.

Memory cold-plug operation - If your server is not in a RAID or
mirror configuration, you must turn off the server to add or
replace the memory board. To replace or remove a memory board
using cold-plug operation, see “Installing a memory board” on
page 71 and “Removing a memory board” on page 70.
