memory boards, if applicable.
4. Replace the DIMMs with a remaining bank of memory.
5. Replace the memory board, if applicable.
6. Replace the midplane board.
IMPORTANT: If replacing the SPI board or clearing NVRAM, you must re-enter the server
serial number through RBSU, see “Re-entering the server serial number and product ID”
(page 48) .
