Figure 84 SAS Backplane Board Removal and Replacement
Replacing the SAS Backplane Board
To replace the SAS backplane board, follow these steps:
1. Hold the SAS backplane board by the sheet metal bracket and guide it toward the front of
the chassis until the four keyway slots on the board seat onto the locking studs (Figure 84).
2. Push the board to the right to plug it into the socket on the interconnect board. The release
lever locks into place when the board is fully seated (Figure 84).
3. Replace the interconnect board air baffle (Figure 85). See “Replacing the Interconnect Board”
(page 231).
CAUTION: When reconnecting the SAS cables, note the labeling on the channel cables.
Both cables and sockets are clearly marked with the correct channel. Match each cable with
the appropriate socket on the SAS backplane board. If the cables are mismatched, the server
operating system may not reboot.
4. Reconnect the SAS cables into the connectors on the SAS backplane board (Figure 84).
5. Replace the SAS disk drives. See “Replacing a Hot-Pluggable Disk Drive” (page 174).
6. Replace the air baffle (Figure 83).
7. Replace the clear plastic cover.
