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 6-34).

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 6-34).

3.Replace the interconnect board air baffle (Figure 6-35). See “Replacing the Interconnect Board” (page 252).

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 6-34).

5.Replace the SAS disk drives. See “Replacing a Hot-Pluggable Disk Drive” (page 190).

6.Replace the air baffle (Figure 6-33).
