Figure 6-46 Removing and Replacing the SAS Backplane
Replacing the SAS Backplane
To replace the SAS backplane, follow these steps:
1.
Pull the release mechanism toward the front of the server and hold it there to allow the SAS
backplane to be installed.
2.
Align the three keyway slots of the SAS backplane with the guide posts on the disk drive
cage and guide the board down until it is flush with the SAS drive cage (4).
3.
Let go of the release mechanism to lock the board in place.
4.
Reconnect the SAS backplane power cable to the connector on the SAS backplane (2).
5.
Reconnect the SAS cables into the connectors on the SAS backplane (1).
CAUTION:
When reconnecting the SAS cables, note the labeling on the channel cables.
Match each cable with the appropriate socket on the SAS backplane. If the cables are
mismatched the server will not function correctly. Both cables and sockets are clearly marked
with the correct channel.
6.
Push the release mechanism toward the back of the server to secure the SAS backplane to
the server (3).
7.
Replace the SAS disk drives. See
“Replacing a SAS Hard Drive” (page 157)
.
8.
Replace the top cover. See
“Replacing the Top Cover” (page 145)
.
9.
If rack mounted, slide the server completely into the rack. See
“Inserting the Server into the
Rack” (page 144)
.
10. Reconnect the power cables and power on the server. See
“Powering On and Powering Off
the Server” (page 78)
