The SAS backplane attaches to an interconnect board that functions as a link between the midplane
board and the SAS backplane.
WARNING!
Ensure that the system is powered off and all power sources are disconnected
from the server prior to performing this procedure.
Voltages are present at various locations in the server whenever an ac power source is connected.
This voltage is present even when the main power switch is off.
Failure to observe this warning can result in personal injury or equipment damage.
CAUTION:
Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
Removing the SAS Backplane Board
To remove the SAS backplane, follow these steps:
1.
Power off the server and disconnect the power cables. See
“Powering On and Powering Off
the Server” (page 78)
.
2.
If rack mounted, slide the server completely out from the rack. See
“Extending the Server
from the Rack” (page 143)
.
3.
Remove the top cover. See
“Removing the Top Cover” (page 144)
.
4.
Slide the SAS drives and fillers approximately two inches out of the drive bays. See
“Removing a SAS Hard Drive” (page 156)
.
CAUTION:
When disconnecting the SAS cables, note the labeling on the cables. When
reconnecting these 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.
5.
Disconnect the SAS cables from the connectors on the SAS backplane (1).
6.
Disconnect the SAS backplane power cable from the connector on the SAS backplane (2).
7.
Pull the release mechanism toward the front of the server to disengage the SAS backplane
from the server (3).
8.
Lift the SAS backplane off the guide posts on the SAS drive cage (4). Angle the board toward
the rear of the server and lift it out of the server.
