Replacing a SAS Riser (RAID Controller)
The SAS riser is a RAID controller card that has a designated position and motherboard connector inside
the server. To install or replace a SAS riser, follow these steps:
Step 1
Remove the SAS riser you are replacing. See
Figure 3-9
:
a.
Power off the server as described in the
“Shutting Down and Powering Off the Server” section on
page 3-6
.
b.
Slide the server out the front of the rack far enough so that you can remove the top cover.
Note
You might have to detach cables from the rear panel to provide clearance.
Caution
If you cannot safely view and access the component, remove the server from the rack.
c.
Remove the top cover as described in
“Removing and Replacing the Server Top Cover” section on
page 3-7
.
d.
Pinch and lift up the green retaining clip that secures the SAS riser to the chassis rear panel.
e.
Lift the SAS riser straight up from the motherboard connector.
Note
Lift up on both ends of the card evenly to avoid damaging its connector.
f.
Disconnect the SAS cables and any battery backup unit (BBU) cable from the SAS riser. See
Figure 3-10
.
Tip
Label the SAS cables when you disconnect them to aid correct connection to the new SAS riser.
Step 2
Install a new SAS riser:
a.
Connect the SAS cables and BBU cable to the new SAS riser. See
Figure 3-10
.
b.
Align the SAS riser with the empty SAS riser connector on the motherboard.
c.
Push down evenly on both ends of the SAS riser until it is fully seated in the motherboard connector.
d.
Ensure that the SAS riser rear panel sits flat against the server back panel opening.
e.
Push the green retaining clip down until it locks over the top of the SAS riser.
f.
Replace the top cover.
g.
Replace the server in the rack, replace cables, and then power on the server by pressing the
Power
button.
Step 3
Restore the RAID configuration on your drives to the new mass storage controller.
