Chapter 3 Maintaining the Server
Installing or Replacing Server Components
Replacing a SATA Interposer Board
The server uses a SATA interposer board and cable to connect the embedded RAID (PCH SATA)
controller on the motherboard to the drive backplane. See
Figure 3-18 for the socket location.
Note
The SATA interposer board and embedded RAID can be used only with the SFF, 8-drive backplane
version of the server. It does not operate with an expander. You cannot use the embedded RAID
controller and a hardware RAID controller card at the same time.
See Embedded SATA RAID Controller, page C-10 for more information about using the embedded
RAID controller and options.
Step 1
Power off the server as described in the Shutting Down and Powering Off the Server, page 3-9 .
Step 2 Slide the server out the front of the rack far enough so that you can remove the top cover. 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.
Step 3
Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-10 .
Step 4 Remove the plastic air baffle that sits over the CPUs to gain access to the interposer cables.
Step 5
Remove PCIe riser 1 from the server to provide clearance. See Replacing a PCIe Riser, page 3-47 .
Step 6 Remove any existing PCH SATA interposer board:
a.
Disconnect both cable connectors from the interposer board.
b. Lift straight up on the board to remove it from its motherboard socket.
Step 7
Install a new interposer board and cables:
Note
The required Y-cable and SATA interposer board are bundled as
UCSC-IP-PCH-C240M4=.
a.
Align the board with the socket, and then gently press down on both top corners to seat it evenly.
b. Connect the single mini-SAS HD cable connector to the single connector on the backplane.
c.
Route the cables through the plastic clips on the chassis wall.
d. Connect PORT A and PORT B cable connectors to their corresponding connectors on the new
interposer board.
Step 8
Replace PCIe riser 1 to the server.
Step 9 Replace the air baffle.
Step 10
Replace the top cover.
Step 11 Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.
