Replacing a Rear-Loading Drive Backplane Assembly
Although all server versions have the rear-drive cage installed as part of the chassis at the factory, you can
use it only if you have ordered or installed a rear backplane.
Step 1 Shut down and remove power from the server as described in
on page 39.
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 from the server as described in
Step 4 Remove any existing rear drive backplane assembly:
a) Remove any drives from the existing rear drive backplane and set them aside.
b) Remove the fan from the rear backplane assembly. Pinch the green finger-grips on the top of the fan and then lift
straight up.
c) Disconnect the CONN REAR cable from the backplane.
d) Lift the hinged rear backplane retainer on the top of the rear backplane cage. This metal retainer is marked blue.
e) Grasp the black plastic fingergrip on the rear backplane and lift the backplane straight up to remove it from the
motherboard socket and cage.
Step 5 Install a new rear backplane or kit:
a) Grasp the new rear backplane by the black plastic fingergrip on its frame.
b) Lower the new backplane into the guide channels on the cage until its edge connector touches the socket on the
motherboard.
c) Push down on the top of the backplane until its securing clips click and the edge connector is firmly seated in the
motherboard socket.
d) Close the hinged rear backplane retainer on the top of the cage.
e) Connect the CONN REAR cable from your SAS controller or PCIe riser to the socket on the backplane.
f) Install the rear backplane fan. With the arrows on top of the fan pointing toward the rear, lower the fan's connector
over the socket and align the guides on the fan into the channels that are on the power supply cage.
g) Push down on the top of the fan until it clicks.
h) Install drives to the rear bays.
