7. Disconnect the SAS cables from the internal HBA, and then carefully lift the
SAS cables that you disconnected from the internal HBA out of the cable
trough.
8. Remove the server mid-wall [5].
a. Using a No. 2 Phillips screwdriver, loosen the four green captive screws that
secure the mid-wall to the server chassis.
b. Lift the mid-wall up slightly and pull in toward the front of the server to
disengage it from the raised mushroom-shaped standoffs that are located on
the server chassis sidewall (one on each end of the mid-wall).
c. Place the mid-wall, DVD cable, and SAS cables toward the front of the server
and out of the way of the motherboard.
9. Remove the motherboard from the server chassis [6].
a. Grasp the middle of the air duct in the front and back and slide the
motherboard toward the front of the server and lift it slightly to disengage it
from the six mushroom-shaped standoffs that are located on the server
chassis under the motherboard [6].
b. Lift the motherboard out of the server chassis and place it on an antistatic
mat, and next to the replacement motherboard [6].
10. Remove the internal USB flash drives from the motherboard and install them on
the replacement motherboard.
For instructions, see
11. Remove the DDR3 DIMMs from the motherboard and install them on the
replacement motherboard.
For instructions, see
Note – Install the DDR3 DIMMs only in the sockets (connectors) that correspond to
the sockets from which they were removed. Performing a one-to-one replacement of
the DIMMs significantly reduces the possibility that the DIMMs will be installed in
the wrong sockets. If you do not reinstall the DIMMs in the same sockets, server
performance might suffer and some DIMMs might not be used by the server.
12. Remove the processors from the faulty motherboard.
For instructions, see
13. Remove the processor socket covers from the replacement motherboard and
install the processors.
