5. To install the new assembly, connect the ribbon cable connector to the rear of the
assembly.
6. Align the assembly with the bay opening and press in firmly on both corners of
the assembly until the latch clicks into place.
As you insert the assembly, pull the excess cable back in through the openings in the
chassis.
7. Replace the cable service loop in the clip on the right wall of the server chassis.
Note – To avoid possible electrical emission interference, do not leave the ribbon
cable folded up under the assembly. Instead, retract the slack cable and secure it
with the clip on the side of the chassis.
8. Before re-installing the cover on the server, check the routing of all cables for
obstructions.
4.5.4 CPU Card
This card is an optional daughter-board that slides into the front of the server.
Note – This procedure can be done with the server mounted in a rack. If it is in a
rack, pull the server forward from the rack about 3 inches (76 mm) to provide
clearance before opening the CPU card door.
1. Power off the server, including any attached peripherals, and disconnect the
server from the electrical outlet. If your server includes two power supplies,
ensure that both power cords are disconnected from the electrical outlet.
Refer to “Powering Off the Server and Removing the Cover” on page 4-2.
It is not necessary to remove the cover for this procedure.
2. Remove the front bezel from the server by pressing in on the rubberized buttons
on each side of the bezel, then swinging the bezel top downward (see
FIGURE 4-15).
