Replacing an IDE Backplane Assembly

CRU Replacement Procedures 5-37

Replacing an IDE Backplane Assembly

The IDE backplane assembly is a small circuit board located behind the CD/DVD drive

bay. You need to remove the CD or DVD drive to replace the assembly.

Estimated time: Fifteen minutes.

Tools: ESD strap and #1 Phillips head screwdriver (shaft at least 6 inches long, less

3/16 inch wide).

1. Remove the CPU-I/O enclosure.

2. With the enclosure on a stable, flat surface, remove the enclosure cover.

3. Remove the CD or DVD drive as described in “Removing a CD or DVD Drive” on

page 5-35.

4. Remove the IDE power cable (number 4 in Figure 5-23) from the assembly.

NOTE

Pull on the connector (not the wires) to disconnect the

power cable.

5. Remove the IDE ribbon cable from its retaining clip, then remove the IDE ribbon

cable from the IDE backplane assembly by gently pulling back on both connector

levers at the same time (number 3 in Figure 5-23).

NOTE

Pull on the connector levers (not the ribbon cable) to

release the IDE ribbon cable. You cannot release the

cable until both levers are disengaged.

6. Push the IDE power cable and ribbon cable aside.

7. Remove the two screws that hold the assembly in place.

To reach the screws, insert an extra long screwdriver into the slot for the CD or DVD

drive and feed it through the screw holes at the rear of the slot (Figure 5-24).

8. Remove the IDE backplane assembly from the enclosure. Separate the plastic

insulator (number 2 in Figure 5-24) from the assembly and save it for the new

assembly.

Set the old assembly aside for repacking. See “Repacking CRUs” on page 4-3.
