Installing the System/Backplane Board Assembly

CAUTION:

See your System Information Guide for complete information about safety precautions,

working inside the computer, and protecting against electrostatic discharge.

NOTE:

It is not necessary to remove the hard drives or the CD/diskette drive from the system during this

procedure.

To install the system board/backplane board assembly, perform the following steps:

Connect the four-conductor power cable to the back of the backplane (connector U3). Secure

this connector with a plastic cable tie to the backplane.

Connect the system board to the backplane board. See Figure 1-2.

NOTICE:

Use a screw only in the center screw hole to secure the system board/backplane board to the

chassis.

Using one of the three Phillips screws removed in step 21 of the board removal procedure,

secure the system board/backplane board to the chassis using the center screw hole (see

Figure 1-3). Discard the other two screws.
