Installing Drives 7-7
4. Remove the expansion-card cage as instructed in
“Removing and Replacing the Expansion-Card
Cage” in Chapter 5.
5. Remove the hard-disk drive bracket from the
chassis.
If a hard-disk drive is already installed on the drive
bracket and you are replacing it, disconnect the DC
power cable and EIDE cable from the drive.
Loosen the captive screw that secures the hard-disk
drive bracket to the chassis (see Figure 7-11). Then
rotate the bracket upward and lift it out of the
chassis.
Detach the hard-disk drive from the bracket by
removing the four screws.

Bracket
6. Secure the drive bracket to the new drive.
Turn the drive upside down and locate the four screw
holes around its perimeter. Orient the drive bracket
so that the end labeled “CONNECTOR” faces the
side of the drive containing the interface and power
connectors. Place the bracket on the drive and secure
it with four screws (see Figure 7-12).

the Bracket
7. Reinstall the hard-disk drive/bracket assembly in
the chassis.
Grasp the bracket by the tab containing the captive
screw and hold the bracket at a 45-degree angle to the
chassis floor. Align the two tabs on the other side of
the bracket with the score marks on the chassis floor.
Insert the two tabs into the slots in the chassis floor
divider, and rotate the assembly downward. Then
tighten the captive screw until the bracket is securely
fastened to the chassis floor (see Figure 7-11).
8. Connect one end of the EIDE cable to the 40-pin
interface connector on the back of the hard-disk
drive (see Figure 7-13).
The cable is keyed so that the colored edge of the
EIDE cable lines up with the pin-1 end of the inter-
face connector.

CAUTION: You must match the colored strip
on the EIDE cable with pin 1 on the drive’s
interface connector to avoid possible damage
to your system.
