3. Pull the drive halfway out to access the drive cables (Figure 9-28).
4. Disconnect the cables from the drive.
5. Remove the drive.
NOTE: The expansion base comes from the factory with blank panels covering
the openings to the drive bays. If no drive is to be reinstalled in
the drive bay, cover the opening by installing the blank panel with
the two drive-mounting screws.
Installing a Drive

drive. Remember to install the drive upside down, since the drive cages are 
upside down during this procedure. In addition, refer to the drive 
manufacturers installation manual for specific instructions and
precautions for replacing a drive. 
The drive bays are designated as drive positions 1 [1] and 2 [2] 
(Figure 9-29). 
NOTE: Internal SCSI-2 drives must be installed in drive position 2 to usethe SCSI-2 signal cable included with the expansion base. Refer to

Installing an Integrated Drive Electronics (IDE) Hard Drive 
IMPORTANT: MS-DOS 6 or higher (5.0 or higher as published by Compaq) isrequired to use an optional IDE hard drive in the expansion 
base. When using a previous version of MS-DOS, the computer 
does not recognize the optional IDE hard drive.
The expansion base has a hard drive interface for an IDE drive (which has a 
built-in controller). There are special procedures for configuring the 
system (computer, drive, and expansion base) when...

The drive power cable [3] is a daisy chain type that can connect to either
one or two drives and comes preinstalled on the vertical circuit board. The
IDE hard drive signal cable [1], the SCSI-2 cable [2], and the tae/diskette
drive signal cable [4] come with the expansion base, but are not
preinstalled (Figure 9-31).
Each cable has a printed description, a Compaq spare part number, and a

Replacing the Drive Cage
IMPORTANT: To prevent the top cover from bowing and causing interference
during docking and undocking, the drive cage spacer must be
properly installed when replacing the drive cage.
To replace the drive cage, complete the following steps:
1. Place the drive cage(s) in position (Figure 9-33).
2. Replace the drive cage screws, but do not tighten them (Figure 9-33). 

3. If the other drive cage was not removed, loosen its screws.
4. Slide both drive cages toward the center of the top cover as much as the
screw holes allow (Figure 9-34). 

5. Tighten the screws.
6. Place the first end of the drive spacer [1] into the slot [2] of the
first drive cage (Figure 9-35). 

7. Flex the top cover of the expansion base downward [1] to slightly widen
the gap between the drive cages (Figure 9-36).
8. While the top cover is flexed, place the other end of the drive cage
spacer [2] into the slot on the other drive cage [3], and release the
tension on the top cover (Figure 9-36).
