Figure 4-8. Hard-Disk Drive Removal
The hard-disk drives are mounted inside a hard-disk drive bracket. The hard-
disk drive bracket must be removed before a hard-disk drive can be removed.
To remove a hard-disk drive, follow these steps:
1. Lay the computer on its right side.
2. Disconnect the DC power cable and the SCSI interface cable from the
back of each hard-disk drive installed in the hard-disk drive bracket.
3. Remove the four mounting screws that attach the hard-disk drive
bracket to the front of the computer chassis.
4. Slide the hard-disk drive bracket toward the back of the computer until
the alignment tabs disengage from the alignment rails; then lift it out of
the computer.
5. Remove the four hard-disk drive mounting screws from the hard-disk
drive; then slide the drive out of the bracket.
6. Record the setting of the SCSI address jumpers and SCSI bus termina-
tion jumper.
When you reinstall a hard-disk drive, set the SCSI address jumpers and the
SCSI bus termination jumper to the settings you recorded. Be sure you position
the hard-disk drive against the side and back tabs inside the hard-disk drive
bracket (the mounting holes in the hard-disk drive bracket align with the screw
holes in the hard-disk drive).
