To replace a SCSI disk drive:
Each SCSI disk drive is placed in a hard drive carrier cartridge that is
accessible from the front and is equipped with a lock. The lock secures
the cartridge in place and serves as an ON/OFF switch for the power to
the drive. To replace a disk drive, you must have the hard drive carrier
key to unlock the drive.
Important:
The two SCSI drives in the system are configured in a
RAID 1 configuration. Each requires a unique drive
identifier.
Before setting a drive in a carrier, the top SCSI drive should
be set to 0 on the 16-position switch selector (0-F). The
bottom SCSI drive should be set to 1.
The dialer-type selector switch is located at the back of the
cartridge. To change the SCSI ID, use a small flat-head
screwdriver to rotate the arrow to point to the desired SCSI
ID number.
1.
Insert the hard drive carrier key into the lock on the cartridge.
2.
Pushing in on the key, turn the key 90 degrees counterclockwise to
unlock the drive.
3.
Grasp the handle on the drive bay and pull drive carrier completely
out of the unit.
4.
Pry loose the bottom carrier cover using the supplied tool or a flat-
head screwdriver.
5.
Remove two 6-32 x 3/8” screws from each side of the carrier and
carefully lift the drive out of carrier.
6.
Remove 3 connectors (power, SCSI, and CRU) from the drive.
7.
To install a new drive, reverse the steps in this procedure.
To replace a power supply:
1.
Unplug the AC power cord from the power supply.
2.
Remove the middle screw closest to the handle on each side.
3.
Grasp the handle and remove the power supply.
4.
To install a new power supply, reverse the steps in this procedure.
