5.2 SCSI Disk Drive Housing
Before removing a SCSI HDD, please be careful to disconnect all the relevant wires/
cables and fans behind the IDE disk drive and the SCSI disk drive housing, as well as
the SCSI mobile trays; this facilitates removal, and reduces risk to the hard drive and
its data. When in doubt, please consult with an experienced technician.
The procedure for taking out the SCSI disk drive housing is as follows:
1. Open the top chassis cover and release the two thumb screws; to pull out the
backplane holder until you can remove the SCSI disk drive housing easily.
2. Disconnect the two fan wires on the alarm board and the three power wires and
the SCSI flat cable on the SCSI backplane.
3. Undo the four screws of the alarm board, and then move it away.
4. Loosen the four screws of the cushions and then carefully take out the SCSI
disk drive housing.

5.3 Wires & Cables of the SCSI Storage
There is one 68-pin SCSI flat cable in the accessory package. This cable is for con-
necting the add-on SCSI RAID card/controller and the SCSI backplane. The power
wires of the dual fans should be connected to the alarm board. The three 4-pin power
connectors on the rear side of the SCSI backplane are for connecting the power
wires from the power supply.
Note! Please be sure to plug these wires and cables in well before you install
any SCSI HDD. When you have to take out the SCSI disk drive housing
from the chassis, please disconnect the wires and cables first.
