SCSI Hard Disk Drives
The system comes with three externally accessible SCA hard drive
bays on each side to make a total of six.
Hot-Swap Drive Tray
In each of the HDD bays is a hot-swap
tray for mounting a hard disk drive. Flip
open the tray levers to release the tray,
then slide the tray out of the chassis.
Tray Levers
SCSI HDD Mounting
Place the SCSI hard disk drive to
the hot-swap tray and secure it
with four screws as shown.
HDD Installation
After the drive is secured to the tray, carefully
insert the drive into the bay, then push
the levers back in place.
IMPORTANT
Make sure that the SCSI cable is connected to the motherboard
and the backplane. Refer to the section “Connecting Cables”.

CD-ROM Drive
CD-ROM Installation
Place the CD-ROM drive in its bay
and slide it inward.
Secure the drive to the chassis with
the four levers as indicated by the
arrows. Connect the IDE and
power cables to the CD-ROM.
Floppy Drive
The system comes with the floppy drive already installed. Refer to
this section when you need to replace the floppy drive.
Floppy Drive Mounting
Mount the two brackets to the
floppy drive and secure it with four
screws and connect the white
ribbon cable (compact version of
the standard gray floppy drive
cable). The white ribbon cable
already includes power so there is
no place for a separate floppy
power connector.

Power Supply Removal
The power supply is redundant and
hot-swappable. Meaning that you
can remove one module while the
server is powered ON.
To remove a power supply module,
squeeze the handle and push
down to eject the individual power
supply module. Then carefully pull
out the power supply module.
