This chassis kit supports an ASUS motherboard that measures 12x13
inches (30.5 x 33 cm) for SCSI models, or 12x12 inches (30.5 x 30.5 cm)
for IDE models. Motherboards of smaller sizes will fit into the system
chassis. Refer to the motherboard user guide for more information on the
system requirements.
13 in (33 cm)
Make sure that the motherboard you intend to install into the chassis
does not exceed the maximum specified dimensions. Otherwise, it will
not fit into the chassis.

Installing 5.25-inch drives
If you have previously used and powered up the system, and that it
may be connected to an AC power source, make sure to unplug the
power cable before installing or removing any system components.
Failure to do so may cause severe damage to the motherboard and
other system components!
Three 5.25-inch drive bays are
located on the upper front part of the
chassis. A CD-ROM drive that comes
standard with the system package
occupies the uppermost bay (labeled
1). The two lower bays (labeled 2 and
3) are available for additional
5.25-inch devices.

front panel assembly (front bezel and front panel cover). The front
panel assembly is attached to the chassis through four hooked tabs
on the left side and four hinge-like tabs on the right side.
To remove the front panel assembly:
1. Use a flat-head screwdriver to detach the hooked tabs from the left
side of the front panel.

Installing hard disk drives
The six hard disk drive (HDD) bays on the front panel include externally
removable trays for mounting either SCSI or IDE 3.5-inch hard disk drives.
You can access the drive trays by simply opening the the front bezel.
1. SCSI and IDE drive trays differ in size and structure. Make sure of
the type of HDD trays that came with your chassis before buying
hard disks.
2. If your motherboard does not have an onboard SCSI interface, you
need to install a SCSI expansion card into one of the PCI slots.
Use a SCSI cable to connect the card to the SCSI backplane board
to which the hard disks are connected.
2.5.1 SCSI hard disk
To install a SCSI hard disk drive:
1. Release an HDD tray by
pushing the tray lock upward
2. Pull down the tray lever until the
tray pops out slightly, indicating
that it is released.

2.6.2 Installing a long expansion card
If you are installing a long expansion card, such as some types of RAID
cards, use the plastic card support located near the front of the chassis
(under the backplane board) to keep the expansion cards firmly seated on
the slots. This card support has individual card guides that correspond to
each expansion slot.
Plastic long-card support
To install a long expansion card:
1. Position the expansion card above the PCI slot that you wish to use.
2. Insert one end of the card to the card guide opposite the PCI slot, and
align the bracket end of the card to the expansion slot on the rear
panel.
3. Slide in the card down until it is properly seated on the slot.

2.7.3 Roller wheels
The chassis comes with four roller wheels for convenient transport. Each
wheel has a brake lock to stabilize the chassis in place.
To remove the chassis wheels:
1. Lay the chassis in its side.
2. Use a Phillips screwdriver to remove the screws that secure the
wheels to the bottom of the chassis.

Remove the chassis roller wheels if you wish to mount the system to a
rack. Refer to the Rackmount Kit manual for more information.

2.7.4 Power supply modules
The redundant power model has two power supply modules. These hot
swap power modules can be removed or installed while the system is
powered ON. Only one power module is necessary to provide power to the
system. However, it is recommended to have two redundant power supply
modules. In case one of the power modules fails, the other one keeps
providing sufficient power to the system. This eliminates system down time
and data loss. When two power supply modules are installed, the task of
providing power to the server is shared.
To remove the redundant power supply module:
1. Remove the screw that secures the power module to the chassis.
2. Press down the rubber lever to release the power module.
3. Pull out the power module from the chassis.

Connecting the cables
2.8.1 Motherboard connections
The chassis includes power and signal cables that you need to connect to
the motherboard, SCSI backplane, and to the devices that you will install.
Most of the cables for the chassis kit are already connected upon
shipment. When installing system devices and connecting cables,
make sure that all cables are routed properly for better system stability
and performance. Refer to the picture below when arranging cables.

2.8.2 SCSI backplane connections
The SCSI backplane has six 68-pin SCSI connectors to support SCA SCSI
hard disks. The backplane design incorporates a hot-swap feature to allow
easy connection or removal of SCSI hard disks. The LED connectors on
the backplane connect to the front panel LEDs to indicate HDD access,
HDD failure, thermal failure, or fan failure.

Troubleshooting
Appendix
A-1
A.1
Simple fixes
Some problems that you may encounter are not due to defects on the
system or the components. These problems only requires simple
troubleshooting actions that you can perform by yourself.
Problem
A-2
Action
The power LED on the server or
on the monitor do not light up
1. Check the power cable
connection on the system rear
panel if properly connected.
2. Make sure that the power
cables are connected to a
grounded power outlet.
The keyboard does not work
Check the keyboard cable if
properly connected to the
keyboard port.
The mouse does not work
Check the mouse cable if properly
connected to the mouse port.
The system does not perform
power-on self tests (POST) after
it was turned on
1. Check the memory modules
and make sure you installed
the DIMMs the system
supports.
2. Make sure that the DIMMs are
properly installed on the
sockets.
Appendix: Troubleshooting
Problem
Action
The system continuously beeps
after it was turned on
1. Check the memory modules
and make sure you installed
the DIMMs the system
supports.
2. Make sure that the DIMMs are
properly installed on the
sockets.
3. Check if it has a VGA ouput.
The message “Non-system disk
or disk error” appears
1. Check if a bootable HDD is
active.
2. Check if the HDDs are
properly installed. On SCSI
models, make sure that the
cables are properly connected
to the SCSI connectors on the
backplane.
Network connection not
available
1. Make sure that the network
cable is connected to the
RJ-45 port on the rear panel.
2. Make sure that you have
installed the LAN drivers from
the support CD.
