Drive Preparation
1. Remove the drive from its protective packaging.
2. Plastic Drive Bezel - If installing a hard drive which is equipped with a plastic front
bezel, remove the drive bezel.
3. SCSI Drive Termination - The last drive on any SCSI channel must have termination
enabled. In most instances, depending upon the cable configuration, termination will
be handled by an external terminator on the DS500 back panel. If using an external
terminator, disable onboard drive termination. In some RAID configurations, onboard
drive termination is mandatory. Refer to the manufacturer's instructions which
accompany the optional equipment for SCSI termination requirements (refer to section
"Connecting the DS500 to a Computer System" for additional SCSI connection
information).
4. SCSI ID Selection and Device Jumper Configuration - Determine the location that
each device will occupy within the DS500 chassis and label each device accordingly.
Locate the SCSI ID select jumper pins on each drive (refer to the device manufacturer's
documentation if necessary, for the location of the SCSI ID pins). Select a unique ID
for each device connected to a single host, and position the SCSI ID jumpers on the
pins according to the device manufacturer's instructions. Label each drive with the
SCSI ID number to facilitate installation.
Carefully select the appropriate SCSI ID number(s) for the installed device(s).
Selecting the same number on different devices may cause unpredictable results and
the computer system may not recognize the installed device(s). I f t he computer system
can not recognize the boot disk, the computer system may fail to properly start-up.
The SCSI ID is an address number (0 through 7 for 8-bit protocol and 0 through 15 for
16-bit protocol) that is assigned to each SCSI device. Each device in the chain must
have a unique SCSI ID number. SCSI ID 7 is usually reserved for the host controller.
If the computer system is already equipped with internal or external SCSI storage
devices, some ID numbers will already be reserved. For instance, if the computer
system came with an internal SCSI hard drive, it may be designated as SCSI device
0 (refer to the computer system documentation for additional information). If the drives
are to be attached to a RAID controller, refer to the RAID controller's documentation
for SCSI ID selection information.
5. If installing 3.5" devices into the DS500, attach the 3.5" adapter brackets (included)
to the drives (Figure 7). The adapter brackets can be attached to the drive with four
(4) #6-32 x 1/4" screws.
6. Connect the 4-pin DC power cable(s) to the power connector(s), located on the rear
of the device(s) (Figure 8).

options that can be used with this product, please visit the StorCase web site at
www.storcase.com.
SCSI Ultra160 Cable Kits
Ultra160 9-Drive Cable Kit
The SCSI Wide Ultra160 Low Voltage Differential (LVD) protocol supports a maximum 160
MByte/sec transfer rate for applications with up to 15 LVD devices, providing that the total
(internal plus external) device-to-host cable length does not exceed 12 meters (approx. 39
feet). The StorCase® Technology Ultra160 9-Drive Cable Kit (P/N DCULTRA160-9KIT), designed to fit the rear panel of the Data Silo® DS500 9-bay tower or rack mount chassis, simplifies
and reduces this Ultra160 cable length limitation.
With the DCULTRA160-9KIT installed within up to two DS500 9-bay chassis, any combination
of up to 15 SCSI Wide Ultra160 devices can be supported on a single Ultra160 channel, allowing
a total maximum external cable length of 12 meters. Without a DCULTRA160-9KIT installed in
each chassis however, the chassis-internal cable lengths between devices must also be
taken into consideration, thus reducing the maximum allowable external cable length available.
The DCULTRA160-9KIT includes a SCSI Ultra160 repeater board with internal and external
SCSI connectors, an internal power splitting cable, and a 9-drive internal Ultra160 ribbon cable
with a crimped-on Ultra160 multi-mode (LVD/Single-Ended) terminator (Figure B-1).
Ultra160 5-Drive Cable Kit
The Ultra160 5-Drive Cable Kit (P/N S90A100) is also designed to fit the rear panel of the DS500
chassis. Two (2) S90A100 cable kits installed within a single DS500 allow for dual-channel
configurations. With the S90A100 kit installed within up to three DS500 9-bay chassis, any
combination of up to 15 SCSI Wide Ultra160 devices can be supported on each Ultra160
channel.
The S90A100 includes a SCSI Ultra160 repeater board with internal and external SCSI connectors, an internal power splitting cable, and a 5-drive internal Ultra160 ribbon cable with a
crimped-on Ultra160 multi-mode (LVD/Single-Ended) terminator.

The installation and removal of a fan module is a fairly easy process with just two (2) thumbscrew
fasteners and one (1) connector. It is not necessary to turn the A/C power off to the DS500
to remove a fan module (the fan is "hot swappable"). The DS500 includes an additional blank
filler panel for the fan module which contains I/O cutouts with blank inserts. If removing a fan
module, replace it with this filler panel to insure proper cooling to the DS500. The filler panel inserts
can optionally be replaced with two (2) sets of I/O connectors to provide additional host I/O

Replacing a Power Supply
The DS500 comes equipped with two (2) power supply units. This allows the DS500 chassis
to run in Shared Mode, thus enabling both power supplies to operate at a reduced wattage
and lower operating temperature. If one power supply should fail, the other will carry the full
load without interruption.
Figure B-8: Replacing a Power Supply
1. To remove the power supply to be replaced, loosen the thumbscrew fasteners and
slide it out.
2. Slide the new power supply into place through the DS500 rear panel by aligning the
guides of the power supply module with the slots in the chassis back panel. Make
certain that no wires are pinched between the back panel and the power supply
module.
3. Push the power supply tightly against the DS500 chassis back panel and tighten the
thumbscrew fasteners.
4. Install the power cable.
5. Turn on A/C power.
6. If replacing a failed power supply and the error light is still flashing, press the reset
button on the front panel to turn it off.
