to the drive(s) and to protect the finish of the chassis. Refer to the documentation provided
with the drive(s) to be installed to identify appropriate connectors, jumpers, and terminators
on each. A #2 Phillips and a flat blade screwdriver will be required.

Removing the Cover

CAUTION: Remove ALL power from the DS400 before removing the cover. The Data Silo

The physical process of installing drives into the DS400 will involve removing the cable access
cover (and side panels on tower models), fastening the drive(s) into the drive mounting bracket,
connecting the power and I/O cables to the drive(s), and replacing the chassis cover.

contains NO USER SERVICEABLE PARTS inside the unit.

1. Unpack the DS400, or if already installed in a rack cabinet, unplug it and verify that

8 Installation

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 DS400 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 DS400 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 DS400 chassis and label each device accordingly.
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.

Selecting the same SCSI ID number(s) on different devices may cause unpredictable
results and the computer system may not recognize the installed device(s). If the
computer system can not recognize the boot disk, the computer system may fail to
properly start up.

The SCSI ID is an address number (0-7 for 8-bit protocol and 0-15 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 DS400, attach the 3.5 " adapter brackets (included)
to the drives (Figure 6). The adapter brackets can be attached to the drive with four
(4) #6-32 Phillips screws.

6. Connect the 4-pin DC power cable(s) to the power connector(s), located on the rear
of the device(s) (Figure 7).

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.

Installing the Replacement Power Supply

A power supply LED indicator is located on DS400 back panel (Figure C-8). When illuminated,
this LED indicates that the power supply is functioning normally. If this indicator fails to illuminate
when the chassis power is on, it is an indication that a problem with the power supply has
occurred. If this is the case, replace the power supply module.

A diagnostic connector (3.00mm Molex - P/N 43020) located on the DS400 back panel, provides
system operating status. A 4.5 to 5V reading indicates normal operating status. A reading
below 4.5 to 5V indicates a system malfunction.

Follow the steps below to replace the DS400 power supply.

CAUTION: Disconnect all power from the DS400 before opening the chassis.

1. Verify that all power is off and that the cables have been disconnected from the DS400
chassis.

2. Remove the cable access cover as shown in Figure B-8.
