GeneralDescription

The StorCase Technology Data Silo® DS351 expansion chassis provides rugged and reliable
housing for SCSI storage devices. The DS351 is designed to support 3.5" and 5.25" form factor,
full-height, half-height, and low profile (1" high) removable media devices. The DS351 can
house Data Express® removable drive enclosures as well.

The DS351 is available in a rack mount, quad (4) bay configuration (Figure 1). Each chassis
is constructed of rugged steel and is equipped with two (2) 65W auto-ranging power supplies,
chassis status LED, three (3) high-speed cooling fans, and all necessary drive mounting
hardware.

The DS351 can support single or dual-host 50-pin Microminiature (HD50), 68-pin High Density,
and 68-pin VHDCI (used for Ultra2 and Ultra160) interfaces. Internal cables for the DS351 are
not included and must be ordered separately, providing either two (2) or four (4) drive daisy­chain connections. Contac your StorCase dealer for these and other available cable options.

INSTALLATION

Installing the Drive(s) into the DS351

While performing the steps in this section, work on a soft surface to prevent excessive shock
to the drive(s) being installed. Also refer to the manufacturer's documentation provided with
the drive(s). A #2 Phillips and a flat blade screwdriver will be required.

Removing the Access Panel

WARNING: Remove ALL power from the DS351 before removing the access panel. The

1. Unplug the DS351 and verify that ALL cables have been disconnected.

2. Place the DS351 on a soft clean surface to protect the finish of the chassis.

3. Remove the eight (8) screws located on the top of the unit (Figure 5).

4. Remove access panel by carefully lifting the front of the panel and sliding (forward)

5. To reinstall panel, simply reverse the above mentioned steps.

DS351 contains NO USER SERVICEABLE PARTS inside the unit.

StorCase Technology, Inc. DS351 User's Guide - Rev. B02

Installation 7

Drive Preparation

1. Remove the drive from its protective packaging.

2. SCSI Drive Termination - The last drive on any SCSI channel must have termination

enabled. In most instances, depending upon cable configuration, termination will be
handled by an external terminator on the DS351 back panel. If using an external
terminator, disable onboard termination. Refer to the documentation provided by the
drive manufacturer for the location of these terminators or jumpers. External active
termination is recommended for best SCSI performance (terminator not included with
the DS351).

Removing the Drive Bracket

NOTE: Removal of the access panel (Figure 5) and drive bracket (Figure 6) is required in

order to install the drive(s). Once the drive(s) are installed into the bracket the entire
drive/bracket assembly can then be installed into the chassis.

1. Remove the access panel (Figure 5).

2. Remove the four (4) screws securing the drive bracket to the chassis (Figure 6).

3. Remove the drive bracket from the chassis by carefully lifting the rear of the bracket
out first.

5. Connect the I/O cable(s) to the drive(s). Verify that the Pin 1 indicator on the cable
is properly aligned (refer to the drive manufacturer's documentation for more in­formation).

6. Connect the 4-pin DC power cable(s) from the DS351 power strip to the drive(s)
(Figure 10).

7. Reinstall the access panel and fasten all screws.

8. Connect the AC power cable to the DS351 and turn ON power. Should there be any

unusual sound, turn the DS351 OFF immediately. Disconnect the power cable and
remove the access panel to locate the source of the problem.

Installation 11

Connecting the DS351 to the Computer System

If the DS351 is the last device in a SCSI daisy chain, it will require the appropriate termination
(Figures 11 & 12).

The DS351 can be configured with two (2) external rear panel SCSI I/O connectors designed
for a single host (single-port) connection, or four (4) rear panel SCSI I/O connectors designed
for dual host (dual-port) connection.

The four (4) connector (dual-port) configuration permits two (2) separate host/daisy-chain
connections; some drives within the DS351 chassis can be connected to one host/daisy­chain, and the remainder of the devices can be connected to a second host/daisy-chain (Figure

12).

Figure 11: Typical Daisy-Chain Connections

DS351 User's Guide - Rev. B02 StorCase Technology, Inc.

12 Installation

Figure 12: Dual Host Daisy-Chain Connection

StorCase Technology, Inc. DS351 User's Guide - Rev. B02

Installation 13

Selecting the SCSI ID Number

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).

Four (4) SCSI ID selection switches are located on the front panel of the DS351 enclosure
(Figures 3 & 13). These rotating switches can be adjusted with the provided alignment tool.

Carefully select the appropriate SCSI ID number(s) for the installed device(s). Note that some
switch settings may be invalid for your interface type. Selecting an invalid ID number, or
selecting the same number 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.

Figure 13: SCSI ID Selection Switch

DS351 User's Guide - Rev. B02 StorCase Technology, Inc.

14 Installation

IF INSTALLING AN 8-BIT SCSI DEVICE:

The unit ID cable contains black, brown, red/black, and orange wires. Attach three
(3) connectors from the SCSI ID select cable to the appropriate 2mm drive pins (Figure

14). The fourth (orange) wire is not used for the 8-bit installation.

The single black wire plugs into the drive pin used to select ID1, the brown wire plugs
into the drive pin for ID2, the red/black wire plugs into the drive pin for ID4. The orange
wire is not used for this interface.

In most cases, the drive manufacturer labels each pair of SCSI ID select pins in
significant bit order (0, 1 and 2). One row of drive pins is the signal row, and one row
is designated for ground (refer to the drive manufacturer's documentation for specific
pin configurations).

The Data Silo ID select cable provides 2mm, 2-conductor drive connectors. A single
wire attaches to one side of each connector (with the exception of the red/black
connector). The cable side of each connector must align with the signal pin on the
drive. On the red/black connector, the red wire aligns with the signal pin on the drive
and the black wire aligns with the ground pin.

NOTE: Some versions of the Data Silo have a reversible ID select cable. This cable may

be attached to either 2mm or 1.25mm drive pins.

IF INSTALLING A 16-BIT SCSI DEVICE:

The unit ID cable contains black, brown, red/black, and orange wires. Attach four

15).

The single black wire plugs into the drive pin used to select ID1, the brown wire plugs
into the drive pin for ID2, the red/black wire plugs into the drive pin for ID4 and the
orange wire plugs into the drive pin to select ID8.

In most cases, the drive manufacturer labels each pair of SCSI ID select pins in
significant bit order (0, 1 and 2). One row of drive pins is the signal row, and one row
is designated for ground (refer to the drive manufacturer's documentation for specific
