Data Silo® DS50

Packaging Materials

The Kingston Technology Data Silo® external expansion chassis is shipped in a container
designed to provide protection and prevent damage during shipment. The Data Silo was
carefully inspected before and during the packing procedure at the factory. Evidence of any
damage to the Data Silo should be reported to the shipper immediately.

If the wrong Data Silo model has been received, please call Kingston's Storage Product
Division at [phone]. A staff member will give you a Return Material Authorization
(RMA) number to facilitate processing. Kingston cannot accept returns which do not
display an RMA number on the outside of the package. Return the unit with all the original
packing materials.

Before removing any component from its packaging, discharge any static electricity by
touching a properly grounded metal object.

Serial Number

The Data Silo is labeled with a serial number. This number must be reported to the
Kingston Customer Service Representative in order to receive a Return Material Authoriza­tion (RMA) for warranty claims. Locate the serial number label and record the number in
the space provided below.

2 Introduction

General Description

The Kingston Technology Data Silo® DS50 series of stand-alone expansion chassis provide
rugged and reliable housing for 3.5 inch half-height SCSI storage devices.

The Data Silo DS50 is available in single and dual bay configurations (Figure 1). Each
chassis is constructed of rugged steel and is equipped with an auto-ranging power supply,
power-on LED, highly-rated cooling fan, and all necessary internal wiring and mounting
hardware. Removable front filler panel(s) facilitate the mounting of either fixed or removable
media devices.

The Data Silo is available with 50-pin SCSI 2 or 68-pin SCSI 3 interfaces. Both Data Silo
models come with externally mounted SCSI ID selection switch(es) for easy unit ID
selection.

Introduction 3

This User's Guide describes the steps required for installing drive(s) into the Data Silo
DS50 external expansion chassis. The illustrations and instructions contained in this
manual are generally representative of all Data Silo DS50 models. Your Data Silo may
differ slightly from the illustrations shown. Although each Data Silo model contains different
drive bay or I/O interface configurations, the installation process is basically the same for
all models.

This guide is intended to supplement documentation provided with the host computer
system, the operating system, and the drive to be installed within the Data Silo. Figure 2
below illustrates a typical drive installation into a Data Silo DS50 external expansion
chassis.

DATA SILO INSTALLATION
Installing the Drive(s) into the Data Silo

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 during
this procedure.

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 - Disable SCSI termination from the drive. Refer to the
documentation provided by the drive manufacturer for the location of these
terminators or jumpers. Termination is provided by an external terminator on the
Data Silo rear panel. External active termination is recommended for best SCSI
performance (terminator not included with the Data Silo).

4. SCSI Drive ID Select Jumpers - Locate the SCSI ID select jumper pins on the
drive, and remove any jumpers on these pins. The Data Silo SCSI ID cable will be
attached to these pins on each drive (Figures 6 and 7).

5. SCSI ID Cable - Each Data Silo is supplied with one SCSI ID select cable per drive
bay. The ID cable permits external unit ID selection via a small switch located on
the rear panel of the Data Silo (Figure 4). One end of this cable attaches to the
drive SCSI ID pins and the other end attaches to the Data Silo unit ID select
switch. One end of this cable has a single connector with 1.25mm pin spacing.
The other end contains individual 2mm connectors. This cable can be used with
drives that have either 2mm or 1.25mm pin configurations by simply reversing the
cable. The Data Silo unit select switch contains connectors that except either end
of this cable.

NOTE: Depending upon the model, the Data Silo uses one of two different types of

SCSI ID select switches. The first type of switch utilizes a single connector with
.1" pin spacing and has a matching SCSI ID cable designed to attach to 2mm
drive pins. The other type of SCSI ID switch has 2 connectors with a reversing
SCSI ID cable that will allow either end of the cable to be attached to the drive.
The second type of switch will attach to either 2mm or 1.25mm drive pins
(Figures 6 and 7).

DS50 User's Guide - Rev. B00 Kingston Technology Company

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

The single black wire plugs into the drive pin used to select ID0, the brown wire
plugs into the drive pin for ID1, the red/black wire plugs into the drive pin for ID2.
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

(Figure 7).

The single black wire plugs into the drive pin used to select ID0, the brown wire
plugs into the drive pin for ID1, the red/black wire plugs into the drive pin for ID2
and the orange wire plugs into the drive pin to select ID3.

In most cases, the drive manufacturer labels each pair of SCSI ID select pins in

Drive Installation

Removal of the drive mounting bracket from the DS50 chassis is required in order to fasten
the drive(s) into the bracket. The entire drive/bracket assembly can then be reinstalled into
the DS50 chassis.

1. Turn the Data Silo over and place it on a soft clean surface, so that the bottom is
facing upward.

2. Loosen but do not remove the three (3) screws that secure the drive mounting
bracket to the Data Silo chassis (Figure 9).

3. Place the Data Silo in an upright position so that it rests on its four rubber feet.

4. Remove the drive mounting bracket from the chassis by sliding it toward the
chassis back panel, then lifting upward (Figure 10).

Selecting the SCSI ID Number

The SCSI ID is an address number (0 through 7 for 8-bit protocol and 0 through 15 for 16­bit protocol) that is assigned to each SCSI device. In a SCSI daisy-chain, 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.

The Data Silo SCSI ID selection switch(es) is located on the rear panel of the chassis
enclosure (Figure 14). Depending upon the Data Silo model and interface, there are three
(3) different SCSI selection switches available. Two types of rotating switches that can be
adjusted with the provided adjustment tool. The other switch has a push button selector
that can be adjusted with the tip of a pen or straightened paper clip.

Carefully select the appropriate SCSI ID number(s) for the installed devices(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.
