INSTALLATION

InstallingtheDriveintotheCarrier

Preparation

While performing the steps in this section, work on a soft surface to prevent excessive shock
to the drive being installed. Also refer to the manufacturer's documentation provided with the
drive.

NOTE: A #2 Phillips screwdriver will be required during this procedure.

1. Remove the drive from its protective packaging.

2. Plastic Drive Bezel: If the drive to install is equipped with a plastic front bezel,

remove it.

3. SCSI Drive Termination: Disable or remove the termination resistor packs

from the drive. Termination is performed by an external terminator in the
DE300i-SW receiving frame (Figure 5). Refer to the documentation provided by
the drive manufacturer for the location of these terminators or jumpers.

4. SCSI Drive ID Select Jumpers: Locate the SCSI ID select jumper positions on

the drive, and remove any jumper plugs in this area. The SCSI ID cable will be
installed into this section of each drive (Figure 6).

5. SCSI ID Cable: Each DE300i-SW carrier is supplied with one (1) 5-wire cable.

This cable carries the SCSI ID signal between the drive and the carrier. The signal
is then transferred to/from the receiving frame via the carrier and receiving frame
mating connectors. The ID cable permits easy unit ID selection via a small switch
located on the inside of the receiving frame (Figure 10). The cable is designed
to connect to drives with 2mm ID select connectors. Attach five (5) connectors
from the carrier SCSI unit ID cable to the appropriate drive pins (Figure 7).

The unit ID cable contains black, brown, red, orange, and yellow wires. The
black wire plugs into the drive pin used to select ID0, the brown wire plugs into
the drive pin for ID1, the red wire plugs into the drive pin for ID2, and the orange
wire connects to ID3. Most drive manufacturers label these pins as ID0, ID1, ID2
and ID3, or similar identification. The yellow wire plugs into the drive activity
LED pin.

Drives use a row of pins to provide ground to the ID signals. This row of pins
is not used for the DE300i-SW installation. One end of the unit ID cable connects
to the signal row of ID pins on the drive. The other end of this cable attaches
to the ID select connector on the inside of the carrier (Figures 6 & 7). Refer to
the drive manufacturer's documentation for more information.

Installation 9

TYPICAL 2MM DRIVE ID PIN CONFIGURATION

Figure 7 illustrates a typical SCSI ID select connection to a drive with 2mm ID select pins. In
most cases, the drive manufacturer labels each pair of SCSI ID select pins in their significant
bit order (0, 1, 2, 3 as shown in Figure 7). In other cases, the manufacturer does not label
these pins in their significant bit order, but instead, assigns pin numbers only. In any case,
all odd numbered pins or all even numbered pins will be the signal row. The wires on the wire
harness connect to the positive pin (or signal pins) on the drive. Refer to the device
manufacturer's documentation for additional pin numbering and jumper option information.

Attach the ID select cable to the drive using the 2mm connectors. Align the ID0 pin with the
black wire. Attach the other end of the ID select cable to the ID select connector located on
the carrier board, inside the carrier. Refer to the manufacturers documentation to disable
termination on the drive.

5. Adjust the front of the receiving frame so the carrier slides freely in and out on the
receiving frame guides. The position of adjoining peripheral units may require
adjustment.

6. To connect a drive to a remote activity LED in the computer system or expansion chassis,
connect the appropriate cable(s) to the receiving frame motherboard connectors J3A,
J3B, and J3C Pins 11 & 12 as shown in Figure 5.

7. Connect the I/O cable from the host adapter to the receiving frame. The Pin 1 indicator
on the cable must be properly aligned. Refer to Figure 5 for the correct Pin 1 location.

8. When installing the DE300i-SW into a computer system, make sure that only the last SCSI
device is terminated. If the DE300i-SW is at the end of a daisy chain, the receiving frame
termination for the last device must be enabled by removing the appropriate
jumper. If the DE300i-SW is in the middle of a daisy chain, termination should be
disabled (factory installed jumper) at J3A, J3B, and J3C, Pins 9 & 10 (Figure 8).

In most cases, if installing the DE300i-SW into an external expansion chassis, the
factory-installed jumpers at J3A, J3B and J3C, Pins 9 & 10 (disable termination) should
be left in place. Termination will be handled by an external terminator on the expansion
chassis.

9. Connect the power cable from the DC power supply in the computer or expansion
chassis to the power connector on the DE300i-SW receiving frame. Refer to Figure
5 for the receiving frame power connector location.

10. Replace any expansion boards that may have been removed earlier. Replace the
system cover according to the manufacturers instructions.

11. Reconnect any system or peripheral cables removed earlier.

StorCase Technology, Inc. DE300i-SW User's Guide - Rev. A01

Installation 13

12. If the DE300i-SW has been installed into an external expansion chassis, connect the
SCSI and power cables to the chassis. If the expansion chassis is at the end of a
daisy chain, make certain that it is properly terminated. Refer to the computer system
and expansion chassis manuals for information on how to do this. Turn on the
expansion chassis power before turning on the computer system power.

13. Turn ON power to the computer. If the installation has been successful, and all cables
have been properly attached, the system should boot normally. Although the
computer may not recognize the DE300i-SW yet, the appropriate front panel LED
indicators on the Data Express should illuminate. If the system does not boot properly,
there could be a SCSI ID conflict. Refer to the following section "Selecting the Unit
ID Number".

NOTE: The lock on the DE300i-SW receiving frame functions as a lock and a DC

power switch for the carrier unit. The lock must be engaged (turned
counterclockwise) in order to supply power to the carrier and installed drive
unit.

14. The new drives may need to be formatted or initialized prior to use with the operating

system and applications software. Additionally, an appropriate driver may need to
installed for the host controller to recognize the newly installed device. Refer to the
drive and/or computer manufacturer's documentation for formatting information.
Refer to the host controller instructions for driver information.

SelectingtheUnitID Number

Each SCSI device on the computer system requires a separate SCSI ID number.

16-bit SCSI interface protocol permits 16 (0-15) unique SCSI ID numbers. Usually, ID7 is
reserved for the host controller. If the computer system has any internal or external SCSI
devices, some ID numbers may already be reserved. For instance, if the computer system
is already equipped with an internal SCSI hard drive, the drive may be designated as SCSI
device "0". Refer to the computer system documentation for additional information.

1. Verify that power is turned on to the DE300i-SW receiving frame by turning on the
computer or external expansion chassis. A number should appear in the unit ID display
window if the carrier is locked into place.

2. Unlock the DE300i-SW carrier from the receiving frame. The unit ID number will begin
flashing, indicating that the drive is spinning down. DO NOT REMOVE THE CARRIER
FROM THE RECEIVING FRAME WHILE THE UNIT ID NUMBER IS FLASHING. The length
of time that the unit ID number flashes is controlled by a small timing switch located on
the side of the receiving frame. Refer to Appendix B for information on adjusting the
timer (Figure B-3).

DE300i-SW User's Guide - Rev. A01 StorCase Technology, Inc.

14 Installation

WARNING: Unlocking the carrier unit switches DC power off to the drive. Since drives

require a short amount of time to spin down, allow at least 15 seconds before pulling
the carrier unit out of the receiving frame to avoid possible damage to the drive.

3. A "u" will be displayed once the drive has completed spin down and is ready to be
removed from the receiving frame. The indicator will return to the SCSI ID number when
the carrier is removed from the receiving frame.

4. Use the alignment tool supplied with the DE300i-SW to select the ID number of the disk
drive. Refer to Figure 10 for the location of the unit ID select switch inside the receiving
frame.

WARNING: Selecting an invalid ID number, or selecting the same unit ID number on different

5. After selecting an appropriate unit ID number, replace the DE300i-SW carrier in the
receiving frame, and LOCK IT IN PLACE.

6. If the DE300i-SW has been installed into an external expansion chassis, verify that
power is on to the chassis and that the last device in the SCSI daisy chain is properly
terminated.

7. Reboot the computer system.

Adjusting the Spin Down/Up Timer

NOTE: The timer for device spin down is controlled by a small selector, located in a cutout

on the side of the DE300 receiving frame as shown in Figure 11. The amount of
time required for a drive to spin down is approximately 15 seconds or more. This
number can vary depending on the type of SCSI device and manufacturer (some
drives may require 45 seconds or more). The factory configuration is set for 20
seconds. A different delay time may be selected with the provided alignment tool.
Refer to the SCSI device manufacturers manual for more information on required
device spin down time.

Appendix B - Factory-Installed Options

Hot Swap Board

The DE300i-SW/H SCSI Hot Swap Board allows the installation, removal or exchange of
DE300i-SW carriers while your computer system is operating by monitoring and protecting the
computer system and other peripheral devices on the SCSI Bus. The Hot Swap option
eliminates the need to shut down your system when adding or removing a SCSI device by
performing two functions:

1. Delays power up/down of the drive until the time period between SCSI bus cycles. This

prevents the interruption of any SCSI bus activity being done by other devices on the
bus.

2. Prevents drive power sequencing from generating noise on the SCSI bus, thus

preventing data transfer corruption on other devices.

Please note that, whereas UNIX and Apple-based systems provide mount/dismount drive
commands, most PC systems do not provide such a feature. When using one of these operating
systems, it may be necessary to reboot the computer after adding or changing a drive. This
reboot activity will force the SCSI host adapter to rescan its SCSI bus for physically attached
drives, and will then be able to access the new or changed drive.

Attaching the Hot Swap Board

If the Hot Swap Board is not already attached to the DE300 receiving frame, follow the steps
below for installation instructions. Otherwise, proceed to the "Using the Hot Swap Board"
section for usage instructions.

IMPORTANT NOTE: The device carriers should be locked into the receiving frame prior to the

StorCase Technology, Inc. DE300i-SW User's Guide - Rev. A01

following procedure to maintain proper connector alignment between the

Appendix B - Factory-Installed Options 21

Figure B-1: Attaching the Hot Swap Board

Jumper Options

Most jumper options are configurable via the receiving frame motherboard (Figures 5 & 8).
The Hot Swap Board provides three configurable jumpers, DTA, DTB, and DTC (Figure B-2).
When installed (factory default), these jumpers disable onboard termination at drives A, B, and
C, respectively. If a DE300 drive will be physically located at the end of a SCSI daisy chain,
remove the appropriate jumper to enable termination.

Using the Hot Swap Board

Carrier Removal

Follow the procedures below to remove the Data Express carrier from the receiving frame
equipped with the Hot Swap option.

1. Verify that the drive is not active. If the system is on a network, make certain other users
are not accessing the target drive, then disable it from the network. Dismount the drive.

2. Turn the DE300 key lock mechanism (located on the front of the receiving frame),
clockwise to the OFF position. This unlocks the drive from the receiving frame and
activates the Hot Swap Board. The unit ID number on the display will begin flashing.

WARNING: Be careful not to remove or disturb the carrier unit at this point. Although

DE300i-SW User's Guide - Rev. A01 StorCase Technology, Inc.

the carrier is physically unlocked, the drive requires a minimum of 15
seconds to spin down and is subject to vibration and possible damage
during this period.

3. As the unit ID number flashes, the Hot Swap Board monitors the activity of the SCSI
bus. When activity is no longer present, the Hot Swap Board will remove power from
the drive and then remove the device from the SCSI Bus. The unit number will continue
to flash during this period.

4. After a short length of time the unit ID display will turn from a flashing unit ID number
to a steady u, indicating that the device is powered down, unlocked and ready to be
removed from the receiving frame.

Carrier Installation

Follow the procedures below to install the DE300i-SW Carrier into the receiving frame equipped
with the Hot Swap option.

1. Install the Carrier into the Receiving Frame. A "u" will be present on the front panel.

2. Turn the key lock mechanism, located on the front of the receiving frame, counter
clockwise to the ON position. This locks the drive into the receiving frame and activates
the Hot Swap Board. The drive will begin to spin up and the unit number on the display
will begin flashing.

3. After a short length of time the unit display will stop flashing, indicating that the device
is ready to be used.

Appendix C - Attaching the ON/OFF Key

The following information will provide the necessary steps to attach the ON/OFF key to the
key lock mechanism so that it is non-removable, preventing accidental key loss. The procedure
can be reversed at a later date to revert back to a removable key.

1. Make certain power is OFF to the receiving frame.

Locate the rectangular shaped key lock mecha­nism access hole on the inside of the receiving
frame. Note that the pawl is in an upright position.

Insert the key into the key lock.

2. Rotate the key 90 degrees counterclockwise so
that the pawl is visible in the access hole as
shown in the figure at left.

3. Using the provided alignment tool, unscrew and
remove the pawl from the access hole.

4. Rotate the key 180 degrees clockwise.

5. Reinstall the pawl into the access hole with the
alignment tool.

Your key is now attached to the key lock mecha­nism.
