4 Introduction

ReceivingFrameFrontPanel

 The Key Lock/Drive Power Switch performs three (3) functions. The key lock

assures proper seating of the drive carrier within the receiving frame, turns power
to the drive carrier on and off, and prevents unauthorized removal or installation of
the carrier. For the computer to access data on the DE150i-SWC disk drive, the key
must be turned counterclockwise to the locked position.

The key may also be permanently attached (optional) to the locking mechanism as
shown in Appendix C.

 The Unit ID Number Indicator (Figure 4) displays the physical address of the

DE150i-SWC drive carrier when the carrier is Installed and Locked in the receiving
frame or Removed from the receiving frame. If the drive carrier is Installed but Not
Locked, a "u" will be displayed to indicate an unlocked condition. The unit ID number
is selected by means of the unit ID select switch inside the receiving frame using
a special alignment tool supplied with the DE150i-SWC. This procedure is explained
later during the installation process.

 The Activity Indicator is a small dot next to the Unit ID Number which illuminates

to show when the host computer is accessing the data on the DE150i-SWC carrier.
This dot will flash during communication with the host computer.

Adjusting the Spin Down/Up Timer

The timer for device spin down is controlled by a small selector, located in a cutout on the side
of the DE150i-SWC receiving frame as shown in Figure 10. When the key is turned to the OFF
position, and when the timer receives a No SCSI Activity signal from the Isola-tor Board, it waits
the specified delay time before displaying a u on the front panel of the receiving frame. The
amount of time required for a disk drive to spin down is approxi-mately 15 seconds or more.
This number can vary depending on the type of SCSI device and manufacturer (e.g. a Seagate
Barracuda may require 45 seconds). 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.

DE150 Isolator Board

The Isolator Board is an upgrade attachment for the DE150i-SWC receiving frame. This
attachment provides a bus-isolating feature as described below.

Bus-Isolating Hot Swap Function

The DE150 SCSI Isolator Board (P/N DX100-SW/H) provides an enhanced, bus-isolating hot
swap function by allowing the installation, removal or exchange of DE150i-SWC carriers while
your computer system is operating by monitoring and protecting the computer system and other
peripheral devices on the SCSI Bus. The Isolator Board 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 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 re-scan its SCSI bus for physically attached
drives, and will then be able to access the new or changed drive.

Attaching the Isolator Board

The DE150i-SWC may be purchased with the Isolator Board factory-installed. If the Isolator
Board has not already been attached to the receiving frame, follow the instructions below to
add the board:

NOTE: The drive carrier must be installed in the receiving frame when removing or

StorCase Technology, Inc. DE150i-SWC User's Guide - Rev. B00

attaching the Isolator Board to ensure proper alignment between the motherboard
and the drive.

1. Remove the two (2) Phillips head machine screws from the receiving frame motherboard
and set the screws aside (Figure B-1).

2. Remove jumpers on the receiving frame motherboard locations J4 - Pins 7 & 8, and
J6 - Pins 1 & 2 (Figure 7). Also make sure that W2 is set to Position "A" (default setting)
to disable onboard termination from the receiving frame motherboard.

3. Attach the two (2) provided stand-offs into the receiving frame motherboard holes in
place of the two removed screws. Carefully align the connectors of the Isolator Board
with the connectors on the receiving frame board and gently push the board into
position. Make certain that all connectors are properly mated.

4. Attach the Isolator Board to the receiving frame motherboard by using the two screws
removed earlier and insert them through the board into the stand-offs.

Figure B-1: Attaching the Isolator Board

DE150i-SWC User's Guide - Rev. B00 StorCase Technology, Inc.

20 Appendix B - Factory-Installed Options

Carrier Removal

Follow the procedures below to remove the DE150i-SWC carrier from the receiving frame
equipped with the Isolator Board.

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 DE150 key lock mechanism (located on the front of the receiving frame),

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

Solenoid Drive Lock

The factory-installed solenoid option prevents premature removal of the carrier and drive unit
until the target drive has fully spun down. For most disk drives, this period of time can range
from 15-40 seconds, depending on the type of drive being used (e.g. Seagate Barracuda drives
require up to 50 seconds). Refer to the drive manufacturer's documentation for specific drive
information.

The solenoid lock is controlled by a timing switch located on the side of the receiving frame.
Refer to the section "Adjusting the Spin Down/Up Timer", for information describing the re­adjustment of the timer setting.

The solenoid option provides an extra step in drive protection by preventing the removal and
movement of the drive until the drive motor has fully stopped.

Appendix C - Attaching the ON/OFF Key

The following information describes 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 (or coun­terclockwise).

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

Your key is now attached to the key lock mecha­nism.
