Introduction 3

GeneralDescription

The StorCase Technology Data Express® DE75 (P/N S20A114) is composed of a receiving
frame which supports most 68-pin SCSI Ultra160 (LVD) interfaces and fits within a 5.25" half­height peripheral slot. This 16-bit I/O can support up to 160MByte/sec transfer rates. The
receiving frame contains one (1) removable drive carrier designed to provide durable and
reliable mounting for one (1) 3.5" form factor, low-profile (up to 1" high), SCSI Wide, Wide Ultra,
Wide Ultra2 or Wide Ultra160 drive (Figure 2).

The S20A114 allows a drive to be removed and transported to another S20A114-equipped
computer or expansion chassis, and also provides the ability to secure sensitive data by
removing and storing the drive safely for future use.

NOTES: The S20A114 carrier supports most 68-pin SCSI Ultra160 interfaces, except Fujitsu

Alegro6 10K RPM drives (these drives have different spacing between the 68-pin

and DC power connectors and will not mate with the drive carrier board).

For SCSI Ultra160 operation, the DE75 requires Ultra160 chassis and cabling.

(Figure 3)

 Key Lock/Drive Power Switch (Figure 3) - Performs three functions. The key

switch 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 disk drive, the key
must be turned counterclockwise to the locked position. The key can be configured
as either fixed or removable as shown in Appendix B.

 Unit ID Number Indicator (Figures 3 & 4) - This LED displays the physical address

of the DE75 device carrier if the carrier is Installed and Locked in the receiving frame

or if the carrier is removed from the receiving frame. If the carrier is Installed but
not Locked in the receiving frame, 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 DE75 (see Figure

9).

 The Activity Indicator (Figures 3 & 4) - A small dot next to the unit ID number

illuminates to indicate when the host computer is accessing the data on the DE75
carrier. This dot will flash during communication with the host computer.

 Device Spin Down/Up Timer Switch (Figure 3) - This switch controls the length

of time that the activity indicator flashes during device spin down/up, providing a
visual indication of drive activity. Refer to Figure 10 for switch settings.

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

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.

Appendix B - 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, if so desired.

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.

The key is now attached to the key lock mecha­nism.
