Introduction 1 INTRODUCTION Packaging Information The StorCase Technology Data Express® system is shipped in a container designed to provide protection and prevent damage during shipment. The Data Express unit was carefully inspected before and during the packing procedure at the factory. Bent or broken connectors, or evidence of other damage to the Data Express should be reported to the shipper immediately. Refer to Figure 1 for the package contents.

Introduction 3 General Description The StorCase Technology Data Express® DE75i-S is a removable drive carrier and receiving frame designed to provide durable and reliable mounting for 3.5 form factor, low-profile (up to 1" high), SCSI drives (Figure 2). The DE75i-S allows a drive to be removed and transported to another DE75i-S-equipped computer or expansion chassis, and also provides the ability to secure sensitive data by removing and storing the drive safely for future use.
4 Introduction Receiving Frame Front Panel (Figure 3) Key Lock and Power Switch (Figure 3) - This 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 DE75i-S 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.

6 Introduction Receiving Frame Rear Panel (Figure 5) I/O Connector - These connectors provide a standard interface for all SCSI signals (Figure 5). See Table 2 for pin assignments. DC Power Connector (J1) - A standard 4-pin DC power connector is used to accept DC power. Option Pins Remote Unit ID Selection - Pins 1-6 of this connector provide unit SCSI ID selection for the computer system or expansion chassis.
Installation 7 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.
8 Installation Installation 1. Attach the I/O cable from the carrier board to the drive (Figure 6). 2. Attach the 4-pin power cable from the carrier board to the drive (Figure 6). 3. Attach the appropriate ID select cable to the carrier board connector (Figure 7). 4. Carefully insert the drive into the carrier at an angle, cable-end first. Make sure that none of the cables are pinched. Lower the front of the drive carefully into place.
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 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.
10 Installation Installing the Receiving Frame The drive should be installed into the carrier before installing the receiving frame into the mounting bay of a computer or expansion chassis. NOTE: Use a #2 Phillips screwdriver during this procedure. 1. Turn OFF power to the computer. 2. Open the computer system according to the manufacturers instructions. If necessary, temporarily remove any expansion boards that may make installation difficult. 3.

12 Installation 4. With the drive carrier locked into place inside the receiving frame, install the DE75i-S receiving frame into the drive opening in the computer or expansion chassis. Use the appropriate guides to position the DE75i-S, and fasten it into place with four (4) #6-32 x 1/4 screws provided. Figure 9 illustrates the location of the mounting holes. Mounting holes are provided on each side and the bottom of the receiving frame to accommodate a variety of mounting configurations.
Installation 13 10. Replace any expansion boards that may have been removed earlier. Replace the system cover according to the manufacturers instructions. 11. Reconnect any system or peripheral cables removed earlier. 12. If the DE75i-S 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.
14 Installation 2. Unlock the DE75i-S carrier from the receiving frame. The unit 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 Figure 11 for adjusting the spin down/up timer. WARNING: Unlocking the carrier unit switches DC power off to the drive.
Installation 15 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 DE75i-S 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.
16 Installation SCSI Interface Connector The SCSI interface connector pin assignments are supplied for your convenience.

20 Appendix B - Attaching the ON/OFF Key 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. 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.
