4 Introduction

ReceivingFrameFrontPanel

(Figure 3)

 The Key Lock/Drive Power Switch performs three 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 DE75i-A100 drive, the key must
be turned counterclockwise to the locked position.

 The Unit ID Number Indicator displays the physical address of the DE75i-A100

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. The unit ID number is selected by means of the unit ID select
switch located inside the receiving frame using a special alignment tool supplied with
the DE75i-A100. 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 DE75i-A100 carrier.

INSTALLATION

InstallingtheDriveintotheCarrier

Preparation

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

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.

1. Remove the drive from its protective packaging.

2. Plastic Drive Bezel: If the drive came equipped with a plastic front panel (bezel),

it must be removed before installing the drive into the drive carrier.

3. Master/Slave Drive Selection: There are two (2) ways to set the Master/Slave

drive designation for the DE75i-A100 unit. Refer to Method 1 and/or Method 2 in the
following sections for further information.

Master/Slave Drive Selection

Method 1 (Recommended) - Using the factory-installed jumper on your IDE drive

In most cases, the drive will be factory-configured as a Master Ultra ATA133 drive using a
jumper plug on the drive itself. No configuration changes are required. For multiple drive
configurations, it is necessary to set the first IDE drive as Master and the second IDE drive
to Slave. This can be done by changing the jumper on the Ultra ATA133 drive itself (refer to
your drive manufacturer documentation).

This method requires no additional configuration of the drive carrier circuit board.

However, the appropriate jumper setting must still be configured on JP6 (ID0 & ID1) located
on the receiving frame motherboard (Figure 4). For Master setting, install jumper on ID0 (Pins
1 & 2). For slave setting, install jumper on ID1 (Pins 3 & 4).

Skip the Method 2 section and continue with section "Installing the Receiving Frame".

StorCase Technology, Inc. DE75i-A100 User's Guide - Rev. D02

Installation 7

Method 2 - Using the hard-wire connector JP3 on the drive carrier circuit board to allow

drive carrier interchangeability between Master/Slave configured receiving
frames

NOTE: Cable wire not included.

For drive carrier interchangeability between Master/Slave configured receiving frames,it is
necessary to set the Master/Slave drive selection by both a hard-wire connection (cable wires
not included) between the drive and the drive carrier circuit board.

This method requires the fabrication of a cable wire (not provided). Refer to the following
sections to configure the drive carrier circuit board and jumper (JP4) located on the receiving
frame (both required for Method 2).

Configuring the Drive Carrier Circuit Board

The appropriate pins on the drive must be connected to JP3 on the carrier board. These
connections are required to set the Master/Slave configurations of the installed drive. Figure
5 illustrates the Drive Carrier Circuit Board.

When configuring the dual drives for interchangeable Master/Slave assignment, it is necessary
to emulate the Master and Slave drive jumpers and the specific drive's signal polarity definition
of Master and Slave.

Examples of Ultra ATA133 drive pin positions are shown in Figure 6. Remove and save all
jumpers. Install a cable wire (not provided) connecting the appropriate drive pins to the
appropriate JP3 pins as shown in Figure 6. Installation of a jumper may also be necessary,
depending on model.

NOTE: Pin assignments may vary depending on model, refer to the drive manu-

facturer's documentation for specific information regarding your drive.

Configuring the Receiving Frame Motherboard (JP4)

Once the Master/Slave configuration on the drive carrier circuit board is complete, the JP4
jumper(s) on the receiving frame motherboard must be configured as shown in Figure 7.

The appropriate jumper setting must still be configured on JP6 (ID0 & ID1) located on the
receiving frame motherboard (Figure 4). For Master setting, install jumper on ID0 (Pins 1 & 2).
For slave setting, install jumper on ID1 (Pins 3 & 4).
