The Receiving Frame Front Panel

• The Key Lock/Drive Power Switch performs three functions. The key lock
assures proper seating of the device carrier within the receiving frame, it turns
power to the device carrier on and off, and it prevents unauthorized removal or
installation of the carrier. For the computer to access data on the Data Express
disk drive, the key must be turned counterclockwise to the locked position.

The key can optionally be attached to the locking mechanism as shown in
Appendix A.

• Front Panel Indicator LEDs (Figure 2)
Indicator LEDs on the DE90 receiving frame front panel provide important
operating information based on the following conditions:

DATA EXPRESS INSTALLATION
Installing the Drive in 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 came equipped with a plastic front bezel, it
must be removed.

3. SCSI Drive Termination: Disable or remove the termination resistor packs
from the drive. Termination is handled by an external terminator in the Data
Express receiving frame. 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 disk drive, and remove any jumper plugs in this area. The
SCSI ID cable will be installed into this section of the drive.

5. SCSI ID Cable: The Data Express carrier is supplied with one (1), three­wire cable. This cable is used for remote ID selection via jumpers located on
the rear of the DE90 receiving frame. One end of this cable has a single
connector with 1.25mm pin spacing. The other end contains three separate
2mm connectors. This cable can be used with drives that have either 2mm
or 1.25mm pin configurations by simply reversing the cable. The Data
Express signal distribution board contains connectors that except either end
of this cable.

The cables are made up of black, brown, and red wires. The black wire is
plugged into the pin used to select ID0, the brown wire plugs into the pin for
ID1, and the red wire plugs into the pin for ID2. Most drive manufacturers
mark these pins with some sort of identification which corresponds to ID0,
ID1, and ID2.

Disk drives use a row of pins to provide ground to the ID signals. This row of
pins is not used when installing the ID select cable to the carrier connector.
Refer to your drive manufacturer's documentation for more information.
