StorCase Technology DE100i-CSWTN User Manual

Wide to Narrow DE100 Carrier

The DE100i-CSWTN is a Data Express® DE100 carrier designed to accommodate Wide
68-pin HD devices but interfaces to a Narrow 50-pin MM (HD50) DE100 receiving frame,

specifically, the DE100-S receiving frame.

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

Installation

1. Attach the I/O cable from the rear distribution board of the Data Express
carrier to the disk drive (Figure 1).

2. Attach the 4-pin DC power cable from the rear distribution board to the disk
drive (Figure 1).

3. Install the 5-pin ID select cable into the rear signal distribution board
connector. Refer to Figure 2 for a typical 2mm drive pin connection.

4. Carefully insert the drive into the carrier at an angle, cable-end first. Make
sure none of the cables are pinched. Lower the front of the drive
carefully into place. Fasten the drive into the carrier with four (4) #6-32 x 3/
16" Flat Head screws provided (Figure 1).

5. Attach the provided cable cover with two (2) #6-32 x 3/16" F.H. screws.

Typical 2mm Drive ID Pin Configuration

Figure 2 illustrates a typical SCSI ID select connection to a drive with 2mm ID select pins.
The wires on the wire harness connect to the positive pins (or signal pins) on the disk
drive. In some cases, the drive manufacturer will label the signal pins as Pin 1, 3, 5, and 7
(instead of 0, 1, 2, and 3 as shown in Figure 2 below). Also, in some cases, the even­numbered Pins 2, 4, and 6, are used for Ground.

Attach the ID select cable to the drive using the 2mm connectors. Align the "ID0" pin with
the black wire. Attach the 1.25mm connector on the other end of the ID select cable to
the 1.25mm connector (J3B) provided on the signal distribution board, located inside the
carrier. Refer to the manufacturer's documentation to disable termination on the drive.

NOTE: The cables are made up of black, brown, red, orange, and yellow wires.

The black wire is plugged into the ID0 pin, the brown wire into the ID1 pin, the
red wire into the ID2 pin, and the yellow wire into the Drive Activity LED pin.
The orange wire is not used.
