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. SCSI Drive Termination: Disable or remove the termination resistor packs
from the drive. Termination is performed by an external terminator in the
DE75i-SW receiving frame (Figure 5). 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 drive, and remove any jumper plugs in this area. The SCSI ID cable will be
installed into this section of the drive (Figure 6).
5. SCSI ID Cable: The DE75i-SW carrier is supplied with one (1) 5-wire cable. This
cable carries the SCSI ID signal between the drive and the carrier. The signal
is then transferred to/from the receiving frame via the carrier and receiving frame
mating connectors. The ID cable permits unit ID selection via a small switch
located on the inside of the receiving frame (Figure 10). The cable is designed
to connect to drives with 2mm ID select connectors. Attach the five (5)
connectors from the carrier SCSI unit ID cable to the appropriate drive pins (Figure
7).
The unit ID cable contains black, brown, red, orange, and yellow wires. The
black wire plugs into the drive pin used to select ID0, the brown wire plugs into
the drive pin for ID1, the red wire plugs into the drive pin for ID2, and the orange
wire connects to ID3. Most drive manufacturers label these pins as ID0, ID1, ID2,
and ID3, or similar identification. The yellow wire plugs into the drive activity
LED pin.
Drives use a row of pins to provide ground to the ID signals. This row of pins
is not used for the DE75i-SW installation. One end of the unit ID cable connects
to the signal row of ID pins on the drive. The other end of this cable attaches
to the ID select connector on the inside of the carrier (Figures 6 & 7). Refer to
the drive manufacturer's documentation for more information.
