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-
S 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:
This cable carries the SCSI ID signal between the drive and the
carrier. The signal is 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 DE75i-
S carrier is supplied with two (2) 3-wire cables. One cable contains 0.1" and
2mm connectors, the other cable uses 0.1" and 1.25mm connectors. One end
of the SCSI ID cable attaches to the carrier signal distribution board (inside the
carrier), the other end of the cable attaches to the ID pins on the drive (Figure
7). Use the appropriate ID cable for your specific drive.
The unit ID cable contains
black
,
brown
,
and
,
red
wires. The
black
wire plugs
into the drive pin used to select ID0, the
brown
wire plugs into the drive pin for
ID1, and the
red
wire plugs into the drive pin for ID2. Most drive manufacturers
label these pins as ID0, ID1 and ID2, or similar identification. LED activity is handled
through the Data Express logic (Figure 5).
Drives use a row of pins to provide ground to the ID signals. This row of pins
is not used for the Data Express 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.
