12 Installation
11. Turn on power to the computer. If the installation has been successful, and all cables
have been properly attached, the system should boot normally. Although the computer
may not recognize the DE75i-SW160 yet, the appropriate front panel LED indicators on
the front panel should illuminate. If the system does not boot properly, there could be
a SCSI ID conflict. Refer to the following section Selecting the Unit Number.
NOTE: The lock on the DE75i-SW160 receiving frame functions as a lock and
a DC power switch for the carrier unit. The lock must be engaged
(turned counterclockwise) in order to supply power to the carrier and
installed drive unit.
12. The new drive may need to be formatted or initialized prior to use with the operating
system and applications software. Additionally, an appropriate driver may need to
be installed for the host controller to recognize the newly installed device. Refer to
the drive and/or computer manufacturer's documentation for formatting information.
Refer to the host controller instructions for driver information.
Selecting the Unit ID Number
Each SCSI device on the computer system requires a separate SCSI ID number.
16-bit SCSI interface protocol permits 16 (0-15) unique SCSI ID numbers. Usually, ID7 is
reserved for the host controller. If the computer system has any internal or external SCSI
devices, some ID numbers may already be reserved. For instance, if the computer
system is already equipped with an internal SCSI hard drive, the drive may be designated
as SCSI device "0". Refer to the computer system documentation for additional informa-
tion.
1. Verify that power is turned on to the DE75i-SW160 receiving frame by turning on
the computer or external expansion chassis. A number should appear in the unit
display window if the carrier is locked into place.
2. Unlock the DE75i-SW160 carrier from the receiving frame. The unit ID number will
begin flashing, indicating that the drive is spinning down. DO NOT REMOVE THE
CARRIER FROM THE RECEIVING FRAME WHILE THE UNIT NUMBER IS FLASHING.
The length of time that the unit number flashes is controlled by a small timing
switch located on the side of the receiving frame. Refer to Figure 11 for
information on adjusting the timer.
WARNING: Unlocking the carrier unit switches DC power off to the drive. Since
drives require a short amount of time to spin down, allow at least 15
seconds before pulling the carrier unit out of the receiving frame to
avoid possible damage to the drive.
