12 Installation
9. Replace any expansion boards that may have been removed earlier. Replace the
system cover according to the manufacturer’s instructions.
10. Reconnect any system or peripheral cables removed earlier.
11. If the DE300 has been installed into an external expansion chassis, connect the SCSI
and power cables to the chassis. If the expansion chassis is at the end of a daisy
chain, make certain that it is properly terminated. Refer to the computer system and
expansion chassis manuals for further information. Turn ON the expansion chassis
power before turning on the computer system power.
12. 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 DE300 yet, the appropriate front panel LED indicators
on the DE300 should illuminate. If the system does not boot properly, there could be
a SCSI ID conflict. Refer to the following section "Selecting the Unit ID Number".
NOTE: The lock on the DE300 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.
13. The new drives may need to be formatted or initialized prior to use with the operating
system and applications software. Additionally, an appropriate driver may need to
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 information.
1. Verify that power is turned on to the DE300 receiving frame by turning on the computer
or external expansion chassis. A number should appear in the unit ID display window
if the carrier is locked into place.
2. Unlock the DE300 carrier from the receiving frame. The unit ID number will begin
flashing, indicating that the drive is spinning down. The length of time that the unit ID
number flashes is controlled by a small timing switch located on the side of the receiving
frame. Refer to Figure 10 for the location of the Device Spin Down/Up Timer on the
receiving frame. A "u" will be displayed once the drive has completed spin down and
is ready to be removed from the receiving frame. The indicator will return to the SCSI
ID number when the carrier is removed from the receiving frame.
