Installation 13
12. If the DE300i-SW 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 information on how to do this. Turn on the
expansion chassis power before turning on the computer system power.
13. 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 DE300i-SW yet, the appropriate front panel LED
indicators on the Data Express 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 DE300i-SW 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.
14. 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 DE300i-SW 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 DE300i-SW 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 ID NUMBER IS FLASHING. 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 Appendix B for information on adjusting the
timer (Figure B-3).
