2. Unlock the Data Express carrier from the receiving frame. The unit 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 Appendix B for information on adjusting the
timer (Figure B-3).
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.
3. 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.
4. Use the alignment tool supplied with the Data Express to select the unit number of the
disk drive. Refer to Figure 13 for the location of the unit ID select switch inside the
receiving frame.
5. After selecting an appropriate unit ID number, replace the Data Express carrier in the
receiving frame, and LOCK IT IN PLACE.
6. If the Data Express has been installed into an external expansion chassis, verify that
power is on to the chassis and that the last device in a SCSI daisy chain is properly
terminated.
7. Reboot the computer system.
WARNING: Selecting an invalid ID number, or selecting the same unit ID number on
different devices may cause unpredictable results and the computer system
may not recognize the installed device(s). If the computer system can not
recognize the boot disk, the computer system may fail to start-up properly.
