• The Key Lock/Drive Power Switch performs three (3) functions. The key lock
assures proper seating of the device carrier within the receiving frame, turns power
to the device carrier on and off, and prevents unauthorized removal or installation
of the carrier. For the computer to access data on the DE75i-SWC160 disk drive,
the key must be turned counterclockwise to the locked position.
The key can be attached (optional) to the locking mechanism as shown in
Appendix B.
• The Unit ID Number Indicator (also refer to Figure 4) displays the physical SCSI
address of the DE75i-SWC160 device carrier if the carrier is Installed and Locked
in the receiving frame or if the carrier is Removed from the receiving frame. If the
carrier is Installed but Not Locked in the receiving frame, a "u" will be displayed to
indicate an unlocked condition. The unit ID number is selected by means of the unit
ID select switch inside the receiving frame using a special alignment tool supplied
with the DE75i-SWC160.
• The Activity Indicator is a small dot next to the Unit ID Number which illuminates
to show when the host computer is accessing the data on the DE75i-SWC160
carrier. This dot will flash during communication with the host computer.
