• 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-SWC 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 C.
• The Unit Number Indicator (also refer to Figure 4) displays the physical
address of the DE75i-SWC 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 number is selected by means of the
unit select switch inside the receiving frame using a special alignment tool
supplied with the DE75i-SWC.
• The Activity Indicator is a small dot next to the Unit Number which illuminates
to show when the host computer is accessing the data on the DE75i-SWC
carrier. This dot will flash during communication with the host computer.
