• 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 DE300i-SWC160 disk drive,
the key must be turned counterclockwise to the locked position.
The key may also be permanently attached to the locking mechanism as shown in
Appendix B.
• The Unit ID Number Indicator (Figure 4) displays the physical SCSI address of
the DE300i-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 number is selected by means of the unit ID select
switch inside the receiving frame using a special alignment tool supplied with the
DE300i-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 DE300i-SWC160
carrier. This dot will flash during communication with the host computer.
• Device Spin Down/Up Timer - This feature allows the receiving frame unit ID
number display to provide a visual indication of drive spin down/up activity. A small
timing switch located on the side of the receiving frame allows the operator to adjust
the timer to match the specific drive manufacturer's specifications (Figure 10).
