(Figure 3)
• The Key Lock/Drive Power Switch performs three 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 drive, the key must be turned
counterclockwise to the locked position.
The key is permanently attached to the lock but can be reconfigured to be removable,
if desired (as shown in Appendix C).
• The Unit ID Number Indicator (Figure 4) displays the physical address of the Data
Express 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 select switch inside
the receiving frame using a special alignment tool supplied with the DE200i-SWCU2.
• 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 DE200i-SWCU2
carrier. This dot will flash during communication with the host computer.
• Device Spin Down/Up Timer allows the receiving frame unit number display to
provide a visual indication of drive spin down/up activity. Refer to Figure 10 for
switch settings.
