• Key Lock and Power Switch (Figure 3) - This key switch assures proper seating
of the drive carrier within the receiving frame, turns power to the drive carrier on
and off, and prevents unauthorized removal or installation of the carrier. For the
computer to access data on the DE75i-S drive, the key must be turned counterclock-
wise to the locked position. The key can be configured as either fixed or removable
as shown in Appendix B.
• Unit ID Number Indicator (Figures 3 & 4) - This LED displays the physical address
of the DE75i-S 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-S (see
Figure 10).
• The Activity Indicator (Figures 3 & 4) - A small dot next to the unit ID number
illuminates to indicate when the host computer is accessing the data on the
DE75i-S carrier. This dot will flash during communication with the host computer.
• Device Spin Down/Up Timer (Figure 3) - This timer controls the length of time that
the unit number display flashes during device spin down/up, providing a visual
indication of drive activity. Refer to Figure 11 for switch settings.
