• Key Lock/Drive Power Switch (Figure 3) - Performs three functions. The 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-SW160 drive,
the key must be turned counterclockwise 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 and 4) - This LED displays the physical
address of the DE75i-SW160 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-SW160 (see Figure 10).
• The Activity Indicator (Figures 3 and 4) - A small dot next to the unit ID number
illuminates to indicate when the host computer is accessing the data on the DE75i-
SW160 carrier. This dot will flash during communication with the host computer.
• Device Spin Down/Up Timer Switch (Figure 3) - This switch 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.
