• The Key Lock/Drive Power Switch performs three (3) functions. The key lock
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 DE100 disk drive, the key must
be turned counterclockwise to the locked position.
The key may also be permanently attached (optional) to the locking mechanism as
shown in Appendix C.
• The Unit ID Number Indicator (Figure 4) displays the physical address of the
DE100 drive carrier when the carrier is Installed and Locked in the receiving frame
or Removed from the receiving frame. If the drive carrier is Installed but Not Locked,
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 DE100. This procedure is explained later during the
installation process.
• 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 DE100 carrier. This
dot will flash during communication with the host computer.
• Device Spin Down/Up Timer may be disabled by removing Jumper J6 P1-P2
(Figure 5). This feature allows the receiving frame unit number display to provide
a visual indication of drive spin down/up activity. Refer to Figure 11 for switch
settings.
