• 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 DE150i-SWC 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
DE150i-SWC 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 DE150i-SWC. 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 DE150i-SWC 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 10 for switch
settings.
