Receiving Frame Front Panel
(Refer to Figure 3)
The Key Lock/Drive Power Switch
performs three (3) 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
DE300i-SWC disk drive, the key must be turned counterclockwise to the locked
position.
The key can be attached (optional) to the locking mechanism as shown in
Appendix C.
The Unit Number Indicator
(Figure 4) displays the physical address of the
DE300i-SWC 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 DE300i-SWC.
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
DE300i-SWC carrier. This dot will flash during communication with the host
computer.
Device Spin Down/Up Timer
This feature allows the receiving frame unit
number display to provide a visual indication of drive spin down/up activity. A
small timing switch located on the side of the receiving frame allows the
operator to adjust the timer to match the specific drive manufacturer's specifica-
tions (Figure B-3).
