The Receiving Frame Front Panel
• The Key Lock/Drive Power Switch performs three 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 Data Express
disk drive, the key must be turned counter-clockwise to the locked position.
The key may also be permanently attached to the locking mechanism as shown in
Appendix C.
• The Unit Number Indicator (Figure 4) displays the physical address of the Data
Express 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
number is selected by means of the unit select switch inside the receiving frame
using a special alignment tool supplied with the Data Express. This procedure is
explained later during the installation process.
• The Activity Indicator is a small dot next to the Unit Number which illuminates to
show when the host computer is accessing the data on the Data Express carrier.
This dot will flash during communication with the host computer.
• Device Spin Up/Down Timer allows the receiving frame unit number display to
provide a visual indication of drive spin up/down activity. Refer to Figure B-4 for
switch settings.
