• 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 DE200i-SWU2
disk drive, the key must be turned counterclockwise to the locked position.
The key is permanently attached to the lock but can be reconfigured to be
removable, if desired (as shown in Appendix C).
• The Unit Number Indicator (Figure 4) displays the physical address of the
DE200i-SWU2 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 DE200i-
SWU2. 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 DE200i-SWU2
carrier. This dot will flash during communication with the host computer.
• Device Spin Down/Up Timer allows the receiving frame unit number display
to provide a visual indication of drive spin down/up activity. Refer to Figure B-4
for switch settings.
