• 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 DE75i-A66
drive, the key must be turned counterclockwise to the locked position.
• The Unit Number Indicator displays the physical address of the DE75i-A66
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. The unit number is selected by means of the
unit select switch located inside the receiving frame using a special alignment
tool supplied with the DE75i-A66. 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 DE75i-A66
carrier.
