(Figure 3)

•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 DE100i-A100 drive, the key must be turned counterclockwise to the locked position.

•Unit ID Number Display (Figure 4) shows the physical address of the DE100i-A100 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 ID number is selected by means of the unit ID select switch located inside the receiving frame using a special alignment tool supplied with the DE100i-A100. This procedure is explained later during the installation process.

•Activity Indicator is a small dot next to the Unit ID Number which flashes when the host computer is accessing data on the DE100i-A100 carrier. Refer to Figure 6 on page 7 and section "Drive Activity Indicator Connector (J5)" on page 8 for further information.

•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.
