The Receiving Frame Front Panel
• The Key Lock/Drive Power Switch performs three functions. The key lock
assures proper seating of the device carrier within the receiving frame, it turns
power to the device carrier on and off, and it 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 counterclockwise to the locked position.
The key can optionally be attached to the locking mechanism as shown in
Appendix A.
• Front Panel Indicator LEDs (Figure 2)
Indicator LEDs on the DE90 receiving frame front panel provide important
operating information based on the following conditions:

possible drive damage.
