Eagle 100-500 Rear Panel Screws

Refer to the following steps and illustration to unfasten the main electronics board from the standard
Eagle rear panel.

1.  Remove the five Phillips-head screws on the chassis rear panel where indicated in the

illustration. These five screws hold the rear panel adapter plate to the chassis. After removing
these screws, you can remove the main electronics board assembly without having to remove all
the serial I/O connectors from the rear panel.

2.  Next, unplug the external SCSI termination plug and remove the two Phillips-head screws that

secure the SCSI connector to the rear panel. Then, push the SCSI connector back into the chassis
so it is no longer protruding through the rear panel.

3.  On Eagle 100 systems, disconnect the 50-pin SCSI cable from the connector on the main

electronics board (the AM-137 CPU board).
