Removal and Replacement 7-57
Removal
1. Shut down the operating system and power down the system.
2. Expose the system drawer.
3. Remove the four Phillips head screws holding the OCP tray to the system
drawer.
4. Slide the tray out of the system drawer far enough to disconnect cables attached
to the OCP, the floppy, and the CD-ROM drive.
5. Remove the tray from the system.
6. Move the tray to some handy work surface. Hold the tray vertically and remove
the two Phillips head screws that hold the OCP in place from the bottom of the
tray and remove the OCP assembly from the tray.
Replacement
Reverse the steps in the Removal procedure. As you replace the tray in the drawer,
be sure that the slides on the sides of the tray are placed on the rails in the drawer.
Verification
Power up the system. If the OCP you installed is faulty, the system will not power
up or you will not see messages on the OCP display.
