Removal and Replacement 7-59
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 and disconnect cables attached to the
OCP (unnecessary on a pedestal system), the floppy, and the CD-ROM drive.
(In the pedestal system the OCP is in the tray above the power supplies.)
5. Move the tray to some handy work surface. Hold the tray vertically and from
the bottom of the tray remove the four Phillips head screws that hold the floppy
in place and remove it 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. Use the following SRM console commands to test the floppy:
P00>>> show dev floppy
P00>>> HD buf/dva0
