Reinitiate the forced installation by power-cycling the system after inserting the memory card.

Replacing the Processor Module

A failed processor module must be replaced immediately. To replace the processor module, follow
these steps:
1. Backup system programming to a floppy disk or memory card.
See "Backup" in Programming Basics to backup to floppy disk, or Appendix D, "Backing up
with a Memory Card" to backup to a memory card.
2. Power down the system.
a. Turn off the power supply on the basic carrier.
b. Turn off the power supply on each expansion carrier.
c. Unplug the auxiliary power units (if present) from the AC outlet.
3. Unplug the D8W cord(s) connecting the SMDR printer and/or system programming PC.
4. Remove the processor module.
5. Inspect the processor module for any visible problems.
6. Inspect the carrier.
7. Install the new processor module.
8. Power up the system.
a. Turn on the power supply on each expansion carrier.
b. Turn on the power supply on the basic carrier. The system automatically cold starts.
9. Perform a System Erase (frigid start). See
10. Restore system programming using one of the following:
The backup floppy disk or original system programming disk. See "Using Standard SPM"
I
in Programming Basics for instructions to restore system programming.
The backup memory card or original system programming memory card. See Restore in
I
Appendix D, "Backing Up with a Memory Card," for instructions.
11. Reconnect the D8W cord(s) connecting the SMDR printer and/or system programming PC.
