Modifying the Processor for Key Mode

Modifying the Processor

for Key Mode

To modify the processor for Key mode in Release 3.0, follow the steps below. For earlier releases, see Appendix E in Maintenance and Troubleshooting.

Prepare a non-metallic surface, such as a table, on which to work.

WARNING:

Do not touch the gold connectors on the rear of the processor module. Electrostatic discharge (ESD) can damage the circuitry, as can the oil from your fingertips. Use a properly grounded wrist strap to prevent damage from electrostatic discharge.

Only a qualified technician should perform this procedure.

1Remove the control unit housing. See Figure 9-1.

2Power down the system as described earlier in this chapter. See Figure 9-2.

3Remove the processor module from the carrier. See Figure 9-3.

4Place the processor module on a flat surface with the wiring manager on your left.
