Modifying the Processor for Key Mode

To modify the processor for Key mode in Release 3.0 and later, 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.

! Remove the control unit housing. See Figure 9–1.

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

! Remove the processor module from the carrier. See Figure 9–3.

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