Chassis Intrusion Alarm Switch
The chassis intrusion alarm switch is mounted to the bottom panel of the base unit chassis near the
front card guide. See the System Board Manual for connector and socket locations.
To replace the chassis intrusion alarm switch:
WARNING The system is always on when connected to AC power. Before performing this
task, disconnect the system’s power cord from its AC power outlet.
1. Disconnect the alarm switch cable from its connector on the system board.
2. Remove and retain the screws that secure the switch to the base unit chassis, and remove the
switch and its cable from the chassis.
3. Align the new switch with the chassis mounting holes and secure it to the chassis with the
screws removed previously. Make sure the switch tab faces the back of the base unit.
4. Connect the alarm switch cable to its connector on the system board.
