Monitoring Power Module Performance
The computer inside the Power Module is continually monitoring Power Module performance.

appears on the front of the Power Module. The yellow wrench is accompanied by an audio tone.
This is a steady or beeping tone, depending on the condition. Refer to
Handling Power Module
Alarms on page 7-29 for guidelines on handling Power Module alarms.
