Power Supplies, Fans and Temperature Gauge
The iMediaChassis/20 supports modular fans and power supplies, so that worn parts
can be replaced without having to send an entire unit in for repair. Keeping fans
functional ensures that the modules will operate within their temperature
specifications.
Buzzer Reset Button
When one power supply malfunctions, an audible alarm sounds to indicate the loss
of one power supply. A Reset Buzzer button, located next to the power connector
on the power supply, stops this alarm. Remove and replace the power supply
immediately.
Last Gasp Alarm
The iMediaChassis/20 includes a Last Gasp feature, which sends a trap (configured in
iView²) when both power supplies malfunction, when both power supplies are
powered down, or when the AC line fails.
