Fault Monitor Module
The Fault Monitor Module is contained in the embedded microcontroller subsystem. The Fault
Monitor Module is designed to monitor and report on critical system events.
Alternatively, the Fault Monitor Module error-trace log can be retrieved and viewed using the
General Settings applet (Fault Monitor tab) of the Wave Global Administrator.
The Fault Monitor Module is in regular contact with the following Wave Server components:
• Microsoft Windows Server 2003 operating system
• Shutdown button
• Fans/power supply status bits
Microsoft Windows Server 2003 operating system
The FMM communicates with the operating system through a proprietary, low-level driver at
intervals of once per second. The fourth status LED blinks at a corresponding once-per-second
rate during normal operation and the third status LED flashes at a rate of once every 10 seconds
to indicate hardware connectivity. If the operating system fails to contact the Fault Monitor
Module at the regular interval, the FMM begins to restart the operating system after about 4
minutes. The watchdog timer waits for 15 minutes after the initial system startup to verify that
the operating system is functioning.
Shutdown button
The Fault Monitor Module also monitors the Shutdown button located on the front of the ISC1.
If the button has been pressed, the Fault Monitor Module signals the operating system to
perform a shutdown procedure. All operating system anomalies are sent as error messages to
the error-trace log by the Fault Monitor Module.
Fans/power supply status bits
The FMM checks the status of the power supply tray once per second. If there is a failure, an
error message is sent to the error-trace log and an SNMP alarm is generated.
