Hello,
Is the SIM version 7.0.4 ? All events should be forwarded if you configured SNMP te send events. Does the IML show events about the powersupply ?
I don't think SIm would be 7.0.4, could be the System Management Homepage ? Does the System Management Homepage show the Powersuply. If i doesn't the SNMP agent could be faulty. What is your OS name Windows or Linux ?
