Hello, I have both Cisco 4500 and Cisco 3600x, I've experienced a power outage a few days ago. The 4500 device didn't show anything on the System Health Power Supplies sensor and the 3600 device showed an error on the System Health Power Supplies sensor: System Health Power Supplies (SNMP Cisco System Health) Down (No such instance (SNMP error # 223)). After returning the power, the sensor refused to return to it normal and I had to recreate it. I want to add, even when I tried to simulate the power supply outage the problem repeated itself, the 4500 device showed no problem and the 3600 device entered into error mode and I had to recreate the sensor after the return of the power supply.
Is there another way to monitor the power supply and power outages ?
Thank you, Yaron
