DFM and Redundant Power

Can DFM alert if RPS fails?

For example I have a 3750 stack of 6 switches on one RPS2600. If the RPS fails or looses power but the 3750s are OK running on their primary power, can I get an alert?

Re: DFM and Redundant Power

I don't have a 3750 with an RPS which which to test, but if you go to DFM > Device Management > Device Details and launch the Detailed Device View for this switch, do you see any Power Supply objects under the Environment folder?

I see the primary power supply status (all 6 from the stack) but there is no redundant status.

Re: DFM and Redundant Power

The state should change to critical when the main PS switches to the RPS. This will trigger an event in DFM.

Re: DFM and Redundant Power

I was hoping to get an alert if the RPS lost power. Last week I discovered a power cord for RPS supplying backup power for 6 3750 switches was unplugged. It would be nice if there was a way to be alerted if the RPS is not available even if the 3750s have primary power.

Re: DFM and Redundant Power

Based on your SNMP output, it does not appear the 3750s have the instrumentation to provide such data.
