Message: CI-2-ENVCRIT: +12 Voltage measured at X

[mkokosz]

Hello,

I get on C7500 (IOS 12.2(2)T4)

this messages in the logs every 5min:

%CI-2-ENVCRIT: +12 Voltage measured at 10.25

it started several weeks ago with last number just

below default warning threshold. Now it is below critical threshold.

I checked both power supplies, upgraded the IOS to 12.2(17), tried resetting (by unplugging it and plugging again) chassis interface. Error is still there and voltage is falling down.

Is this chassis interface (CI) failure or could it be something else?

Hi,

If you are sure your power supply unit is good, I feel that the problem could be with the chassis interface card. This is the card that collects the environmental information on the router.
