Article ID: KB26582 KB Last Updated: 14 Nov 2020Version: 2.0
Summary:

This article provides information about the reasons that could trigger the power supply functioning/not functioning properly alarms in event logs.

 

Symptoms:

 The following alarms are generated in event logs:

2011-01-21 11:20:15 system crit 00022 The power supply 1 is functioning properly.
2011-01-21 11:20:11 system crit 00022 The power supply 1 is not functioning properly.

 

Solution:

The above events are generated, when the power to the power supply is interrupted.

For example:

  • When power supply was turned off, the following event was generated:

    2012-11-21 11:20:11 system crit 00022 The power supply 1 is not functioning properly.
  • Then, when the power supply was turned on, the following event was generated:

    2012-11-21 11:20:15 system crit 00022 The power supply 1 is functioning properly.

So, the reason can be fluctuating power interruption to the power supply, due to which the above events are generated. It is good to check for any loose connections to the power supply or any power related issues in the rack on which the device is mounted.

When you have validated that there are no power related issues in the rack/switch, which is supplying power to the power supply, no loose connections, or no external power issues and the above event logs are still generated, then it may be a hardware issue with the power supply and the RMA of the power supply can be initiated.
