FAQ

How Can I Determine Whether the Power Supply Status Is Abnormal?

The power supply status is abnormal in either of the following situations:
  1. Run the display power command to view the power supply status. If the State field displays NotSupply, the power module does not supply power. Check whether the power module is installed properly and whether the power switch is turned on.

     0       PWR2     Present  AC     NotSupply   150.00  
  2. Run the display device command to view the power supply status. If the Status field displays Abnormal, the power supply status is abnormal. You can run the display trapbuffer command to check whether there are any power supply alarms.
