Installation Guide

This command displays status information for the fans and power supplies, and temperature readings for various components in the
device. The power supplies are numbered in the display. Refer to Displaying device status and temperature readings on page 204 for
more information.
If a power supply has failed, the display indicates "Installed (Failed)" and identies the slot in which the failed power supply is installed.
Setting the threshold for power supply monitoring
The power-supply monitoring threshold command monitors the power supply state, and indicates when a power supply will shut down
due to failure.
To set a threshold value for power supply monitoring, enter the following command.
device(config)#power-supply monitoring threshold 3
A Power Supply will be Shutdown if it fails 3 times within an Hour
The power supply will ap three times within an hour, after which the power supply will automatically shut down.
Syntax: [no] power-supply monitoring [ threshold decimal ]
The decimal variable species the number of aps within an hour after which a power supply will automatically shutdown. The threshold
range is from 0 through 32. The default value is 5. A value of 0 disables the power supply auto-shutdown on apping.
NOTE
A threshold value of 0 will not automatically shutdown a power supply due to failures.
For Syslog messages, please refer to Appendix A, Using Syslog in the Extreme NetIron Management Conguration Guide.
Clearing power supply failure timestamps
Use the power-supply monitoring clear command to clear all collected failure timestamps for a given power supply, or for all available
power supplies.
To clear all collected failure timestamps for a power supply, enter the following command.
device(config)# power-supply monitoring clear 1
This will clear all collected failure timestamps for the Power Supply # 1
Are you sure? (enter 'y' or 'n'): y
To clear all collected failure timestamps for all available power supplies, enter the following command.
device(config)# power-supply monitoring clear all
This will clear all collected failure timestamps for all available Power Supplies
Are you sure? (enter 'y' or 'n'): y
You are asked to verify this command by entering "yes" or "no".
Syntax: power-supply monitoring clear decimal | all ]
By default, no power-supply monitoring is
congured.
The decimal variable species a power supply number, The all keyword clears all available power supplies.
Displaying power supply monitoring timestamps
To display timestamps for failures on any power supply, enter the following command.
device#show power-supply-monitoring
PS-1 PS-2 PS-3 PS-4
