Replacing a power supply
PowerConnect# show chassis
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 102 for more information.
If a power supply has failed, the display indicates "Installed (Failed)" and identifies 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.
PowerConnect(config)#power-supply monitoring threshold 3
A Power Supply will be Shutdown if it fails 3 times within an Hour
The power supply will flap three times within an hour, after which the power supply will
automatically shut down.
Syntax: [no] power-supply monitoring [threshold <decimal>]
The <decimal> variable specifies the number of flaps 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 flapping.
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 Brocade NetIron
Configuration Guide.
Clearing power supply failure timestamps
The power-supply monitoring clear command is used 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.
PowerConnect(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.
PowerConnect(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 configured.
