Determining Which Power Supply Failed; Setting The Threshold For Power Supply Monitoring; Clearing Power Supply Failure Timestamps - Brocade Communications Systems MLX Series Installation Manual

Replacing a power supply
If you are hot-swapping a module, power supply, or fan tray, allow a minimum of two seconds after a
module (or power supply or fan tray) has been removed before inserting a module in the same slot.

Determining which power supply failed

To determine which power supply has failed, enter the show chassis command at any CLI command prompt.
Brocade# 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
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.
Brocade(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 MLX Series and Brocade NetIron Family Configuration
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.
Brocade(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.
Brocade(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
