7 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 ] The 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 ] By default, no power-supply monitoring is configured. 164 PowerConnect B-MLXe Hardware Installation Guide 53-1002111-01

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:

[

]

power-supply monitoring

[

threshold

]

The

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

]

By default, no power-supply monitoring is configured.
