show power

show power {ps_num} {detail}

Description

Displays the current status of the installed power supplies.

Syntax Description


`ps_num`	Specifies the slot number of the installed power supply.
detail	The detail option is reserved for future use.

Default

N/A.

Usage Guidelines

Use this command to view detailed information about the health of the power supplies.

This status information may be useful for your technical support representative if you have a network problem.

The switch collects the following power supply information:

State—Indicates the current state of the power supply. Options are:
- Empty—There is no power supply installed.
- Power Failed—The power supply has failed.
- Powered Off—The power supply is off.
- Powered On—The power supply is on and working normally.

Disabled for net power gain—Indicates that the power supply is disabled in order to maximize the total available system power.
Configured ON—Indicates that the user requested to enable a disabled power supply regardless of the affect on the total available system power.
Configured ON when present—Indicates that the power supply slot is currently empty, but the user requested to enable the power supply regardless of the affect on the total available system power.

Internal Power Supply (PowerSupply 1 information)—The ExtremeSwitching switches come with one power supply pre-installed at the factory. The ExtremeSwitching power supply is not user-replaceable; therefore, the part information display indicates internal power supply.
External Power Supply (PowerSupply 2-4 information)—Displays information about the optional External Power System (EPS) that allows you to add a redundant power supply to the ExtremeSwitching seres switches to protect against a power supply failure.

The ExtremeSwitching series switches include Power Usage, which is only an estimate for the input power consumed. SummitStack displays the supplies associated to each active node that is present in a slot. The supplies are represented with flags that describe whether the supply is providing power, has failed, or is providing no power, or if the supply has had its 48v power output automatically turned off because two or three external power supplies are available. For more information, see show power (Stack Nodes Only).

In ExtremeXOS 10.1 and earlier, use the show power supplies {detail} command to view detailed health information about the power supplies.

In ExtremeXOS 22.5 and later, the detail option shows external power supply fan airflow direction. This is only applicable for switches that support such power supplies:

ExtremeSwitching 5320—all models
ExtremeSwitching 5420—all models
ExtremeSwitching 5520—all models
ExtremeSwitching 5720—all models

Bridge Port Extenders (BPEs)

Power supply information for bridge port extenders (BPEs) does not appear in this command. Use the show vpex bpe {slot slot_num} {environment} command instead.

Example

The following command displays the status of the power supplies installed:

# show power

The following sample output assumes that you have not installed an EPS:

PowerSupply 1 information:
State:          Powered On
PartInfo:       Internal Power Supply
PowerSupply 2 information:
State:          Empty

The following sample output assumes that you have installed an EPS:

PowerSupply 1 information:
State:          Powered On
PartInfo:       Internal Power Supply
PowerSupply 2 information:
State:          Powered On
PartInfo:       External Power Supply

The following sample output assumes a connection to an external EPS-C with three EPS-600LS modules installed:

# show power
PowerSupply 1 information:
State:          Powered Off
PartInfo:       Internal Power Supply
Input:          0.00 V AC
PowerSupply 2 information:
State:          Powered On
PartInfo:       External Power Supply
Input:          0.00 V AC
PowerSupply 3 information:
State:          Powered On
PartInfo:       External Power Supply
Input:          0.00 V AC
PowerSupply 4 information:
State:          Powered On
PartInfo:       External Power Supply
Input:          0.00 V AC

For stacking systems, the power detail display is enhanced as follows:

# show power

History

This command was first available in an ExtremeXOS 10.1.

The syntax for this command was modified in ExtremeXOS 11.0 from show powersupplies to show power {ps_num} {detail} .

Power supply fan airflow direction information was added in ExtremeXOS 22.5.

Platform Availability

This command is available on all Universal switches supported in this document.
