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.
Unsupported—Indicates that a 600/900 W AC PSU is inserted in a chassis other than the BlackDiamond 8806.

Modular switches only:

Located next to the “State” of the power supply, the following information provides more detailed status information. Options are:

PartInfo—Provides information about the power supply. Depending on your switch, options include:
Serial number—A collection of numbers and letters, that make up the serial number of the power supply.
Part number—A collection of numbers and letters that make up the part number of the power supply.

On modular switches, the output also includes the following information:

Revision—Displays the revision number of the power supply.
Odometer—Specifies how long the power supply has been operating.
Temperature—Specifies, in Celsius, the current temperature of the power supply.
Input—Specifies the input voltage and the current requirements of the power supply and whether the input is AC or DC.
Output 1 and Output 2—Specifies the output voltage and the current supplied by the power supply. The values are only displayed if known for the platform.

Summit family switches only:

Internal Power Supply (PowerSupply 1 information)—The Summit family switches come with one power supply pre-installed at the factory. The Summit 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 Summit family switches to protect against a power supply failure.

The Summit X460, E4G-400, BlackDiamond X8 series, and the BlackDiamond 8800 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 powersupplies {detail} command to view detailed health information about the power supplies.

Example

Modular switch example:

The following example displays the status of the power supply installed in slot 1 in a modular switch:

show power 1

The following is sample output from this command:

PowerSupply 1 information:
State:          Powered On
PartInfo:       PS 2336 5003J-00479 4300-00137
Revision:       2.0
Odometer:       90 days 5 hours
Temperature:    29.0 deg C
Fan 1:          6473 RPM
Fan 2:          6233 RPM
Input:          230.00 V AC
Output 1:       48.50 V,  7.25 A   (48V/1104W Max)
Output 2:       12.44 V,  0.62 A   (12V/48W Max)

If power management needs to disable a power supply to maximize the total available power, you see Disabled for net power gain next to the state of the power supply, as shown in the sample truncated output:

PowerSupply 1 information:
State:          Powered Off (Disabled for net power gain)
PartInfo:       PS 2336 0413J-00732 4300-00137
...

If you choose to always enable a power supply, regardless of the affect on the total available power, you see Configured ON next to the state of the power supply, as shown in the sample truncated output:

PowerSupply 1 information:
State:          Powered On  (Configured ON)
PartInfo:       PS 2336 0413J-00732 4300-00137

If you install the 600/900 W AC PSU in a chassis other than a BlackDiamond 8806, you see unsupported next to the state of the power supply, as shown in this sample truncated output:

PowerSupply 3 information:
State:          Unsupported
PartInfo:       PS 2431 0622J-00013 4300-00161

Summit family switches example:

The following command displays the status of the power supplies installed in the Summit X440 series switch:

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 for the Summit X440 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

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} .

The output was modified to include power management details for modular switches in ExtremeXOS 11.3.

DC power output for the BlackDiamond 8800 series switches was added in ExtremeXOS 11.4.

For the BlackDiamond X8 switch, the command output was enhanced to show the power supply groupings in ExtremeXOS 15.1.

Platform Availability

This command is available on all platforms.
