disable inline-power

disable inline-power [{fast {ports [port_list | all]}} | perpetual]

Description

Disables PoE, and perpetual PoE to all ports; or fast PoE to all ports, or selected ports, for some platforms.

Syntax Description

fast Disables delivery of PoE power to devices at the time of switch power on without waiting for boot up based on last saved PoE state. The default is disabled.
ports For fast PoE, specifies selecting ports. ExtremeSwitching 5320, 5420, 5520, and 5720 series switches only.
port_list For fast PoE, specifies the port list separated by a comma or -. ExtremeSwitching 5320, 5420, 5520, and 5720 series switches only.
all For fast PoE, specifies selecting all ports. ExtremeSwitching 5320, 5420, 5520, and 5720 series switches only.
perpetual Disable preserving PoE power delivery to devices during reboot. Perpetual PoE is a switch-wide setting. The default is disabled.

Default

By default:
  • PoE is enabled.
  • Fast PoE is disabled.
  • Perpetual PoE is disabled.

Usage Guidelines

You can control whether inline power is provided to the system by using the disable inline-power command and the enable inline power command. Using the disable inline-power command shuts down inline power currently provided on the entire switch or to specified ports and slots. Disabling inline power to a switch, port, or slot immediately removes power to any connected PDs. By default, inline power provided to all ports is enabled. Additionally, you can disable delivery of PoE power to devices at the time of switch power on without waiting for boot up (fast PoE) based on last saved PoE state. Per-port fast PoE is available on certain platforms. You can also elect to not preserve PoE power delivery to devices during reboot (perpetual PoE). The default for both PoE options is disabled.

Note

Note

Disabling inline power using the disable inline-power command does not affect the data traffic traversing the port. And, disabling the port using the disable port command does not affect the inline power supplied to the port.
Note

Note

Inline power cannot be delivered to connected PDs unless the switch is powered on.

Example

The following command shuts down inline power currently provided to all ports and all slots:

disable inline-power
The following example turns off perpetual PoE for the switch:
# disable inline-power perpetual

The following example turns off fast PoE for ports 1,2, and 5:

# disable inline-power fast ports 1,2,5
