Reference Guide

PoE also provides a global usage threshold feature in order to limit the PoE switch from reaching an
overload condition. The operator can specify the limit as a percentage of the maximum power.
Note
PoE commands are only applicable to copper ports.
poe
Use this command to enable/disable PoE admin mode. If enabled, all ports (Interface Config mode) or
the selected port (Interface Config mode) are capable of delivering power to a PD (powered device). If
disabled, none of the ports can deliver power to a PD.
Note
PoE admin mode does not impact the functionality of the Ethernet port itself; disabling admin
mode only turns o the capability to deliver power.

poe detection
Use this command to set the detection mode. Detection mode is used to set the type of devices that
will be allowed for powering up. You can configure the PoE controller to detect only IEEE standard
devices or pre-IEEE legacy devices (which were pre-standard). Use the no form of the command to
bring detection mode back to the default setting of auto.

Format poe detection {auto | ieee | pre-ieee}

Parameter Description
auto Detects both standard and non-standard devices.
ieee Detects IEEE standard devices.
pre-ieee Detects legacy devices.
poe high-power
Use this command to enable high power mode for all ports in all units (Global Configuration) or for a
specific unit (Interface Configuration mode). In high power mode, the switch negotiates the power
budget with the powered device (PD). A PoE port can deliver up to 32 W of power in dot3at mode.
