Release Information Statement introduced in Junos OS Release 9.0 for EX Series switches.

Statement introduced in Junos OS Release 12.2 for ACX2000 Universal Access Routers.

Statement introduced in Junos OS Release 17.2R1 for a Junos Fusion Provider Edge.

Description Designate how the PoE controller allocates power to the PoE interfaces.

Default class

Options • class—The amount of power allocated to the interface is determined by the class of

the connected powered device. If no powered device is connected, standard 15.4 W

power is allocated to the interface. See Understanding PoE on EX Series Switches for

more information about classes of powered devices.

• static—The amount of power allocated to the interface is determined by the value of

the maximum-power statement, not the class of the connected powered device. This

amount is allocated even when a powered device is not connected to the interface,

ensuring that power is available when needed.

• high-power—(ACX2000 routers only) ACX2000 PoE interfaces support power delivery

of up to 65 W per port using all four pairs of Ethernet RJ45 cables. Traditional PoE

ports use only two pairs of Ethernet cable for power delivery. According to the IEEE

802.3af standard, each port can deliver a maximum power of up to 32 W. With

high-power mode of power delivery over all four pairs, the power sourcing equipment

(PSE) has an option to deliver up to 65 W per port, provided the powered devices

request this high power over all four pairs of the Ethernet cable. By default, high-power

mode is not enabled and has to be explicitly enabled. When the PoE controller is

configured for high-power mode, the PoE controller does not deliver power to normal

powered devices that request power over two pairs.
