Configuring Power over Ethernet Parameters

Configuring the Total Power Available to a Port

By default, each port is authorized by the system software to use up to a maximum amount of milliwatts to
power any attached device.
You can either increase or decrease this value based on the range in the specifications table.
Increasing the total power available to an individual port may provide a more demanding Powered Device
(PD) with additional power required for operation. Decreasing the total power available to a port helps to
preserve inline power and assists in the overall management of the switch's power budget.
To increase or decrease the total power available to an individual port, use the
Since you are setting the power allowance for an individual port, you must specify a slot/port number in
the command line. For example, the syntax
-> lanpower 1/1 power 3000
reduces the power available on port 1 of the switch to 3000 milliwatts. This new value is now the
maximum amount of power the port can use to power any attached device (until the value is modified by
the user).

Configuring the Total Power Available to a Switch

Like the maximum port power allowance, the system software also provides a maximum slot-wide power
allowance. By default, each switch is authorized by the system software to use up to the maximum watts
available from the PoE power supply.
As with the maximum port power allowance, the user can either increase or decrease this value based on
the range in the specifications table.
Increasing the total power available to a switch may provide more demanding Powered Devices (PDs)
with additional power required for operation. Decreasing the total power available helps preserve inline
power and assists in the overall management of the switch's power budget.
Important. Before changing the maximum slot-wide power allowance, you must disable PoE for the slot
via the lanpower stop
lanpower start command.
To increase or decrease the total power available to a slot, use the
you are setting the power allowance for an individual slot, you must specify a slot number in the command
line. For example, the syntax
-> lanpower 1 maxpower 40
reduces the power allowance of slot 1 to 40 watts. This value is now the maximum amount of power the
slot can use to power all attached devices (until the value is modified by the user).
Note. Changing the maximum power available to a slot or port does not reserve or immediately allocate
that power. These settings are only used for configuring a maximum amount of power that may be used,
any unused power is still available and remains a part of the overall PoE budget.
