command. To initially activate PoE, you must use the
described above.
Disabling PoE
To disable PoE on a particular port, use the
-> lanpower port 1/1/12 admin-state disable
To disable PoE for all PoE-capable ports in a slot, use the
-> lanpower slot 1/1 service stop
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 allowed ranges.
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
command. Since you are setting the power allowance for an individual port, you must specify chassis/slot/
port values in the command line. For example, the syntax
-> lanpower port 1/1/24 power 3000
reduces the power allowance on port 24 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 slot
Like the maximum port power allowance, the system software also provides a maximum slot-wide power
allowance. By default, each slot is authorized by the system software to use a number of watts to power all
devices connected to its ports depending on which power supply is used.
As with the maximum port power allowance, the user can either increase or decrease this value based on
the allowed ranges.
Important. Decreasing the slot-wide power could cause lower priority ports to lose power if the new
value is less than the total PoE power currently being consumed.
To increase or decrease the total power available to a slot, use the
Since you are setting the power allowance for an individual slot, you must specify a chassis/slot value in
the command line. For example, the syntax
-> lanpower slot 3/1 maxpower 400
reduces the power allowance of chassis 3, slot 1 to 400 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).
