PoE Operational Status
Enabling PoE
By default, PoE is administratively enabled in the switch’s system software. However, in order to
physically activate PoE, you must issue the lanpower slot service command on a slot-by-slot basis
before any connected devices will receive inline power.
To activate power to PoE-capable in a switch, enter the corresponding slot number only. For example:
-> lanpower slot 2/1 service start
If power to a particular port has been administratively disconnected, you can reactivate power to the
port using the lanpower port admin-state command. For example:
-> lanpower port 2/1/1-24 admin-state enable
Note. You cannot use the lanpower port admin-state command to initially
activate PoE on a port. This syntax is intended only to reactivate power to those
that have been disconnected via the lanpower slot service command. To
initially activate PoE, you must use the lanpower slot service command as
described above.
Disabling PoE
To disable PoE on a particular port, use the lanpower port admin-state command. For example:
-> lanpower port 1/1/12 admin-state disable
To disable PoE for all PoE-capable ports in a slot, use the lanpower slot service command. For example:
-> 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.
This value can be increased or decreased based on the allowed ranges.
Increasing the total power available to an individual port may provide a more demanding powered
device 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 lanpower power
command.
Note. Since the power allowance is being set for an individual port, chassis/
slot/port values must be specified.
