The default PoE values for ports sourcing PoE are listed here:
PoE is enabled.

The wiring configuration is Alternative A. (This parameter is not

adjustable.)
No further configuration steps are required for ports connected to the
following types of powered devices:
PoE or PoE+ devices that comply with PoE standards and support

both Alternatives A and B.
Legacy devices that only support Alternative A.

The above devices should now be receiving power from the ports on
the switch.
The procedure in this section explains how to verify and adjust, if
necessary, the provisioned or nominal PoE budget for IE340 PoE PSE
switches. This value is the maximum wattage the switch is expecting from
the power supply for the powered devices on its ports. The provisioned
budget should be the same as or less than the actual PoE budget from the
power supply. If the provisioned budget is above the actual budget, the
switch may experience problems. For instance, it may attempt to distribute
more power than it actually has available from the power supply or display
the PoE Status LEDs incorrectly.
The default nominal or provisioned PoE budget is 240W. The default value
corresponds to the maximum PoE budget for power supplies that meet the
specifications in "Power Supplies" on page 49. If you purchase a power
supply that does not meet the specifications, the actual PoE budget may
be less, in which case you should perform the following procedure to
adjust the provisioned budget to match the actual value.
To verify and adjust the maximum provisioned PoE budget for the switch,
perform the following
1. In the Privileged Exec mode, enter the SHOW POWER-INLINE
command:
awplus# show power-inline
2. Compare the Nominal Power and Power Allocated fields in the
command output. The Nominal Power field is the provisioned PoE
budget of the switch. It is the wattage the switch is expecting from the
power supply for PoE devices. The Power Allocated is the actual
wattage the switch is receiving from the power supply. The default
value for the provisioned budget is 240W.
