Static PoE Management Mode
In the static PoE management mode, you specify the maximum power for each PoE interface. The PoE controller then allocates this amount of power to the interface from the maximum PoE power consumption for the switch or line card. For example, if you specify a maximum value of 8.0 W for ge-0/0/3, the PoE controller allocates 8.0 W for this interface out of the maximum power consumption. This amount is allocated to the interface irrespective of whether a powered device is connected to the interface or the connected powered device uses less power than 8.0 W.
Because of line loss, the power received by the powered device can be less than the power available at the PoE port. Table 8 shows the maximum power available at a PoE port and the resulting power guaranteed to the powered device.
