Power Over Ethernet (PoE) Operation
General PoE Operation
the lowest-priority port on the module loses PoE power and remains unpow-
ered until the module once again has 17 or more watts available. (For infor-
mation on power priority, refer to “Power Priority Operation” on page 11-10.)
Disconnecting a PD from a PoE port causes the module to stop providing PoE
power to that port and makes the power available to any other PoE ports that
have PDs connected and waiting for power. If the PD demand for power
becomes greater than the PoE power available, then power is transferred from
the lower-priority ports to the higher-priority ports. (Ports not currently
providing power to PDs are not affected.)
