When a powered device (PD) is initially connected to a PoE port, a minimum
of 15.4 watts of available power is required to begin the power-up sequence.
This 15.4 watts is needed to determine the type of PD requesting power. Once
the power classification is determined and power is supplied, any power
beyond the maximum power requirements for that class of PD is available for
use by other ports.
In the default switch configuration all PoE ports have a Low priority. If the
switch has less than 15.4 W of PoE power available, the switch transfers power
from lower-priority ports to higher-priority ports. Within each priority class, a
lower numbered port is supplied power before a higher numbered port. For
more information refer to "Power over Ethernet (PoE) Operation" in the
Management and Configuration Guide
Disconnecting a PD from a port causes the switch to stop providing power to
that port and makes that power available to other ports configured for PoE
operation. For more information on PoE power requirements refer to the HP
ProCurve PoE Planning and Implementation Guide that came with your HP
600 RPS/EPS or HP 610 EPS.
