HP ProCurve 2610-PWR Switches

Maximum PoE Power
The Switch 2610-24/12PWR provisions (allocates power to) ports 1-12 with
126 watts of power for PoE. The Switch 2610-24-PWR provisions ports 1-24
with 406 watts of power for PoE and the Switch 2610-48-PWR provisions ports
1-48 with 406 watts of power for PoE. This reduces the per port wattage by
half as compared to the Switch 2610-24-PWR. These switches support PoE
applications compatible with the IEEE 802.3af standard and some pre-
standard devices.
However, by connecting a 600 RPS/EPS or a 610 EPS, you can optionally
provision ports 25-48 on the 2610-48-PWR switch with 408 watts of external
PoE power, thereby bringing the per port wattage up to 15.4 watts per port,
unless you have the other EPS port of the 600 RPS/EPS or the other port of a
pair on the 610 EPS connected to a HP ProCurve PoE device. In this case you
cannot provision the full 408 watts to the Switch 2610-48-PWR, only half, or
204 watts.

* If both EPS ports on the 600 RPS/EPS or both ports of a pair on the 610 EPS are connected to switches, each switch
can receive 204 watts of power. If a single switch is connected to the EPS ports, that switch can receive 408 watts.
