HP ProCurve 2600-PWR Switches

Maximum PoE Power

The Switch 2600-8-PWR provisions (allocates power to) 8 ports with its
internal PoE power supply of 126 watts for PoE applications compatible with
the IEEE 802.3af standard and some pre-standard PoE devices.The Switch
2626-PWR provisions ports 1-24 with 406 watts of power for PoE applications
compatible with the IEEE 802.3af standard. The Switch 2650-PWR provisions
ports 1-48 with 406 watts for PoE. This reduces the per port wattage by half
as compared to the Switch 2626-PWR.
However, by connecting a 600 RPS/EPS or a 610 EPS, you can optionally
provision ports 25-48 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 2650-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.
