HP ProCurve 2650-PWR Configurations

The tables in the example configurations contain entries that show the PoE
power available when the 2650-PWR is used alone. When used with the HP
600 RPS/EPS or HP 610 EPS unit, additional PoE power is available to the PoE
ports and PoE power is available should the switch's internal PoE power
supply fail. Table entries show the PoE power available when the HP 600 RPS/
EPS or the HP 610 EPS alone provides PoE power.
In the following examples using the HP ProCurve 2650-PWR switch, reference
is made to two blocks of ports: ports 1-24 and ports 25-48. This applies when
external PoE power is available from an HP 600 RPS/EPS or HP 610 EPS unit.
In that case, the internal switch PoE power supply provides 406 watts of power
to ports 1-24 and the HP 600 RPS/EPS or HP 610 EPS provides 408 watts of
power to ports 25-48.
If you are using the HP ProCurve Switch 2650-PWR with external PoE power,
the number of ports with available PoE power when the switch is powered by
just the HP 600 RPS/EPS or HP 610 EPS unit may be less than the number of
ports powered when both the switch and the HP 600 RPS/EPS or HP 610 EPS
unit are supplying power. In the default configuration the number and location
of ports with redundant PoE power is determined by three factors:
N o t e
It is the ports configured with the highest priority of either bank (1-24 or 25-
48) that will receive PoE power. For example, if the highest priority ports have
been re-configured to be 23, 24 and 47, 48, then they will have PoE power.
If redundant PoE power is required, use the example tables to determine how
much power is available to which ports.
The number of switches drawing external PoE power from the HP 600
RPS/EPS or HP 610 EPS unit. If only a single switch is using external PoE
power the HP 600 RPS/EPS or HP 610 EPS provides 408 watts of PoE
power. If two switches are using external PoE power from the HP 600
RPS/EPS or two switches are connected to the same pair on the HP 610
EPS, a switch receives 204 watts of PoE power. Should the switch's
internal PoE power supply fail, the HP 600 RPS/EPS or HP 610 EPS
provides power up to the wattage stated above.
When the internal PoE power supply fails, the HP 600 RPS/EPS reserves
a minimum of 38 watts for the less-loaded bank of ports. In the default
configuration, at a minimum, the first two ports in the bank (1 and 2 or 25
and 26) will have PoE power.
In the default configuration PoE power priority is determined by port
number, with the lowest numbered port having the highest priority.
