Planning and Implementation for the HP 2610-PoE Switches
Planning the PoE Configuration
■ The internal power supply can provide up to 126 W of power to be used on all
12 PoE ports. The power can be allocated up to the maximum of 12 ports, or
126 W, whichever is depleted first with a reserve of 22 W maintained by the
switch for power management. If more power is needed to allow the
maximum of 15.4 W on all 12 ports, an external power supply accessory is
needed.
■ Also (not shown), two HP 2610-24-PPoE Switches with a dedicated HP 600
RPS/EPS unit has full redundant PoE power for both switches. The HP 600
RPS/EPS supplies 408 watts to one switch and 204 watts to each switch when
two switches are connected to the HP 600 RPS/EPS.
HP 2610-24-PoE Switch Configurations
The tables in the example configurations contain entries that show the PoE
power available when the HP 2610-24-PoE Switch is used alone. When used
with the HP 600 RPS/EPS or HP 610 EPS unit, PoE power is available to the
PoE ports should the internal PoE power supply fail. Table entries show the
PoE power available when the HP 600 RPS/EPS or HP 610 EPS alone provides
PoE power.
