Supported Products
The HP ProCurve Switch 2600-PWR Series devices and the HP ProCurve
Switch xl PoE Module support any products that meet the IEEE 802.3af PoE
standard.
Number of PDs per Switch
The number of PDs supported per switch depends on the power allocation
and how much power each PD uses and how much power is left. The following
examples show the power consumption in some typical configurations.
Planning Your PoE Configuration
This section assists you in building a reliable and, if required, redundant PoE
configuration. Using the following examples you can plan, build, and connect
your PoE devices quickly and easily.
There are three configurations: one for the HP ProCurve Switch 2626-PWR,
one for the HP ProCurve 2650-PWR, and one for the HP ProCurve Switch xl
PoE Module. Each shows a complete configuration including an optional HP
600 RPS/EPS unit. A table shows the PoE power available to connected PoE
devices when using just the switch or when using the switch and the HP 600
RPS/EPS unit. The tables show the available power when the HP 600 RPS/EPS
unit is providing PoE power to one or two devices.
Once you have selected your specific configuration and the PoE power
provided, you then add up the maximum amount of power each of your IEEE
802.3af-compliant devices require (use maximum power in watts, usually
found on a product’s data sheet). Adjust this total maximum power figure by
adding 15% to account for possible line loss. This value must be less than the
maximum power available shown in the table for your configuration.
If you are planning to include redundant power in your configuration you need
to determine which PoE devices must receive redundant PoE power, then total
their power requirements as explained in the paragraph above. The maximum
power figure must be less than the maximum power available when the switch
is powered by the HP 600 RPS/EPS unit, taking into consideration the number
of switches the HP 600 RPS/EPS unit is powering (one or two).
