The table in the example configuration contain entries that show the PoE
power available when the HP 2520-8-PoE or HP 2520G-8-PoE is used to supply
PoE power.
Figure 3-1. Example of an HP 2520-8-PoE or HP 2520G-8-PoE Switch
If any of the mini-GBIC ports are used the corresponding RJ-45 port will not
be supplied with PoE power. This needs to be taken into consideration when
planning per-port PoE wattage.
8 ports can receive up to
8 watts of PoE power
8 ports can receive up to
7.5 watts of PoE power
