Planning and Implementation for the HP 2520 and HP 2520G Switches
Planning the PoE Configuration
HP 2520-24-PoE and HP 2520G-24-PoE Configurations
The table in the example configuration contain entries that show the PoE
power available when the HP 2520-24-PoE or HP 2520G-24-PoE Switch is used
to supply PoE power.
Figure 3-2. Example of an HP 2520-24-PoE or HP 2520G-24-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.
