Planning and Implementation for the HP 3500-PoE yl Switches
Planning the PoE or PoE+ Configuration
sheet). Adjust this total maximum power figure by adding 16% to account for
possible line loss. This value must be less than the maximum power available
shown in the table for your configuration.
HP 3500-24G-PoE yl Switch Configuration
The table in this example configuration contains entries that show the PoE
power available for the HP 3500-24G-PoE yl Switch.

Note: If any of the mini-GBIC ports are used (21-24) the corresponding RJ-45
port will not be supplied with PoE power. Therefore that needs to be taken
into consideration when planning per port PoE wattage.
If for example, port 24 is used for a mini-GBIC, then the RJ45-port 24 is
disabled. Therefore the PoE power that was being supplied to the RJ45-port
24 is returned to the total available pool of PoE power.
All 24 ports can receive up to 15.4
watts of PoE power
