Hp Procurve 3500Yl-24G-Pwr Configuration - HP ProCurve 2520 Planning And Implementation Manual

Planning and Implementation for the 3500yl Switches
Planning Your PoE or PoE+ Configuration
Each example shows a complete configuration. A table shows the PoE or
PoE+ power available to connected PoE or PoE+ devices when using just the
switch or when connecting to an external power supply.
Once you have selected your specific configuration and the PoE or PoE+
power provided, you then add up the maximum amount of power each device
requires (use maximum power in watts, usually found on a product's data
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 ProCurve 3500yl-24G-PWR Configuration

The table in this example configuration contains entries that show the PoE
power available for the 3500yl-24G-PWR.
Figure 9-1. Example of a 3500yl-24G-PWR Switch
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.
