Planning And Implementation For The 3500 Switches; Planning Your Poe Configuration - HP ProCurve 2520 Planning And Implementation Manual

Planning and Implementation for the 3500
Switches
This chapter discusses the planning process to follow to successfully
implement PoE on a 3500 switch. After understanding PoE and its operating
rules, the next step to implementation is planning. See
Considerations" page A-1,
planning phase.

Planning Your PoE Configuration

This section assists you in building a PoE configuration. Using the following
examples you can plan, build, and connect PoE devices quickly and easily.
There are four configurations for the HP ProCurve 3500:
■
■
■
■
Each example shows a complete configuration. A table below the
configuration shows the PoE power available to connected PoE devices when
using just the switch.
Once you have selected your specific configuration and the 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.
