Planning And Implementation For The Switch Xl Poe Module; Planning Your Poe Configuration - HP ProCurve 2520 Planning And Implementation Manual

Planning and Implementation for the Switch
xl PoE module
This chapter discusses the planning process a user should follow to
successfully implement PoE using a Series 5300xl PoE module. After
understanding what PoE is and its operating rules, the next step to
implementation is planning. See
example list of considerations during the planning phase.

Planning Your PoE Configuration

This section assists you in building a reliable PoE configuration. Using the
following examples you can plan, build, and connect your PoE devices quickly
and easily.
Your configuration may vary however this section discusses some of the more
common configurations.
There are five configurations:
■
■
■
■
■
Each example shows a complete configuration using either a 600 RPS/EPS or
610 EPS unit. A table shows the PoE power available to connected PoE devices
Once you have selected your specific configuration and the PoE power
provided, you then add up the maximum amount of power each of your IEEE
802.3af-compliant devices require (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.
One module with a 600 RPS/EPS
Two modules with a 600 RPS/EPS
Two modules with a 610 EPS using a separate pair of power ports
Two modules with a 610 EPS using the same pair of power ports
Four modules with a 610 EPS
