Planning and Implementation for the

2615 and 2915G Switches

This chapter discusses the planning process a user should follow to

successfully implement PoE using a 2615 or 2915G Switch. After

understanding what PoE is and its operating rules, the next step to

implementation is planning. See “General Considerations” page A-1, for an

example list of considerations during the planning phase.

Planning the 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 two configurations:

■ HP ProCurve 2615-8-PoE Switch with Gigabit Uplink

■ HP ProCurve 2915-8G-PoE Switch

Each example shows a complete configuration. 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.
