Planning and Implementation for the HP 2615 and HP 2915G Switches

PoE Provisioning

The 2615-8-PoE and 2915-8G-PoE Switches provision ports 1-8 with 67 watts

of power for PoE applications compatible with the IEEE 802.3af standard.

Note There is no external power supply (EPS) available for these switches.

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 2615-8-PoE Switch with Gigabit Uplink

■ HP 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.
