HP Power over Ethernet (PoE/PoE+) Planning and Implementation Guide

If redundant PoE power is required, use the example tables to determine how
much power is available to which ports.
Figure 5-4. Example of an HP 600 RPS/EPS Powering One HP 2610-48-PoE Switch
The lowest loaded bank of ports (1-24 or 25-48) has 22 watts reserved. That
power is available for use by the two highest priority ports in the bank, (in a
default configuration ports 1 and 2, or 25 and 26).
