Planning Your PoE Configuration
Figure 4-15. Example of a 5412zl with four power supplies (two J8712A and two
In this example there are two J8712A and two J8713A power supplies
supplying 2892 watts for PoE usage. With this configuration 187 ports (or more
than 7 modules) can be provisioned at 15.4 watts. Or all ports, 288 can be
powered at 7.0 watts each.
ProCurve Networking highly recommends that the two types of power
supplies are not mixed in the same 5412zl chassis.

The reason the redundant # of Ports in this table is so low if because redundant
PoE power should always be based on the smallest power supply. In this case
the smallest power supply is the 8712A providing 546 watts.
