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

13-41
Planning and Implementation for the HP 5400zl/8200zl Switches
Configuration Examples
Figure 13-19.Example of an HP 5412zl with four power supplies (two J8712A and two J8713A)
In this example (Figure 13-19) 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 288 ports can
be powered at 7.0 watts each.
Note HP networking highly recommends that the two types of power supplies are
not mixed in the same HP 5412zl Switch or HP 8212zl Switch.
The reason the redundant number of ports in this table is so low is because
redundant PoE power should always be based on the smallest power supply.
In this case the smallest power supply is the J8712A providing 546 watts.
