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

Planning and Implementation for the HP 5400R zl2 Switches
Configuration Examples
All three modules can be used or six and a half modules (134 ports) at 7.5 watts
per port.
Two power supplies could be used to supply PoE power at 508 watts and the
other two power supplies could be held in reserve as redundant power
supplies if the primary power supplies fail. If two power supplies are
connected to different power sources, they could backup the other two in case
of failure. With this option the user must manage the PoE usage in order to
maintain redundancy.
