Planning and Implementation for the HP 5400zl/8200zl Switches
Configuration Examples
Figure 13-16.Example of an HP 5412zl Switch with four power supplies, J8713A
This configuration (Figure 13-16) is an example of four power supplies
supplying 900 watts each for a maximum of 3600 watts to a fully-loaded HP
5412zl Switch with 288 ports. Therefore out of the total 288 available ports,
233 can be powered at 15.4 watts each.
Two power supplies could be used to supply PoE power at 1800 watts and the
other two power supplies could be used as secondary power supplies. If the
two sets of power supplies are connected to different power sources, one set
of two could backup the other two in case of failure. With this option the user
must manage the PoE usage in order to maintain redundancy.
