Figure 4-10. Example of a 5412zl with four power supplies, J8712A
In this example there are four power supplies supplying 273 watts each for a
maximum of 1092 watts.
All three modules can be used or six and a half modules (156 ports) at 7.0 watts
per port.
Or, two power supplies could be used to supply PoE power at 546 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.
71 ports can receive up to
15.4 watts of PoE power
