Planning and
Implementation for the
Series 5400zl Switch
Example of a 5412zl with three power supplies, J8713A
This configuration is an example of three power supplies supplying 900 watts
each for a maximum of 2700 watts to a fully loaded chassis of 288 ports.
Therefore out of the total 288 available ports, 175 can be powered at 15.4 watts
each. That’s equal to a little over 6 and a half modules. Or all ports could be
used at 7.0 watts.
Or, two power supplies could be used to supply PoE power at 1800 watts and
the other one power supply could be held in reserve as redundant power
supply if one of the primary power supplies fail. However this configuration
cannot be fully redundant.
