Planning and Implementation for the 5400zl/8200zl Switches

Configuration Examples

Planning and

Implementation for the

5400zl/8200zl Switches

Figure 10-16.Example of a 5412zl with four power supplies, J8713A

This configuration (Figure 10-16) is an example of four power supplies

supplying 900 watts each for a maximum of 3600 watts to a fully loaded chassis

of 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.
