Planning and Implementation for the 5400zl/8200zl Switches

Configuration Examples

Planning and

Implementation for the

5400zl/8200zl Switches

Figure 10-15.Example of a 5412zl with three power supplies, J8713A

This configuration (Figure 10-15) 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 7.5 watts.

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.
