Planning and

Implementation for the

Series 5400zl Switch

ProCurve 5406zl Configurations

The table in each example configuration contains entries that show the PoE

power available for the PoE modules.

Figure 4-1. Example of a 5406zl with one power supply, J8712A

In this example there is one J8712A power supply supplying 273 watts for PoE

usage.

To achieve the 16 ports at 15.4 watts the PoE devices must be divided up and

connected to two different modules. Remember, as soon as a module is

installed into the switch, 22 watts is reserved for its use.

In order to use those watts, devices must be connected to that module or PoE

power must be disabled to all ports on that module.

If PoE power is disabled to all ports on a module the 22 watts that was reserved

for that module is returned to the pool of available watts and can be used by

another module’s ports.

14 ports on module A and 2 ports on module B

can receive up to 15.4 watts of PoE power
