Planning and
Implementation for the
5400zl/8200zl Switches
Configuration Examples
In the following configuration examples, each example shows a complete
configuration. A table shows the PoE power available to connected PoE
devices when using just the switch and when connecting an external power
supply.
Once you have selected your specific configuration and the PoE power
provided, you then add up the maximum amount of power each of your
devices require (use maximum power in watts, usually found on a product’s
data sheet). Adjust this total maximum power figure by adding 16% to account
for possible line loss. This value must be less than the maximum power
available shown in the table for your configuration.
HP ProCurve 5406zl Configurations
The table in each example configuration contains entries that show the PoE
power available for the PoE modules.
Figure 10-2. Example of a 5406zl with one power supply, J8712A
In this example there is one J8712A power supply supplying 273 watts for PoE
usage.
14 ports on module A and 2 ports on module B
can receive up to 15.4 watts of PoE power
