Planning and Implementation for the HP 5400R zl2 Switches
Configuration Examples
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 5406R zl2 Configurations
The table in each example configuration contains entries that show the PoE
power available for the PoE modules.
In this example there is one J9828A power supply supplying 275 watts for PoE
usage.
