Planning Your PoE Configuration
Planning and
Implementation for the
Series 5400zl Switch
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 IEEE
802.3af-compliant devices require (use maximum power in watts, usually
found on a product’s data sheet). Adjust this total maximum power figure by
adding 15% to account for possible line loss. This value must be less than the
maximum power available shown in the table for your configuration.
