Installing the Switch
Installation Procedures
In this example each switch receives 408 watts of PoE power. Each switch is
connected to one port of each pair. If the two switches were connected to both
ports of a pair, both ports of pair A for example, then each switch receives 204
watts. See the following example.
The following illustration demonstrates an example of connectivity between
a 610 EPS device and four Switch devices as a PoE power supply. In this
example each switch receives 204 watts of PoE power.
