The EPS-500 power supply provides up to 500 W of total power and up to 375 W of power dedicated to
PoE applications. When this power supply is used with one of the listed Summit switches, the internal
and external power supplies are fully fault tolerant and load-sharing. If one power supply fails, the
other power supply will provide sufficient power to operate the switch.
The front of the EPS-500 has a green LED to indicate operating status
