EPS-500 External Power Supply Unit
The Extreme Networks EPS-500 External Power Supply Unit (Model 10911) provides additional power
to compatible Power over Ethernet (PoE) switches and other Extreme switches. You can use the
EPS-500 power supply as a redundant power supply with the following Extreme Networks switches:
•
Summit X150-24p switch
•
Summit X250e-24p switch
•
Summit X350-24t switch
•
Summit X350-48t switch
•
Summit X450a-24t switch
•
Summit X450a-24x switch
•
Summit X450a-48t switch
•
Summit X450e-24p switch
•
Summit X450e-24t switch
•
Summit X450e-48t switch
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 as shown in the following table.
