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 (
Table 33
).
NOTE
An AC power input cord is not provided; you can order an appropriate cord from Extreme Networks or from
your local supplier. The power cord must meet the requirements listed in
“Selecting Power Supply Cords” on
page 339
.
Each EPS-500 power supply is shipped with a special redundant power supply cord (
Figure 83
).
