EPS-600LS External Power Module
The EPS-600LS External Power Module (Model 10913) is a 600-watt redundant power supply unit that
can be used with the following Extreme Networks switches:
•
Summit X450e-48p switch
•
Summit X250e-48p switch
You install one, two, or three EPS-600LS power modules in the EPS-C chassis (Model 10912) to build an
external redundant power system for the Summit switch. A redundant power cable shipped with the
EPS-C chassis provides the connection between the external power system and the redundant power
input connector on the back of the switch.
LEDs on the front panel of the EPS-C indicate operating status for the installed EPS-600LS modules as
shown in the following table.
Label
DC Good
(PSU1, PSU2, and PSU3)
AC Good
(PSU1, PSU2, and PSU3)
Note
An AC power input cord is not provided with the EPS-600LS power module. You can order
an appropriate cord from Extreme Networks or from your local supplier. The power cord
must meet the requirements listed in
and AC Power
Each EPS-C chassis is shipped with a special redundant power supply cord for connection to the
Summit switch. Make sure that the EPS-C chassis is installed in the equipment rack before installing an
EPS-600LS power module.

PoE Redundant Power Configurations

The PoE capability of the Summit X450e-48p or X250e-48p varies depending on the number of
external power modules in use.
The following table summarizes the PoE power behavior for the Summit X450e-48p or X250e-48p
switch based on the number of power modules in use.
