The EPS-C2 system is compatible with the following switch models:

• 240-32t-16mt-10GE6 switch
The EPS-C2 system provides redundant power for up to
five switches. Redundant power connectors on
the rear panel of the EPS-C2 chassis are specific to the supported switch type; a selection switch
toggles between the connector type. Five 2x7 connectors are used to deliver power to the switches.The
EPS-C2 system connects to 240 series switches using a 2x9 connector.
The EPS-C2 system provides redundant power for up to five X440 series switches or for a single
X450e-48p or X250e-48p switch. Redundant power connectors on the rear panel of the EPS-C2 chassis
are specific to the supported switch type; a selection switch toggles between the connector type. Five
2x7 connectors are used for the X440 switches, and one 2x9 connector for the other switch models.
The 750 W AC PoE PSU used on the EPS-C2 has two power rails: 12V and PoE. These two power rails
are independent. If the PoE rail overloads, it will shut down all PoE but the 12V rail will continue to
function. If the 12V rail overloads, the 12V shuts down and the PoE rail will continue to function.
One redundant 2x7 power cable is shipped with the EPS-C2 chassis to provide the connection between
the external power system and the redundant power input connector on the back of a switch.
Additional redundant power cables are available from Extreme Networks.
