●
Redundant power input connector for optional connection to the EPS-C chassis (Model No. 10912).
This chassis can hold up to three EPS-600LS External Power Modules (Model No. 10913). The
connecting redundant power supply cable is shipped with the EPS-C chassis.
The PoE capability of the Summit X450e-48p switch varies depending on the number of external
power modules in use. For more information, see
“Summit X450e-48p Power Supplies” on page 103
and “EPS-600LS External Power Module” on page 143 .
●
AC power input socket
The power supply operates from 100 VAC to 240 VAC.

Summit X450e-48p Power Supplies
The Summit X450e-48p switch is powered by both an internal power supply and an optional external
redundant power supply system.
Internal Power Supply. The internal Summit X450e-48p power supply can provide 370 W of PoE
power, as follows:
●
In a 24-port configuration, it provides 15.4 W to each port.
●
In 48-port configuration or any combination of ports where total PoE power does not exceed 370
watts, it provides 7.7 W to each port.
If the total system demands exceed this power limit, you can specify:
●
Port priorities to identify which ports should be ranked higher when allocating power.
●
Port disconnect precedence to specify the method of shutting off ports when not enough PoE power
is available.
NOTE
For a detailed discussion of these concepts, see the Power over Ethernet section in the ExtremeXOS
Concepts Guide .
External Power Supplies. The Summit X450e-48p switch can be powered by one, two, or three
external power modules through the redundant power input connector on the rear of the switch.
The EPS-C (External Power Supply Chassis) is shipped with the redundant power supply cable that
connects to the redundant input connector on the rear of the switch. The EPS-C chassis can hold from
one to three 600-Watt EPS-600LS external power module units.
