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.

The PoE capability of the Summit X450e-48p switch varies depending on the number of external power modules in use. Table 11 summarizes the PoE power behavior for the Summit X450e-48p switch based on the number of power supply modules in use.
