Two high-performance stacking ports with associated LEDs
●
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
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 is capable of 370 W of PoE power:
15.4 W supplied to each port for a 24-port configuration and 7.7 W supplied to each port for a 48-port
configuration or any combination of ports where total PoE power does not exceed 370 watts. 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
A full discussion of these concepts is in the ExtremeXOS 12.0 Concepts Guide, Power over Ethernet section.
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.
