Summit X250E Series Switch Leds - Extreme Networks Summit X150 Series Hardware Installation Manual

•
In a 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 one of the following:
•
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 EPS-600LS External Power Module provides optional redundant power for the Summit X250e-48p
switch.
Through the redundant power input connector on the rear panel, the switch can be powered by one,
two, or three external power modules installed in the EPS-C External Power Supply Chassis.
The PoE capability of the Summit X250e-48p varies depending on the number of external power
modules in use. The following table summarizes the PoE power behavior for the Summit X250e-48p
switch based on the number of power supply modules in use.
