Summit X450, X450A, And X450E Series Switch Leds - Extreme Networks Summit X450a-24tDC Hardware Installation Manual

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 9 summarizes the PoE power behavior for the Summit X450e-48p switch based on
the number of power supply modules in use.
