The PoE capability of the Summit X450e-48p switch varies depending on the number of external power
modules in use. Table 28 summarizes the PoE power behavior for the Summit X450e-48p switch based
on the number of power supply modules in use.
For more information, see “EPS-600LS External Power Module” on page 143.
