connector allows you to connect the switch to the EPS-160, EPS-500, or EPS-150DC external power

supply. When a compatible external power supply is used with the Summit X250e series switch, the

internal and external power supplies are fully fault tolerant and load-sharing. If one power supply fails,

the other power supply will provide sucient power to operate the switch.
