power system. When a compatible external power supply is used with the Summit X440 series switch,
the internal and external power supplies are fully fault tolerant. If one power supply fails, the other
power supply will provide sufficient power to operate the switch.
Most Summit switches have fans that can change speeds depending upon operating conditions. See
