AC Power Supply Configurations | 46
An EX9214 switch is configurable with two or four AC power supplies. The power supplies connect to
the midplane, which distributes the different output voltages produced by the power supplies to the
switch components, depending on their voltage requirements. Each power supply is cooled by its own
internal cooling system.
CAUTION: EX9214 switches use either AC or DC power supplies. Do not mix AC and
DC power supplies in a switch. The first type of power supply detected by the switch
when it is initially powered on determines the type of power supply the switch will
operate with. All installed power supplies of the other type are disabled by the switch. If
