An EX9214 switch is congurable with two or four AC power supplies. The power supplies connect to
the midplane, which distributes the dierent 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 rst type of power supply detected by the switch
when it is inially 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
