A base-configuration EX9204 switch ships with two low-line (100–120 VAC) AC power
supplies or one high-line (200–240 VAC) AC power supply. An AC-powered,
redundant-configuration EX9204 switch ships with four low-line (100–120 VAC) or two
high-line (200–240 VAC) AC power supplies. See AC Power Supply in an EX9204 Switch.
A DC-powered, redundant-configuration EX9204 switch ships with two DC power supplies.
See DC Power Supply in an EX9204 Switch.
CAUTION: Do not mix AC and DC power supplies in the same chassis.
