• EX4100-24MP and EX4100-48MP use the 920W AC AFO (Airflow Out) PSU (Power Supply Unit)
FRUs.
• EX4100-48T uses the 150W AC AFO PSU FRU.
• EX4100-48T-DC usess the 150W DC AFO PSU.
• EX4100-48T-AFI uses the 150W AC AFI (Airflow In) PSU FRU.
• EX4100-24T uses the 150W AC AFO PSU FRU.
• EX4100-24T-DC uses the 150W DC AFO PSU FRU.
• EX4100-F-48P uses the built-in 850W AC power supply.
• EX4100-F-48T uses the built-in 90W AC power supply.
• EX4100-F-24P uses the built-in 450W AC power supply.
• EX4100-F-24T uses the built-in 65W AC power.
FRU power supplies of EX4100 switch models are fully redundant, load-sharing, hot-removable and hot-
insertable when the second power supply is installed and running. You can remove and replace them
without powering off the switch or disrupting switch functions. The EX4100 switches ship with one
power supply preinstalled in the rear panel of the chassis. Each power supply includes its own internal
cooling system.
CAUTION: Avoid mixing:
• AC and DC power supplies in the same chassis.
• Power supplies with different airflow directions in the same chassis.
• Fan modules with different airflow directions in the same chassis.
• Power supplies and fan modules with different airflow directions in the same chassis.
If you install power supplies or fan modules with different airflow directions, Junos OS
raises an alarm.
