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.
