Juniper Networks ships EX4100 switches with one power supply installed in the rear panel. You can
install up to two power supplies in an EX4100 switch. The power supply slots are numbered 0 and 1,
and each slot has a power icon next to it. The power supplies support front-to-back airflow or back-to-
front airflow. They are fully redundant, load-sharing, hot-removable and hot-insertable field-replaceable
units (FRUs). Hot-removable and hot-insertable mean that when the second power supply is installed
and running, you can remove and replace the power supplies without powering off the switch or
disrupting switch functions. This topic describes the AC power supplies that EX4100 switches support.
