The AC power supply in EX4300 switches is a hot-insertable and hot-removable field-replaceable unit
(FRU): You can install it without powering off the switch or disrupting the switching function.
All the EX4300 switches that are powered by AC power supplies, except EX4300-24T-S, EX4300-24P-S,
EX4300-32F-S, EX4300-48T-S, EX4300-48P-S, and EX4300-48MP-S switches are shipped with one AC
power supply installed in the rear panel of the switches. EX4300-24T-S, EX4300-24P-S, EX4300-32F-S,
EX4300-48T-S, EX4300-48P-S, and EX4300-48MP-S switches are not shipped with power supplies; you
must order the power supplies separately.

715 W, and 1100 W AC power supplies. EX4300-48MP and EX4300-48MP-S switches support
