Juniper Networks 650W DC Power Supply for EX4550 & QFX3500 PSU Side Airflow Exhaust

The DC power supply in EX4550 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 EX4550 switches that are powered by DC power supplies, except the EX4550-32F-S switches are shipped with one DC power supply pre-installed in the rear panel of the switches. EX4550-32F-S switches are not shipped with pre-installed power supplies; you must order them separately.
