Description

This 320 W AC power supply is a hot-swappable, field-replaceable unit for Juniper EX3200 and EX4200 Series Ethernet switches. It offers an autosensing 100-240 V AC input, installs from the rear panel without powering the switch down, and provides redundancy in EX4200 switches through the internal redundant power supply slot. The 320 W rating distinguishes it from the higher-capacity 600 W and 930 W AC models in the same family.
