Juniper 920W AC Power Supply for EX4100 and EX3400, Front-to-Back

For EX4100 and EX3400 switches, the JPSU-920-AC-AFO provides 920W of AC power with front-to-back airflow. A higher-wattage supply in an access switch usually goes toward PoE. More supply wattage gives more power to share with phones, access points and cameras on the switch ports. A power cord is not included. Plan for a cord that suits your local outlet type. Match airflow with the fans in the switch. Front-to-back is the AFO direction, and every fan and supply in one chassis should move air the same way. Mixed directions work against the cooling design. The supply is offered New, Refurbished or Used. New and Refurbished units carry 1 year or 3 years of warranty. Used units carry 90 days. Send the quantity and switch model for pricing and lead time.
