Common questions
Does the DC version reverse airflow?
No. This configuration uses front-to-back airflow. The EX4400-24X-DC-AFI provides back-to-front airflow.
Can the uplink configuration be expanded?
Yes. An optional module adds either four 10GbE interfaces or four 25GbE interfaces.
Does DC power affect the Virtual Chassis limit?
This model supports up to 10 Virtual Chassis members through its QSFP28 connections.
