The Juniper EX4550-32F-AFO is a high-performance, fixed-configuration 32-port 1GbE/10GbE SFP+ converged Ethernet switch designed for data-center, enterprise aggregation, and high-density network deployments.
Juniper's official ordering information identifies the EX4550-32F-AFO as a 32-port 1/10GbE SFP+ converged switch equipped with a 650W AC power supply, with port-side-to-PSU-side airflow. Optics are sold separately.
The AFO designation identifies the airflow direction. Juniper documentation explains that AFO means AIR OUT, with airflow moving from the port side toward the power-supply side (front-to-back when installed in the standard orientation).
The EX4550 platform also supports modular expansion options, Virtual Chassis capabilities, redundant power, and field-replaceable cooling components.
