The Juniper EX4550-32F is a high-performance, fixed-configuration Ethernet switch designed for enterprise and data center environments. It delivers rich Layer 2 and Layer 3 capabilities, low latency, and scalability for access, aggregation, and top-of-rack (ToR) deployments. Built on Juniper’s Virtual Chassis architecture, the EX4550 enables simplified management and scalability by interconnecting multiple switches into a single logical unit.
