The Juniper EX4200 is an enterprise 1U stackable switch that pioneered Juniper Virtual Chassis technology, enabling up to 10 switches to interconnect over a dedicated 128 Gbps backplane bus. Available in 24 and 48-port Gigabit configurations with full PoE support and modular uplink slots (4x 1GbE SFP or 2x 10GbE SFP+), the EX4200 combines dual hot-swappable internal power supplies and fan trays with carrier-grade Junos stability. In secondary hardware channels, the EX4200 remains a benchmark legacy model for lab environments and spare part inventories.
