EX4200-48PX Juniper Switch

Refurbished EX4200-48PX Switch

The Juniper Networks® EX4200 line of Ethernet switches with Virtual Chassis technology combine the high availability (HA) and carrier-class reliability of modular systems with the economics and flexibility of stackable platforms, delivering a high-performance, scalable solution for data center, campus and branch office environments. Offering a full suite of Layer 2 and Layer 3 switching capabilities as part of the base software, the EX4200 satisfies a variety of high-performance applications, including branch, campus and data center access deployments as well as Gigabit Ethernet (GbE) aggregation deployments. A single 24-port or 48-port switch can be deployed initially; as requirements grow, Juniper Networks Virtual Chassis technology allows up to 10 EX4200 switches to be interconnected over a 128 gigabit-per-second (Gbps) backplane and managed as a single device, delivering a scalable, pay-as-you grow solution for expanding network environments. Flexible Gigabit Ethernet (GbE) and 10-Gigabit Ethernet (10GbE) uplink options enable high-speed connectivity to aggregation- or core-layer switches which connect multiple floors or buildings.

EX4200-48PX Switch: Product Features

• The EX4200 line of Ethernet switches deliver the same HA functionality and support many of the same failover capabilities as other Juniper chassis-based systems. 
• Each EX4200 switch is capable of functioning as a Route Engine.
• When two or more EX4200 switches are interconnected, they share a single control plane among all Virtual Chassis member switches. 
• When two EX4200 switches are interconnected, Junos OS automatically initiates an election process to assign a master (active) and backup (hot-standby) Route Engine.
• An integrated Layer 2 and Layer 3 Graceful Route Engine Switchover (GRES) feature maintains uninterrupted access to applications, services and IP communications in the unlikely event of a primary RE failure.
