The Juniper EX4200-48 is a high-performance, stackable 48-Port Gigabit Ethernet switch designed for enterprise data centers, campus networks, and high-density branch environments. Part of Junipers EX Series, this switch delivers flexible Layer 2 and Layer 3 switching, robust security, and simplified network management with Virtual Chassis technology, enabling multiple switches to operate as a single, logical unit for easy scalability and high availability.

With 48 Gigabit Ethernet ports and optional 10-Gigabit uplinks, the EX4200-48 supports high-speed connectivity for servers, workstations, wireless access points, and IP surveillance devices. It provides wire-speed performance, low latency, and enterprise-class reliability, suitable for voice, video, and mission-critical applications.

The switch supports advanced network features including VLAN, QoS, IGMP snooping, Link Aggregation, Layer 3 static routing, OSPF, RIP, VRRP, and policy-based traffic management. Enterprise security is ensured with 802.1X authentication, DHCP snooping, dynamic ARP inspection, MAC limiting, and access control lists (ACLs), protecting sensitive business networks from unauthorized access.

Junipers Virtual Chassis technology allows up to 10 EX4200 switches to be interconnected, simplifying management while providing high availability and redundancy. Management options include CLI, SNMP, Junos Space Network Management, and Web-based GUI, giving administrators complete control over configuration, monitoring, and automation.

With redundant power supply options, front-to-back airflow, and energy-efficient design, the EX4200-48 is optimized for reliable 247 operation while minimizing operating costs.
