Juniper-Networks EX4300-48T

Description

The Juniper Networks EX4300-48T is part of the Juniper EX4300 Series, a family of high-performance, fixed-configuration Ethernet switches designed for enterprise campus and data-center access environments.

The switch provides 48 Gigabit Ethernet RJ45 ports, supporting 10/100/1000 Mbps connectivity for workstations, servers, printers, IP phones, wireless access points, cameras, and other network devices. The 48T model is a non-PoE configuration, making it appropriate for deployments where connected equipment has independent power or where PoE is not required.

The EX4300-48T includes modular uplink capability, allowing compatible uplink modules to be installed for higher-speed connections to aggregation and core network infrastructure. This provides flexibility as network bandwidth requirements increase.

The switch runs Juniper Junos OS, providing integrated Layer 2 and Layer 3 switching and routing capabilities. It supports VLANs, VLAN tagging, STP/RSTP/MSTP, Link Aggregation (LACP), static routing, OSPF, BGP, VRF, IPv6, multicast, and advanced QoS.

A key feature of the EX4300 platform is Virtual Chassis technology, which allows multiple compatible switches to be interconnected and managed as a single logical device. This simplifies configuration and management while providing increased scalability and resiliency.

The EX4300 also supports advanced enterprise security capabilities, including 802.1X access control, MAC authentication, DHCP snooping, Dynamic ARP Inspection, IP Source Guard, firewall filters, and network segmentation.

The switch is housed in a compact 1U rack-mount chassis, making it suitable for enterprise network cabinets, server rooms, and campus distribution/access locations.
