The Juniper Networks EX4300 line of Ethernet switch with Virtual Chassis technology combines the 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, the EX4300 satisfies a variety of high-performance applications, including branch, campus, and data center access deployments as well as Gigabit Ethernet (GbE) access deployments. As requirements grow, Juniper Networks Virtual Chassis technology allows up to 10 EX4300 switches to be interconnected and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments. The EX4300 switch can be interconnected over multiple 40GbE quad small form-factor pluggable plus (QSFP+) transceiver ports to form a 320 gigabits per second (Gbps) backplane.
EX4300 switch includes high availability (HA) features such as redundant, hot-swappable internal power supplies and field-replaceable fans to ensure maximum uptime. In addition, Power over Ethernet (PoE)-enabled EX4300 switch offers standardsbased 802.3at PoE+ for delivering up to 30 watts on all ports for supporting high-density IP telephony and 802.11n wireless access point deployments.
The EX4300 line of Ethernet switches delivers the same HA functionality and supports many of the same failover capabilities as other Juniper chassis-based systems. EX4300 switch is capable of functioning as a Routing Engine. when two or more EX4300 switches are interconnected, a single control plane is shared among all Virtual Chassis member switches. when two EX4300 switches are interconnected, Junos OS automatically initiates an election process to assign a master (active) and backup (hot-standby) Routing Engine. An integrated Layer 2 and Layer 3 GRES feature maintains uninterrupted access to applications, services, and IP communications in the unlikely event of a primary RE failure.
The EX4300 line of Ethernet switches provides the high levels of availability for the most demanding converged data, voice, and video environments, delivering the reliable platform for unifying enterprise communications. By providing 15.4 watts of Class 3 802.3af PoE on all ports to power voice over IP (VoIP) telephones, closed-circuit security cameras, wireless access points, and other IP-enabled devices, the EX4300 delivers a future-proofed solution for converging disparate networks onto a single IP infrastructure. The EX4300 switch also supports standards-based 802.3at PoE+, which delivers up to 30 watts per port for powering networked devices like multiple radio IEEE 802.11n wireless access points and video phones that may require more power than available with IEEE 802.3af.
Simplified management and operations
When employing Virtual Chassis technology, the EX4300 dramatically simplifies network management. Up to 10 interconnected EX4300 switches can be managed as a single device. The EX4300 also includes port profiles that allow network administrators to automatically configure ports with security, QoS, and other parameters based on the type of device connected to the port.
