Juniper EX 4300 Network Switch - 48 port 10/100/1000BASE-T - 550 W DC PSU - Back-to-front airflow (EX4300-48TDC-AFI)

The Juniper Networks EX4300 line of Ethernet switches 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. Both 1GbE access and multigigabit switch options are available.

Offering a full suite of Layer 2 and Layer 3 switching capabilities, the EX4300 enables a variety of deployments, including campus, branch, and data center access. A single 24-port or 48-port EX4300 switch can be deployed initially. As requirements grow, Juniper's Virtual Chassis technology allows any combination of up to 10 EX4300 and/or EX4600 switches to be seamlessly interconnected and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments. A pair of 32-port EX4300 fiber switches can also be deployed as a consolidated aggregation or small core switch. Additionally, the EX4300 can integrate with the Juniper Networks QFX5100 line of 10GbE and 40GbE data center access switches in a single stack or Virtual Chassis configuration, enabling nondisruptive 10GbE server upgrades and simplified management of a mixed access environment.

The EX4300 switches can be interconnected over multiple 40GbE quad small form factor pluggable plus (QSFP+) transceiver ports to form a 320 gigabit per second (Gbps) backplane. A flexible uplink module that supports both 1GbE and 10GbE options is also available, enabling high-speed connectivity to aggregation- or core layer switches which connect multiple floors or buildings.

All EX4300 switches include 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 models offer standards-based 802.3at PoE+ for delivering up to 30 watts on all ports to support high-density IP telephony and 802.11n wireless access point deployments.
