Data Sheet EX4300 LINE OF ETHERNET SWITCHES Product Description Product Overview The EX4300 line of Ethernet switches delivers the performance, flexibility, and scale required for both campus and data center Gigabit Ethernet (GbE) access switch environments. Whether deployed in a Virtual Chassis configuration or as a satellite device in a Juniper Networks Junos Fusion fabric architecture, the EX4300 delivers the operational simplicity and higher logical scale that businesses demand. Combining compact, pay-as-yougrow economics and low power and cooling with the performance, availability, and port densities of chassis-based platforms, the EX4300 enables businesses to deploy with speed and agility to increase revenue and improve productivity. 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 formfactor 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 corelayer switches which connect multiple floors or buildings. All EX4300 switches include high availability (HA) features such as redundant, hotswappable 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. Additionally, a multigigabit model, the EX4300-48MP, supports IEEE 802.3bzcompliant 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps speeds on access ports. This enables 802.11ac Wave 2 access points, which require higher bandwidth, to connect to the switch. The EX4300 multigigabit switch also supports up to 95 watts of power on any of the access ports, enabling PoE++ devices requiring more than 30 watts to connect to and draw power from the switch. Finally, the EX4300 multigigabit switch enables higher levels of Media Access Control Security (MACsec) AES256 encryption on all access and uplink ports, protecting customer traffic from unauthorized access.

EX4300 Line of Ethernet Switches MACsec EX4300 switches support IEEE 802.1AE MACsec, providing support for link-layer data confidentiality, data integrity, and data origin authentication. The MACsec feature enables the EX4300 to support 88 Gbps of near line-rate hardware-based traffic encryption on all GbE and 10GbE ports, including the base unit and optional uplink modules. The multigigabit EX4300 model supports the MACsec AES 256 standard for encrypting traffic on all access and uplink ports. Defined by IEEE 802.1AE, MACsec provides secure, encrypted communication at the link layer that...
