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. When deployed in a Virtual Chassis configuration, the EX4300 delivers the operational simplicity and higher logical scale that businesses demand. Combining compact, pay-as-you-grow 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.
Additionally, a multigigabit model, the EX4300-48MP, supports IEEE 802.3bz-compliant 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.
The EX4300 multigigabit switch also enables higher levels of Media Access Control Security (MACsec) AES256 encryption on all access and uplink ports, protecting customer traffic from unauthorized access. The EX4300-48MP includes four dedicated 40GbE QSFP+ transceiver ports that can be used as Virtual Chassis ports to create a 320 Gbps backplane.
