Description

The EX4000-48P is a cloud-managed access switch in the EX4000 series, built for enterprise branch offices, remote sites and campus networks. It powers IP phones, cameras, IoT devices and Wi-Fi access points from a single 1U unit, and is managed through Juniper Mist Wired Assurance with Marvis Virtual Network Assistant.

It provides 48 10/100/1000BASE-T ports, each delivering 802.3at PoE+ at up to 30 W, from a 740 W total PoE budget. Four SFP/SFP+ ports handle uplinks and Virtual Chassis connections: 2 x 1G/10G SFP/SFP+ uplinks and 2 x 10G SFP+ Virtual Chassis ports that can also be configured as network ports. Switching capacity is 88 Gbps unidirectional, non-blocking, with Layer 2 and Layer 3 throughput of 130 Mpps. Up to six EX4000 switches can be joined in a Virtual Chassis.

The switch runs Junos OS with Flex Standard tier software. Flex Advanced and Flex Premium licences unlock additional features and subscription tiers add Mist Wired Assurance. SFP and SFP+ optics are fitted to the uplink ports as required.
