Description

The Juniper EX4000-12MP is a compact, fanless 12-port Multigigabit access switch from the EX4000 series. It is built for enterprise branch offices, remote offices and campus edge deployments, particularly where Wi-Fi 6E and Wi-Fi 7 access points, IP phones, cameras and IoT devices need multigigabit PoE++ power. The fanless design suits quiet, space-constrained and non-rack environments.

The switch provides 4x 100M/1G/2.5GBase-T Multigigabit ports and 8x 10/100/1000Base-T ports, and all 12 access ports support IEEE 802.3bt PoE++ at up to 60W per port from a 240W total PoE budget. Two 1G/10G SFP/SFP+ uplink ports and two 10G SFP+ Virtual Chassis ports (configurable as network ports) handle upstream connectivity. Packet switching is non-blocking at 58 Gbps unidirectional, with 86 Mpps L2/L3 throughput.

This model ships with the Flex Standard software tier and is managed from the cloud through Juniper Mist Wired Assurance. OSPF and BGP routing, along with other advanced features, require a Flex Advanced or Flex Premium licence. Up to six EX4000 switches can be joined in a Virtual Chassis and managed as one logical device.
