## Long description

The Juniper EX4000-12P is a managed L2/L3 Gigabit Ethernet access switch with 12 RJ-45 ports and integrated Power over Ethernet (PoE). Designed for access-layer deployments in branch and remote offices, this 1U rack-mountable switch supports cloud-managed workflows via Juniper Mist Wired Assurance and provides features for multigigabit devices, virtual chassis aggregation, and predictable PoE delivery. The switch implements Junos OS and delivers a switching capacity suited to small-to-medium access infrastructures while offering high-availability capabilities when used in Virtual Chassis configurations.
Advantages
The EX4000-12P combines cloud-native management and AI-driven telemetry to simplify provisioning, monitoring, and troubleshooting of access networks. Built-in PoE support and multigigabit port options accommodate modern endpoints such as Wi‑Fi 6/6E/7 access points and IP cameras, while Virtual Chassis capability enables multiple switches to operate as a single logical device for simplified management and redundancy. Junos OS delivers a consistent software platform and proven high-availability features such as graceful Routing Engine switchover and nonstop forwarding.
Suitable for
Branch and remote office access layer switching
Small-to-medium enterprise access networks connecting Wi‑Fi 6/7 access points and IP cameras
Environments requiring cloud-managed switches with telemetry and AI-driven insights
Deployments that benefit from Virtual Chassis aggregation and simplified single-pane management
Key specifications
Ports: 12 x Gigabit RJ-45 access ports (10/100/1000)
PoE: Support for IEEE 802.3af/at, 802.3bt PoE standards and multigigabit PoE options
Uplinks: Fixed SFP/SFP+ uplink ports supporting 1GbE/10GbE
Switching capacity: 52 Gbit/s
MAC address table size: 32,000 entries
Layer support: Managed L2 and L3 features, ACL and QoS support
Networking standards: Comprehensive IEEE 802.1 and 802.3 family support (VLAN, STP/RSTP/MSTP, LACP, LLDP, 802.1x)
Form factor: 1U rack-mountable, compact grey chassis
Weight: approximately 3.12 kg
How to use
Rack-mount the EX4000-12P in a standard 19-inch equipment rack using the supplied brackets. Connect access devices to the RJ-45 ports and link upstream to the network using the SFP/SFP+ uplink ports as required. Onboard the switch to Juniper Mist Wired Assurance for zero-touch provisioning, or access the device locally through the RJ-45 console port for initial configuration via Junos OS. Configure VLANs, QoS, PoE profiles, and L2/L3 policies according to your network design. For redundancy and simplified management, interconnect up to six EX4000 units to form a Virtual Chassis using the designated SFP+ ports.
Usage recommendations
Monitor PoE budget and per-port power settings when connecting high-power devices and enable Fast or Perpetual PoE modes if continuous power to endpoints is required during switch reboot. Use Juniper Mist Wired Assurance to collect telemetry and leverage Marvis for troubleshooting to reduce mean time to repair and streamline ongoing management.
