Does it need a license?

The base software covers Layer 2 switching and basic Layer 3 (static routing, RIP and OSPFv2). BGP, IS-IS, MPLS and the IPv6 routing protocols need Juniper's Advanced Feature License (AFL), which is bought separately.

What is the PoE budget?

Its 930W power supply delivers PoE+ to all 48 ports at up to 18.6W each, which is what makes it an option for dense phone or camera deployments.

Is it managed L2 or L3?

Both. It runs Layer 2 switching and Layer 3 routing on Junos, so it can act as an access switch or a small routed core.

Yes, last support 30 June 2024; consider the EX4300 or EX4400.

What is Virtual Chassis?

Juniper's stacking technology. Up to ten EX4200 units connect together and are managed as a single logical switch with one configuration and one management address.

Product overview

The Juniper EX4200-48PX is a 48-port full-PoE+ access switch with Juniper's Virtual Chassis technology, which lets up to ten units act as a single logical switch managed as one, a genuinely useful feature for wiring closets. It is a capable Layer 2 and Layer 3 platform running Junos. It is also end of life, so this is a value buy for labs, spares and cost-sensitive deployments rather than a switch to standardize a new network on.

48x Gigabit PoE+ ports, 930W supply for full power budget
136 Gbps capacity, 32000 MAC, 4096 VLANs supported
Layer 2/3 with 10G uplinks, Jumbo Frames, QoS features
Virtual Chassis stacks up to 10 units for scalability
0-45°C operation, 1U rack-mount 8.61 kg design
IEEE 802.3 compliant, wired Gigabit Ethernet connectivity
