Frequently Asked Questions

What is Juniper Virtual Chassis and how many EX4300 switches can be stacked?

Virtual Chassis allows up to 10 EX4300 switches to operate as a single logical switch with one management plane, one IP address, and a unified configuration — eliminating the complexity of managing individual switches while providing a 128 Gbps stacking fabric.

Does the EX4300-24T support PoE?

No — the EX4300-24T is a non-PoE model. For Power over Ethernet on all 24 ports, the EX4300-24P provides 370W PoE+ budget. Both models can be mixed within the same Virtual Chassis stack.

Can the EX4300-24T be managed by Juniper Mist?

Yes — the EX4300-24T supports Juniper Mist cloud management for AI-driven wired assurance, configuration automation, and anomaly detection when running a Mist-compatible Junos OS version.

The Juniper EX4300-24T delivers enterprise-grade Layer 3 switching with Virtual Chassis scalability and Junos OS consistency in a compact 1U form factor — providing the access layer foundation for campus networks that demand full routing capability, flexible uplinks, and unified cloud management through Juniper Mist.
