Switching (QFX for Data Center, EX for Campus)

In the data center, QFX with Apstra delivers intent‑based EVPN‑VXLAN fabrics, closed‑loop assurance, and scale from 400/800GbE toward 1.6 TbE designs.
Across the campus, EX switches with Mist AI bring AI‑ops, SLE visibility, and open APIs for secure segmentation and streamlined operations.

Modernize your switching—from core to edge.

Data Center (QFX + Apstra)

  • EVPN‑VXLAN fabric design for scalable leaf‑spine architectures.
  • Closed‑loop assurance with intent validation and continuous compliance.
  • High‑speed readiness: 400/800 GbE and a path to 1.6 TbE designs.
  • Multivendor operations: Apstra abstracts vendors to standardize DC ops.

Campus (EX + Mist)

  • AI‑ops & SLEs: Experience‑centric insights and faster remediation.
  • Segmentation: Role‑/policy‑based access, 802.1X/MACsec options.
  • API‑first & open: Automate with REST/NETCONF/Webhooks and templates.
  • Consistent wired edge: Unified policies with Mist‑managed access.

EX4100 F

Compact, cost-effective, AI-native solution designed for branch deployments, offering fanless and PoE+ options across multiple port configurations. Supports cloud-based management via Juniper Wired Assurance, and includes advanced features like EVPN-VXLAN, GBP microsegmentation, and flow-based telemetry.

In short: EX4100‑F → quietest, most affordable cloud option for small zones; EX4100 → standard access with mGig+PoE++ option for modern APs/IoT.

Compact, scalable 10GbE switch ideal for campus distribution, featuring advanced technologies like EVPN-VXLAN, MACsec AES-256, and microsegmentation. Supports cloud-based management via Juniper Wired Assurance and Mist AI, enabling real-time telemetry and simplified operations.

EX4650
EX4650 (48× 10/25 GbE + 8× 40/100 GbE)

Compact, high-performance 10GbE/25GbE/100GbE switch designed for midsize to large campus 
distribution networks, delivering rich telemetry for AI-driven automation  and service assurance. 
Cloud-ready and ZTP-enabled, it integrates with Juniper Wired Assurance for streamlined onboarding, 
configuration, and real-time operational visibility.

Recommendation based on typical SME size

10–30 employees (one floor/small office) Access: EX4100‑F‑12P (fanless PoE+) or EX4100‑24P (PoE+). Reason: quiet, affordable cloud management; can be expanded later via VC.

30–120 employees (multiple zones, modern APs) Access: EX4100‑24MP/48MP (mGig + PoE++). Core/Agg: 1× EX4400‑48P/48MP (collapsed core) or 2× EX4400 (VC). Reason: PoE++/mGig for Wi-Fi 6E/7, EVPN-VXLAN-ready, high PoE budgets.

>120 employees / campus core required Access: EX4100-MP or EX4400-(M)XP depending on PoE/mGig requirements. Core/Dist: 2× EX4650 (25/100 GbE uplinks; VC). Reason: clean separation of access/distribution, scalable uplinks.

PoE/AP sizing (short & important)

Wi-Fi 6E/7 APs may require PoE++ (802.3bt, up to 90 W/port) when all radios/features are active (e.g., AP45/45E; some reduced modes run on 802.3at). Therefore, plan for PoE reserves. EX4100-MP and EX4400 deliver PoE++ and high total budgets (up to 3600 W per switch).

Why "Mist Wired Assurance" for SMEs?

Cloud onboarding (ZTP), templates, dynamic port profiles (colorless ports), wired SLEs, Marvis Insights/Actions → faster commissioning, fewer tickets, better visibility from client to port.

Quick Pick (at a glance) 

Quiet/small & cloud-managed: EX4100-F.

Standard access today, mGig/PoE++ optional: EX4100.

High-power access/collapsed core: EX4400 (up to 3600 W PoE, Wi-Fi 7-ready).

Distribution/small core (25/100 GbE): EX4650.
