Juniper EX Series Ethernet Switches
Junos-powered switching from fanless access closets to a 13.2 Tbps modular core, unified by Mist AIOps.
Overview
The Juniper EX Series is HPE Juniper Networking's family of fixed and modular Ethernet switches that run Junos OS across every tier, from the access layer to the campus and data-center core. It is built for IT and network teams at federal agencies, K-12 and higher-ed campuses, healthcare systems, and enterprises that want one operating system and one AI-driven management plane from the wiring closet up.
The line spans eight platform families. EX2300, EX3400, EX4000, and EX4100 are fixed access switches in 8- to 48-port configurations with PoE, PoE+, or PoE++ variants. EX4400 and EX4650 step up to 100GbE uplinks for aggregation and small data-center roles. EX9200 and EX9250 are modular and fixed core platforms scaling to 13.2 Tbps. The newest member, EX4000, brings cloud-native, AI-native operations to the access edge with fanless and multigigabit models built for Wi-Fi 7 access points, while EX4100 and EX4400 extend EVPN-VXLAN fabric segmentation and MACsec AES-256 encryption all the way to the edge port.
Most EX models are managed through Juniper Mist with Wired Assurance, turning streaming telemetry into client-level service-level expectations that Marvis AI translates into plain-language troubleshooting. Virtual Chassis lets teams operate four to ten physical switches as a single logical device, and Gartner named Juniper a Leader in the 2025 Magic Quadrant for Enterprise Wired and Wireless LAN Infrastructure for the fifth consecutive year. As an authorized HPE Juniper Networking partner, Uniqcli sources TAA-compliant EX configurations for GPC, SAP, FAR, and GSA eBuy buyers alongside standard commercial purchasing.
Why Juniper EX Series Ethernet Switches
For federal, SLED, healthcare, and enterprise buyers, the EX Series lets an organization standardize every switching tier, access, aggregation, and core, on a single Junos operating system and, for most models, a single Mist cloud management plane. That consistency shrinks the training burden on stretched IT teams and shortens mean time to repair through Marvis AI's client-level telemetry. Virtual Chassis turns a stack of physical switches into one logical device to manage, and the ability to move from a fanless EX2300 closet switch to a 13.2 Tbps EX9214 core without changing operating systems protects both the skills investment and the automation scripts a team builds over time. As part of the HPE Juniper Networking portfolio, EX gives agencies and institutions a clear upgrade path while Uniqcli sources the right tier, TAA configuration, and contract vehicle for each site.
Eight platform tiers, one Junos foundation
From the fanless EX2300 to the modular EX9214 core chassis, every EX switch runs Junos OS, giving federal, SLED, and enterprise teams one CLI and one automation model from wiring closet to core.
EX4000: the AI-native access flagship
The newest EX line puts cloud-native, Wi-Fi 7-ready access switching within reach, with fanless 8- and 12-port models for occupied spaces and multigigabit PoE models scaling to 148 Mpps and 200 Gbps.
EX4400 pushes 3,600W of PoE++
48-port XP and MXP models deliver up to 3,600W of 802.3bt PoE++ across dual power supplies, MACsec AES-256 on every port, and 100GbE Virtual Chassis stacking for up to ten switches.
Gartner Leader for the fifth straight year
Gartner named Juniper a Leader in the 2025 Magic Quadrant for Enterprise Wired and Wireless LAN Infrastructure, positioned furthest in Completeness of Vision and highest in Ability to Execute for the fourth consecutive time.
EVPN-VXLAN reaches the access edge
EX4100 and EX4400 extend standards-based EVPN-VXLAN fabric and group-based-policy microsegmentation down to the wiring closet, not just the data center core.
Mist Wired Assurance and Marvis AI
Day 0 onboarding, Day 1 provisioning, and Day 2+ management run from the Mist cloud, with Marvis turning streaming telemetry into plain-language, client-level answers that cut mean time to repair.
EX9200/EX9250 scale to 13.2 Tbps
When a site outgrows fixed switching, the modular EX9204/9208/9214 chassis and fixed EX9250 platforms carry the same Junos operating model into the campus or data center core.
What it does
Anchors the access layer across the EX line
EX2300, EX3400, EX4000, and EX4100 cover fixed 8- to 48-port access switching in fanless, PoE, and multigigabit variants, feeding wired endpoints and Wi-Fi 6E/7 access points at branch, retail, K-12, and clinic edges.
Scales into campus aggregation and distribution
EX4400 and EX4650 step up to 100GbE uplinks, EVPN-VXLAN, and multi-Tbps throughput for wiring-closet aggregation and small data center top-of-rack roles.
Reaches modular core density with EX9200/EX9250
The EX9204/EX9208/EX9214 chassis and fixed EX9250 platforms deliver up to 13.2 Tbps for programmable campus and data center cores that outgrow fixed switches.
Delivers PoE, Fast PoE, and Perpetual PoE
PoE-capable models power phones, cameras, sensors, and APs; Perpetual PoE keeps endpoints powered through a switch reboot and Fast PoE restores power during boot before the switch is fully operational.
Streams telemetry for Mist AIOps
EX switches send switch-health and service-level data to the Mist cloud, generating pre- and post-connection wired SLEs that Marvis AI turns into plain-language root-cause answers.
Stacks as one logical device with Virtual Chassis
Virtual Chassis combines multiple EX switches (four on EX2300/EX4650, six on EX4000/EX4100, ten on EX3400/EX4400) into a single managed unit with one IP address and one control plane.
Segments traffic with EVPN-VXLAN and MACsec
EX4100 and EX4400 extend EVPN-VXLAN fabric and group-based-policy microsegmentation to the access edge, with MACsec AES-256 encryption on copper and fiber ports for data-in-motion protection.
Enables Zero Trust wired access
Pairing EX switches with Juniper Access Assurance brings identity-based, Zero Trust network access control down to the wiring closet without a separate NAC appliance.

How to buy Juniper EX Series Ethernet Switches
EX Series switches are sold as HPE SKUs through the HPE Juniper Networking storefront, with Mist cloud subscriptions licensed separately by term and tier. As an authorized HPE Juniper Networking partner, Uniqcli quotes the switch, the subscription, and the support attach as one package so budgets do not get split across separate POs.
Hardware plus Mist subscription
EX switches ship as standalone hardware; Wired Assurance and other Mist cloud services are licensed by subscription term (1, 3, 5, or longer years) per switch. We size the subscription tier to the AIOps features you actually need.
GPC, SAP, FAR, and GSA eBuy contract vehicles
Federal buyers can route EX Series purchases via GPC direct, SAP, FAR-based purchase orders, or GSA eBuy where currently listed. Tell us your preferred vehicle and required TAA configuration and we confirm eligible SKUs before quoting.
GPC and standard PO purchasing
SLED, healthcare, and commercial buyers can transact by Government Purchase Card for smaller orders or standard purchase order for larger deployments, with net terms available on qualifying accounts.
Refresh and trade-in credit
Retiring Cisco Catalyst, Aruba, or older Juniper EX gear can offset new EX4000, EX4100, or EX4400 purchases. We handle the trade-in valuation and logistics as part of the quote.
Bundled with access points and support
Most deployments pair EX switches with Mist or Aruba access points and an HPE support tier. Bundling hardware, subscriptions, and support into one quote through /bom keeps a multi-site rollout on a single line-item budget.

How much PoE budget do EX switches deliver?
It varies by tier. EX2300 tops out near 740W per switch. EX4000 and EX4100 24/48-port multigig models reach roughly 1,440W to 1,620W with dual power supplies. EX4400 48-port XP/MXP models deliver up to 3,600W of 802.3bt PoE++ across dual supplies, enough for dense Wi-Fi 6E/7 AP and camera deployments. We size the PoE budget to your per-site device count during quoting.
How are EX switches managed?
All EX switches run Junos OS. EX4000, EX4100, and EX4400 are built for cloud management through Juniper Mist with Wired Assurance handling Day 0 through Day 2+ operations, and Marvis AI surfacing client-level insight. Virtual Chassis lets you operate multiple physical switches as one logical device regardless of tier.
What is Virtual Chassis and how many switches can it stack?
Virtual Chassis combines multiple physical EX switches into a single managed device with one IP address and one configuration. The switch limit differs by model: four switches on EX2300 and EX4650, six on EX4000 and EX4100, and up to ten on EX3400 and EX4400. We help plan stack size against your port and uplink needs.
Where do I get a quote for EX Series switches?
Request pricing directly through /quote with your port counts, PoE requirements, and preferred contract vehicle, or add EX Series line items to a multi-product deal on /bom. We confirm current SKU availability and lead times before sending a formal quote.
What support and warranty come with EX switches?
EX Series hardware is backed by HPE and Juniper support programs, and Mist-managed models require an active cloud subscription for Wired Assurance and Marvis AIOps features. We quote the right support tier and subscription term alongside the hardware so nothing lapses after Day 1.
