Juniper EX4100 Series

IT teams that need compact PoE access with room for stronger wireless links can use the Juniper EX4100 Series to keep branch and campus edge networks under one managed layer. It supports controlled wired and wireless access, with Mist AI visibility, secure policy control and Virtual Chassis management helping reduce day-to-day switch sprawl.

It suits access closets, clinic wings, office floors and depot rooms where powered endpoints, cameras and APs need reliable connectivity without overbuilding the closet. Mixed port options help match local demand, keep wireless responsive and support growth without adding management overhead.

Juniper EX4100 Quick Specs & Key Features

Multi-gigabit PoE access: Selected ports support higher-speed copper and powered Ethernet for dense Wi-Fi zones and connected devices, so small closets can backhaul modern APs without overbuilding the access layer.
Cloud-managed operations: Mist AI visibility and cloud-ready management centralise monitoring and policy changes across branch and campus edge, so teams can reduce hands-on administration and speed up deployment.
Virtual Chassis scaling: Multiple access switches can operate as one managed system, so enterprises can expand port capacity and simplify day-to-day control without adding separate management overhead.

Secure access policy: Junos-based access control and enterprise security features help enforce segmentation and device access rules at the edge, so branches and campus closets maintain consistent policy with lower risk.
Power delivery flexibility: PoE and non-PoE options across the range let IT match power to endpoint needs, so sites avoid unnecessary power hardware and keep closet design efficient.
Edge deployment fit: Compact access-switch designs for branch and campus networks support mixed wired and wireless endpoints, so hotels, clinics, offices and depots can scale access cleanly as demand changes.

Juniper EX4100 Deployment Scenarios and Industries

Hotels and Hospitality

Hotel teams need reliable access for guest Wi-Fi, cameras, phones and room systems across floors and back-of-house areas. The EX4100 Series supports smaller closets through to higher-density floor deployments with PoE, secure access, cloud management and Virtual Chassis scaling where more ports or wireless headroom are needed.

Healthcare

Clinical and admin areas need secure wired and wireless access for carts, phones, patient systems and APs, often from limited comms rooms. The EX4100 Series fits compact clinics through to larger ward closets with PoE, consistent access policy and options for higher-capacity AP connections where traffic is busiest.

Finance

Branches and back-office floors need dependable access for staff devices, voice, cameras and secure Wi-Fi while keeping closets simple to run. The EX4100 Series supports small sites and denser office areas with PoE and non-PoE options, secure access controls and cloud-managed visibility.

Professional Services

Tenant offices need a practical access layer for desks, meeting rooms, AV and Wi-Fi without overbuilding the network. The EX4100 Series covers small suites through larger floors, giving teams PoE where needed, multi-gigabit support for busy collaboration spaces and simpler multi-switch operation.

Logistics

Depots and warehouse offices need stable connectivity for scanners, phones, cameras, APs and fixed terminals from one managed access layer. The EX4100 Series supports powered and non-powered edge rooms, helping teams scale port counts, keep wireless coverage in place and reduce closet complexity.
