Juniper Networks EX4100, 24-port 10/100/1000BASE-T switch, 4x10GbE uplinks, 4x25GbE stacking/uplink ports, MACsec AES256, redundant fans | EX4100-24T

The Juniper Networks EX4100-24T is a 24-port non-PoE Gigabit Ethernet switch with 10GbE uplinks and 25GbE stacking/uplink ports, suited to organizations building secure, centrally managed wired access networks.

Recommended For

• Campus and branch network teams connecting up to 24 wired devices in a wiring closet, with 10GbE uplinks for connecting the access switch to faster aggregation or core layers.
• IT teams managing access switches across multiple sites that want Mist cloud onboarding, configuration, and telemetry, while retaining CLI or J-Web management options.
• Enterprise network teams building segmented campus or branch networks that need EVPN-VXLAN support at the access layer and MACsec AES-256 switch-to-switch encryption.
• Organizations expanding in stages that want to interconnect up to 10 EX4100 switches as a Virtual Chassis managed as a single device.

Real-World Use Scenarios

• In a small office or campus wiring closet, IT staff can connect up to 24 gigabit Ethernet devices—such as computers and printers—and use the faster uplinks to connect the switch to the wider network. The result is a straightforward wired access layer, with endpoints needing their own power because this model does not provide PoE.
• For a branch with Juniper Mist management, network staff can onboard the switch to the cloud and apply shared configurations across sites. This can make routine provisioning and monitoring more consistent, provided the organization has the required Wired Assurance subscription and network connectivity.
• When a campus network needs separate access policies for groups such as staff, guest, or IoT devices, administrators can use supported group-based policies and EVPN-VXLAN designs to segment traffic. The practical outcome is more controlled communication between endpoint groups, when these features are configured as part of the network design.
• In a growing branch or campus closet, several EX4100 switches can be joined in a Virtual Chassis and managed as one device. This can simplify switch administration as the number of access ports grows, rather than requiring each switch to be handled separately.
• Where switch-to-switch links carry traffic across areas with added security requirements, administrators can enable MACsec on supported links. Traffic is encrypted while it travels over those links, but MACsec does not encrypt traffic within the switch itself.
