EX4100-24MP: 10GBASE-T Copper Access Switch with PoE++
The Juniper EX4100-24MP is the only model in the EX4100 line with native 10GBASE-T on its multigigabit access ports, which makes it the right answer for wired endpoints that need real 10-gigabit copper, not just multigig. Eight ports support 100M, 1, 2.5, 5, and 10GbE over Category 6a cabling, alongside 16 PoE++ gigabit ports. This is the access switch for closets where high-bandwidth wired workstations, NAS clusters, video-editing bays, or industrial control endpoints share space with standard 1GbE devices. As part of the
Juniper EX4100 Series, the 24MP combines that copper-10GbE access role with the same Mist-cloud management, EVPN-VXLAN fabric extension, and PoE++ power delivery as the larger 48-port models.

What makes the 24MP unique in the EX4100 family:
- Native 10GBASE-T on Copper: The only EX4100 SKU that supports 10GbE over Category 6a copper on access ports. No SFP+ modules, no fiber dependency for high-bandwidth wired endpoints.
- PoE++ on 24 Ports: 1440W total PoE budget across the access ports with 90W per-port capability for any device that needs it: APs, cameras, building IoT.
- Higher Switching Capacity Than the 48-Port Models: 236 Gbps unidirectional and 351 Mpps forwarding. Faster than the 48-port EX4100 models because of the higher-speed access ports.
- Right-Sized for Smaller Closets: 24 ports is the right footprint for branch IDFs, broadcast and edit rooms, lab spaces, and small floor closets where 48 ports is overkill.
- Same Uplinks as Larger Models: 4 x 1/10GbE SFP+ plus 4 x 10/25GbE SFP28 stacking/uplink ports. Full feature parity with the 48-port EX4100s for distribution-layer connectivity.
- Virtual Chassis Mixing: Combine 24MP and 48-port EX4100 models in the same Virtual Chassis stack. Manage as a single logical device.
PoE++ on the Same Ports That Run 10GBASE-T
Where the 24MP separates from competing 24-port access switches is the combination of 10GBASE-T copper access AND 90W PoE++ on the same physical ports. Most multigigabit access switches force a choice: high-bandwidth wired endpoints OR high-power PoE++. This SKU delivers both — every access port runs Category 6a copper at up to 10GbE while also supporting up to 90W of Type 4 PoE++ from the same RJ-45.
- PoE++ on 10GbE Copper Ports: Run a Wi-Fi 6E AP, a 4K PTZ camera, or a high-draw industrial controller from the same port that delivers 10GbE data. No fiber, no media converters.
- 1440W Dual-PSU Budget: Sufficient for 24 fully-loaded access ports at typical mixed-class draw, with headroom for higher-class devices.
- Fast PoE Recovery: Powered devices come back within seconds of a power event. Critical for production environments where downtime carries direct cost.
- 802.3bt LLDP Negotiation: Devices auto-request the precise wattage they need, freeing budget for the high-draw endpoints in the closet.

10GBASE-T-Sized Switching Architecture
The 24MP switching architecture is sized for its multigigabit access role. 236 Gbps unidirectional capacity and 351 Mpps forwarding are intentionally higher than the 48-port EX4100 models because each of the 8 access ports can drive 10GbE concurrently, and the switch must absorb that aggregate load without contention.
- 236 Gbps Unidirectional Capacity: 472 Gbps bidirectional with non-blocking architecture. Sized for 8 x 10GbE access ports + 16 x 1GbE + uplinks all active concurrently.
- 351 Mpps Forwarding Rate: Highest forwarding rate in the EX4100 line. Handles small-packet, latency-sensitive workloads like media production traffic and industrial-control packets.
- Flexible 25GbE Stacking: 4 x SFP28 ports configure for Virtual Chassis at 25GbE per link or repurpose as Ethernet uplinks for tighter distribution-layer aggregation.
- 10GbE SFP+ Fixed Uplinks: 4 dedicated SFP+ ports preserve always-on northbound bandwidth, even when SFP28 ports are used for stacking.
Hardware for Branch and IDF Deployments
Designed for environments where the 24MP is the only switch in the room: branch offices, remote IDFs, broadcast studios, lab buildings. Dual hot-swappable 920W PSUs deliver redundancy without a second chassis, and the 1U footprint fits cramped wall-mount closets.
- 1U Branch-Friendly Footprint: 10.06 lb (4.57 kg) chassis with front-accessible ports. Fits standard wall-mount and 2-post-rack branch enclosures.
- Dual 920W AC PSUs: Hot-swappable for service without dropping the closet. Either PSU alone handles 740W PoE budget, workable redundancy for non-critical sites.
- 60.9 CFM Cooling: Lowest airflow demand among PoE++ EX4100 models. Quieter operation for branch environments where the switch shares the room with people.
- Field-Replaceable Fan Modules: Two fans, redundant. Single-fan failure does not require unit replacement.
- 0 to 45 C Operating Range: Non-AC tolerated. Qualifies for retrofit IDFs and remote sites with HVAC failures.
Security and Fabric Integration
Security and fabric features are consistent across the EX4100 line — the same MACsec, EVPN-VXLAN microsegmentation, and Junos-driven access control as the larger Juniper enterprise switching portfolio.
- MACsec AES-256: Line-rate switch-to-switch encryption on supported ports, securing traffic between access and distribution layers.
- EVPN-VXLAN to Access: Extend campus fabric segmentation end-to-end with group-based policies and consistent traffic isolation per device class.
- 802.1X Access Control: Port-based authentication, MAC authentication, RADIUS-driven dynamic VLAN assignment, and Voice VLAN support.
- Control-Plane Protection: CoPP, DHCP snooping, dynamic ARP inspection, IP source guard, and DDoS protection mitigate Layer 2/3 attacks.
Where the 24MP Fits
Three deployment patterns where the 24MP outperforms larger-port EX4100s and competing multigig access switches.
Branch and Remote-Site IDF
A single 24MP per branch handles 8 high-bandwidth wired workstations at 10GbE, 16 lower-bandwidth desktops or phones, and stacks via 25GbE if a second is needed. Mist cloud automation lets a central team manage hundreds of branches without on-site IT.
Broadcast, Post-Production, and Media Editing
10GbE copper to edit bays, NAS, render nodes, and 4K cameras with PoE budget for camera-mounted lighting. Tight, low-latency switching for collaborative timeline work.
Industrial Control Rooms and Labs
Engineering workstations on 10GbE, ruggedized cameras and sensors via PoE++, and isolated control-system VLANs on one switch. EVPN-VXLAN microsegmentation keeps OT separate from corporate IT.
Where the 24MP Earns Its Slot
Verticals where wired 10GBASE-T endpoints justify this SKU over a denser 1GbE platform.
- Media and Post-Production: Edit suites, color grading rooms, render farms. 10GbE copper to workstations and shared storage eliminates the SFP+/fiber-to-the-desk cost without losing bandwidth.
- Engineering and CAD Workplaces: High-end workstations doing CAD, simulation, or 3D rendering. Large file loads that saturate gigabit links.
- Branch Banking and Trading Floors: Single-switch branch deployments where a few traders or analysts need 10GbE and the rest of the office runs standard PoE+ phones and APs.
- Lab and Research Facilities: Instrument-heavy spaces with mixed bandwidth needs. High-throughput data acquisition systems alongside standard wired desktops.
Regulatory Compliance
The Juniper EX4100 line complies with major environmental and safety standards across all SKUs, enabling global deployments and sustainable lifecycle management.
- RoHS: Restriction of Hazardous Substances compliance.
- REACH: EU regulatory compliance for chemical-substance registration and authorization.
- WEEE: Waste Electrical and Electronic Equipment Directive for responsible recycling and end-of-life handling.

Get the 24MP in Stock
For closets where wired 10GBASE-T copper endpoints share space with standard PoE devices — branch IDFs, edit suites, engineering offices, lab and industrial control rooms — the
EX4100-24MP is the right Juniper platform. BrightStar Systems supplies tested, refurbished 24MP units with documented condition reports and US-stock availability. Our team can confirm cabling category requirements for 10GBASE-T on your runs and help size PoE budget across mixed device classes.
Q: Does the EX4100-24MP really support 10GBASE-T over copper on access ports?
A: Yes. Eight of the access ports support 100M / 1 / 2.5 / 5 / 10GbE over copper cabling, making the 24MP the only EX4100 model with native 10GBASE-T on the RJ-45 access ports. The other 16 access ports are PoE++ gigabit.
Q: What cabling do I need to actually get 10GBASE-T on the 24MP?
A: Category 6a cabling is the practical requirement for 10GBASE-T over 100-meter runs. Category 6 will run 10GbE at shorter distances (typically up to 55 meters) in well-isolated conditions. Pre-existing Category 5e runs will not deliver 10GbE reliably.
Q: Can the same port deliver 10GbE data AND 90W PoE++ simultaneously?
A: Yes. The 24MP’s access ports combine multigigabit Ethernet (up to 10GbE on the 8 multigig ports) with up to 90W of IEEE 802.3bt Type 4 PoE++ on the same RJ-45 — useful for power-hungry endpoints that also need 10GbE data, like high-throughput cameras or industrial controllers.
Q: When should I choose the 24MP over the larger 48MP?
A: Pick the 24MP when you need real 10GBASE-T copper on access ports (the 48MP tops out at 2.5GbE on its multigig ports) or when 24 ports is the right size for the closet — branch IDFs, edit suites, lab spaces, or small floor closets where 48 ports would be wasted.
Q: How does Virtual Chassis work between the 24MP and the 48-port EX4100 models?
A: All EX4100 SKUs share the same 25GbE SFP28 stacking interconnect. You can mix a 24MP and a 48MP (or 48T / 48P) in a single Virtual Chassis stack of up to 10 members, managing them as one logical device.
