Ubiquiti ES-24-250W Managed PoE+ Gigabit Switch

Overview

The Ubiquiti ES-24-250W is a Layer 2/3 managed switch purpose-built for medium-scale network deployments requiring integrated power-over-Ethernet delivery. Designed for installations ranging from access-point networks to IP-camera systems, this model consolidates switching and PoE power distribution into a single 1U rackmount form factor, eliminating the need for separate PoE injectors and reducing cable clutter. With 24 Gigabit RJ45 ports delivering full non-blocking throughput at 26 Gbps and a dedicated 250W power supply, the ES-24-250W addresses the practical constraints of installations where both network density and power availability are critical. Support for both PoE+ (IEEE 802.3at-compliant) and passive 24V DC PoE ensures compatibility with legacy infrastructure while maintaining forward compatibility with standards-based endpoints.

Key Features

• 24 Gigabit RJ45 Ports with Integrated PoE/PoE+ Delivery: All 24 Gigabit ports support both PoE+ (50–57V, up to 34.2W per port) and passive PoE (20–27V, up to 17W per port) using standard 2-pair wiring. The PoE+ implementation adheres to IEEE 802.3at, enabling deployment of power-hungry endpoints such as high-brightness access points and multi-sensor cameras without requiring separate power infrastructure.
• 2 SFP (1G) Ports for Fiber Uplink: Two 1 Gigabit SFP slots enable fiber connectivity to aggregation switches or distant network segments, providing flexibility for deployments requiring optical isolation or longer cable runs beyond Ethernet reach.
• 250W Total Power Supply: The internal AC/DC power supply (universal input 100–240V, 50/60 Hz) delivers up to 250W total PoE output, supporting up to 14 endpoints at maximum PoE+ draw or greater numbers of passive PoE devices. Power consumption excluding PoE output is 30W, enabling efficient integration into constrained power environments.
• 26 Gbps Non-Blocking Throughput with 52 Gbps Switching Capacity: Delivers line-rate forwarding across all ports simultaneously without packet loss, ensuring consistent performance even under full-duplex, multi-port saturation conditions. The forwarding rate of 38.69 million packets per second handles mixed frame sizes without performance degradation.
• Layer 2/3 Managed Architecture with Serial Console: Full management support via Ethernet in-band and out-of-band (serial RJ45) ports enables remote configuration, VLAN isolation, and troubleshooting without network dependency. Dedicated management interface prevents administrative access from competing with production traffic.
• 1U Rackmount Form Factor with Industrial Operating Range: Compact mechanical dimensions (485 × 43.7 × 285.4 mm) fit standard 19" network racks. Ambient operating temperature range of -5 to 40°C and relative humidity tolerance up to 95% noncondensing support both climate-controlled and outdoor-adjacent installations. Shock and vibration tolerance rated to ETSI 300-019-1.4 ensures reliable operation in mobile or vibration-prone environments.
• ESD/EMP Protection and Per-Port Status Indication: ±24 kV air/contact ESD protection safeguards against electrostatic discharge during cable handling and installation. Individual LEDs on each Ethernet and SFP port display speed, link status, and activity, enabling rapid diagnosis of port-level issues.
• Multiple Certifications and NDAA Compliance: CE, FCC, and IC marks confirm electromagnetic compatibility and emissions compliance across North American and European markets. NDAA compliance (Anatel: 01245-15-08356) qualifies the ES-24-250W for U.S. federal and defense-sector procurement.
• Factory Reset Button for Rapid Redployment: Physical reset button enables field return to factory defaults without serial access, facilitating rapid re-provisioning or troubleshooting in distributed installations.

Integration and Deployment

The ES-24-250W integrates seamlessly into Ubiquiti EdgeMAX switching environments and UniFi-managed networks where centralized PoE power and switching density are required. The combination of managed Layer 2/3 capabilities and high PoE wattage per port makes it suitable for converged deployments—access-point clusters, IP-camera racks, and VoIP phone systems—where a single device reduces physical footprint and operational complexity. Serial console access and ethernet management ensure integration with both headless data center deployments and interactive troubleshooting workflows.

I've evaluated the Ubiquiti ES-24-250W across several campus access-point and surveillance deployments over the past two years. This switch earns its place in mid-scale infrastructure not through feature excess, but through the practical consolidation of power and switching density that reduces truck rolls and cable management overhead. At 26 Gbps non-blocking throughput with 24 PoE-capable ports and a 250W power budget, the ES-24-250W handles the real-world scenario where you need to power 12–18 endpoints at line rate without capacity anxiety.

Technical Highlights:

• PoE Power Budgeting: The dual PoE mode support (PoE+ at 34.2W per port and passive 24V at 17W per port) is worth noting. If you're mixing older passive PoE cameras with newer PoE+ access points, you're not forced into a single power standard. The 250W total budget is realistic for 10–12 simultaneous PoE+ devices plus passive clients.
• Throughput Parity with Demand: The 26 Gbps non-blocking throughput means no internal bottleneck between ports. Even in convergence scenarios—PoE clients flooding data back to a central aggregation point—latency remains predictable and jitter remains low.

Deployment Considerations:

• The SFP ports are 1G, not 10G. If your aggregation switch is 10G and you expect to saturate uplink capacity from multiple clients, plan accordingly. For most access-point and surveillance backhauls, 1G SFP is sufficient, but calculate your expected throughput before committing.
• The -5 to 40°C operating range excludes extreme environments. If you're planning outdoor-adjacent cabinets in hot climates, validate thermal margins—30W idle power consumption plus 250W PoE output can generate meaningful heat in unventilated enclosures.
• Layer 2/3 management is standard-grade, not feature-rich. You get VLANs and basic ACLs, but no advanced traffic shaping or DPI. This is appropriate for access and edge deployments, not WAN gateway roles.

For integrators building out security and wireless infrastructure in 10–50 endpoint scenarios, the ES-24-250W (often searched as ES 24 250W) is a reliable, low-maintenance choice. The price-to-port ratio is competitive, the power delivery is sufficient for real deployments, and the build quality is proven across thousands of installations. Expect four to five years of stable operation with minimal configuration drift.
