Ubiquiti ES-48-500W Edgeswitch 48,500W,70gbps,2 SFP(+) ports

Ubiquiti ES-48-500W Managed Power Over Ethernet Plus Gigabit Switch

Overview

The Ubiquiti ES-48-500W is a Layer 2/3 managed switch designed for medium to large IP camera deployments, VoIP infrastructure, and access point networks requiring consolidated power distribution. With 48 Gigabit RJ45 ports delivering PoE+ on all ports, a dedicated 500W internal power supply, and non-blocking 70 Gbps throughput, the ES-48-500W consolidates network switching and power delivery into a single 1U rackmount unit. This model supports both industry-standard PoE+ (50–57V) and passive PoE (20–27V) on separate pin pairs, enabling flexible deployment across mixed endpoint types.

Key Features

• 48 Gigabit PoE+ Ports: All 48 RJ45 ports deliver up to 34.2W per port via PoE+, totaling 500W of available PoE budget for simultaneous endpoint power and data delivery.
• Dual-Mode PoE Support: PoE+ injection on pins 1, 2+ and 3, 6- (standard); passive PoE on alternate pins 4, 5+ and 7, 8-, enabling support for legacy and modern PoE endpoints without additional midspans.
• 70 Gbps Non-Blocking Throughput: Full-duplex switching capacity of 140 Gbps and forwarding rate of 104.16 Mpps eliminate bottlenecks in high-density deployments.
• Uplink Flexibility: Two 10G SFP+ ports and two 1G SFP ports provide fiber connectivity for backbone aggregation, redundancy, or long-distance runs without copper limitations.
• Layer 2/3 Management: Managed switching with CLI and web GUI interfaces, serial RJ45 console port, and SNMP support for integration into centralized monitoring systems.
• 1U Rackmount Form Factor: Compact 485 x 43.7 x 374.6 mm dimensions fit standard 19-inch racks; weighs 6.1 kg for stable mounting in distributed cabinets or head-end equipment rooms.
• Low Standby Power Draw: Only 64W max power consumption (excluding PoE output) reduces operational cost and thermal load in climate-controlled facilities.
• Robust Environmental Rating: Operates across -5 to 40°C ambient temperature and up to 95% non-condensing humidity; meets ETSI300-019-1.4 shock and vibration standards for outdoor or semi-outdoor enclosures.
• ESD/EMP Protection: ±24 kV air/contact ESD protection safeguards against electrostatic discharge common in field installations.
• NDAA Compliance: Meets U.S. Department of Defense National Defense Authorization Act requirements for federal and critical infrastructure projects.
• Universal AC Input: 100–240V AC, 50/60 Hz internal AC/DC power supply eliminates regional power adapter conflicts in multi-site deployments.
• Status Indication: Per-port PoE, speed, link, and activity LEDs; SFP/SFP+ port LEDs; factory reset button for field troubleshooting and initialization.

Integration & Compatibility

The ES-48-500W integrates seamlessly into Ubiquiti UniFi ecosystems via Layer 2/3 switching, supporting VLAN segmentation for multi-tenant or multi-purpose networks. Serial console and Ethernet in/out-of-band management enable remote configuration and monitoring. The switch's passive PoE capability supports legacy Ubiquiti airMAX and EdgeMAX devices that predate 802.3at standardization, while PoE+ ports power modern WiFi 6 access points, IP cameras, and door controllers without auxiliary power injection. Fiber SFP+ uplinks integrate with Ubiquiti EdgeMAX routing platforms or third-party optical networks for backbone redundancy.

Certifications include CE, FCC, and IC (North American and European regulatory approval). The model is often searched as ES 48 500W or ES-48-500W interchangeably.

Jerry Tildsen

I have evaluated the ES-48-500W during the planning phase of a 200-camera deployment across a distributed facility. The primary appeal is the 500W PoE budget and non-blocking 70 Gbps switching—no bandwidth contention when all 48 ports are active, which is critical for sustained surveillance and uptime SLAs.

Technical Highlights:

• PoE Density: 500W total budget across 48 ports allows roughly 10W average per port, sufficient for most IP cameras (5–12W typical) and access points (10–20W). High-power PTZ cameras or dual-radio APs require per-port planning.
• Throughput Headroom: 70 Gbps non-blocking throughput and 104.16 Mpps forwarding ensure zero packet loss during simultaneous data and PoE delivery across all ports; no queue buildup in converged voice/video networks.

Deployment Considerations:

• Dual PoE modes (standard and passive) are convenient for mixed-legacy environments, but require careful pin labeling and endpoint validation to avoid cross-wiring.
• SFP+ uplinks integrate well with fiber backbone runs; test optical modules for compatibility (Ubiquiti OptiLink or third-party SFP+ transceivers) before field deployment.

The 1U form factor and 64W idle draw make it ideal for compact head-end rooms or outdoor cabinets with AC power and climate control. The combination of managed switching, robust PoE delivery, and dual-mode pin support delivers reliable consolidation for medium-scale security and network infrastructure projects.
