Ubiquiti UACC-ETH-SP-PANEL-24 Rack-Mount Surge Protection Panel
Overview
The Ubiquiti UACC-ETH-SP-PANEL-24 is a 1U rack-mounted Ethernet surge protection panel engineered to shield UniFi switching, gateway, and access point deployments from transient overvoltage, ESD, and EMP events. The panel accommodates 48 RJ45 connections in a compact 1U form factor, making it ideal for centralized protection at the rack level in enterprise, campus, and managed service provider environments. Built from SGCC steel with an operating temperature range of −40°C to +80°C, this accessory is designed for indoor cabinet installations where environmental stability is assured but electrical threats are not.
Key Features
- 48 Protected Ports: Each port passes full PoE++ power and data simultaneously—meaning you don't trade surge protection for power delivery. Critical if you're running high-draw cameras, access points, or PoE switches downstream.
- 20kA Surge Discharge per Port: Each port can handle 20,000 amps of transient current. This matters when lightning strikes nearby infrastructure or when inductive loads in your facility generate voltage spikes. Most consumer-grade protectors cap out at 5–10kA.
- Full PoE++ Passthrough: Supports up to 95W per port (802.3bt Class 4 PoE++), so high-powered cameras, multi-radio access points, and powered switches see no voltage drop or power compromise. If you're trying to protect a mixed deployment of low-draw IP phones and high-draw PTZ cameras on the same panel, this passthrough approach eliminates the need for separate protection circuits.
- Data Rates to 10 Gbps: The panel preserves link speeds up to 10 Gbps with <1 ns insertion delay. In practice: you're not bottlenecking your fiber uplinks or high-speed copper runs to your core switch. Relevant if you're building a converged enterprise network where 2.5G or 5G PoE infrastructure feeds into this protection layer.
- Response Time 100V/µs to 1kV/µs: This is the speed at which the surge protector reacts to rising voltage transients. Faster response = less energy reaches your equipment. This range (100V/µs upward) is industrial-grade protection, typical of carrier-class infrastructure panels rather than consumer surge strips.
- SGCC Steel Enclosure: Galvanized steel chassis resists corrosion and handles mechanical abuse in busy data centers. Not glamorous, but it prevents rust-induced contact degradation over years of deployment.
Integration & Compatibility
This panel integrates directly into Ubiquiti catalog deployments—UniFi switches, gateways, and access points all connect downstream via standard RJ45 cabling. Pair it with a PoE network switch on the upstream side and your protected ports branch out to field devices. Because it's a passive wired accessory with no management interface, there's no additional configuration or licensing overhead.
The UACC-ETH-SP-PANEL-24 (often searched as UACC ETH SP PANEL 24) is compatible with any standard Ethernet infrastructure and works equally well protecting UniFi devices or third-party IP cameras, VoIP endpoints, and environmental sensors—anything that uses RJ45 and tolerates PoE. Mount it in a standard 19-inch rack alongside your core switching gear.
Deployment Context
Use this panel in facilities where electrical transients are a known risk: buildings with heavy HVAC loads, sites near power distribution equipment, campuses with frequent thunderstorm activity, or industrial warehouses with high-inductive motor loads. If you're deploying a multi-camera surveillance system across outdoor perimeter and indoor access points, centralizing surge protection at the rack reduces the need for individual surge protectors at each device—simplifying maintenance and ensuring consistent protection across your entire UniFi footprint.
Frequently Asked Questions
Q: Does the UACC-ETH-SP-PANEL-24 require configuration or management?
A: No. This is a passive surge protection panel. You install it, wire upstream and downstream ports, and it operates without software, firmware updates, or dashboards. Once deployed, it works silently.
Q: Will the surge protection degrade over time?
A: Surge protection components wear with use, especially after repeated high-energy transient events. The UACC-ETH-SP-PANEL-24's specifications assume new devices. After sustained exposure to electrical stress, protection performance may degrade. No field-replaceable modules are mentioned in the specification, so the entire panel would require replacement after heavy surge events.
Q: Can I daisy-chain multiple UACC-ETH-SP-PANEL-24 units?
A: Yes. You can stack multiple panels in your rack and daisy-chain them via standard Ethernet cabling to protect more than 48 ports. Each panel operates independently with no inter-panel communication required.
Q: Is the UACC-ETH-SP-PANEL-24 suitable for outdoor use?
A: No. This is an indoor 1U rack-mount accessory. Operating temperature range is −40°C to +80°C, but it has no IP rating for water ingress or dust. Install it inside a secure cabinet or rack room only.
Q: Does this panel work with non-Ubiquiti network equipment?
A: Yes. Because it's a passive Ethernet surge protection panel with RJ45 ports, it works with any standard PoE infrastructure—Cisco, Juniper, Arista, or any other vendor's switches and devices. It's agnostic to the upstream or downstream hardware.

The UACC-ETH-SP-PANEL-24 fills a real gap in enterprise UniFi deployments—centralized surge protection without the management overhead or per-port cost of standalone protectors. The 20kA discharge capacity per port and sub-nanosecond insertion delay are hard specs you don't see on commodity surge strips, and the PoE++ passthrough means you're not trading power headroom for protection.
Technical Highlights:
- 20kA per Port + 100V/µs Response: Industrial-grade transient suppression. In practical terms: when a nearby lightning strike or inductive motor spike hits your facility, this panel clamps the overvoltage before it reaches your UniFi switch or cameras. Consumer-grade protectors (5–10kA) won't handle the energy density of a true electrical fault.
- Full PoE++ with <1ns Insertion Delay: The UACC-ETH-SP-PANEL-24 doesn't introduce measurable latency or power loss, even when delivering 95W per port to a high-draw access point or powered camera. This matters for converged deployments where you can't sacrifice either power budget or link speed.
- Passive, No Management: No firmware to patch, no dashboard to log into, no license keys. Deploy it once, and it protects autonomously for years—until a major surge event exhausts its internal protection components.
Deployment Considerations:
- Protection performance degrades after heavy transient events. The panel itself shows no visible damage, but internal MOV (metal-oxide varistor) elements accumulate stress. Monitor for repeated surge events in your facility and plan periodic replacement (multi-year intervals in most environments).
- This is passive protection only—it has no status LEDs, surge counters, or remote monitoring. You cannot tell from the management interface whether a transient event has degraded protection quality. If electrical threats are frequent (industrial sites, areas prone to lightning), add a separate monitoring circuit or schedule preventive panel replacement on a fixed cycle.
Positioning: The UACC-ETH-SP-PANEL-24 is the right choice for enterprise and campus deployments where UniFi infrastructure sits in a central rack and field devices (outdoor cameras, building-edge access points, perimeter gateways) connect back over potentially hazardous runs. It's overkill for small office deployments with short indoor cabling and low electrical threat exposure, but essential for multi-building campuses, industrial sites, and facilities with a history of electrical transients.
