DS-3E0326P-E-M – 24-Port Fast Ethernet Unmanaged PoE Switch with Gigabit Combo Uplink (300m Ultra-Long-Range PoE, 230W Budget, 6kV Surge Protection, VIP Port Prioritization)

Product Overview

The DS-3E0326P-E-M is a high-density 24-port Fast Ethernet unmanaged Power over Ethernet (PoE) network switch purpose-built for commercial, enterprise, and multi-camera IP video surveillance deployments. Equipped with 24 × 10/100 Mbps PoE downlink ports alongside 2 × Gigabit Combo uplink ports (10/100/1000 Mbps RJ-45 or 1000 Mbps SFP fiber slot), the switch delivers flexible, high-bandwidth core connectivity back to central Network Video Recorders (NVRs), server infrastructure, or core network backbones without uplink bottlenecks.

Engineered specifically for demanding surveillance topography, the unit features an extended transmission mode capable of delivering PoE power and network data up to 300 meters (984 ft) over standard Cat5e/Cat6 cabling on designated ports (1–24 at 10 Mbps), eliminating the need for midspan extenders or remote power supplies at far perimeters. Built with an internal industrial power supply delivering a robust 230W aggregate PoE power budget (up to 30W per port compliant with IEEE 802.3af/at), the switch incorporates hardware-level VIP Port Prioritization (Ports 1–8) to guarantee uninterrupted video transmission for mission-critical cameras during peak network congestion. Housed in a durable 19-inch 1U rackmount all-metal chassis, it features industrial-grade 6kV lightning surge protection on all PoE ports to protect system equipment from electrical transients.

Key System Features & Functionality

• High-Density 24-Port PoE Downlinks: Features 24 auto-sensing 10/100 Mbps RJ-45 ports supporting IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards.

• Dual Gigabit Combo Uplinks: 2 Gigabit combo ports (RJ-45 Ethernet / SFP fiber module slots) provide reliable high-speed aggregation to NVRs and core distribution switches.

• 300-Meter Ultra-Long-Range PoE: Hardware DIP-switch toggle extends data and power transmission distance from standard 100m up to 300 meters (984 ft) at 10 Mbps.

• Robust 230W Total PoE Power Budget: Delivers up to 30W on individual ports to power PTZ domes, multi-sensor cameras, and active deterrence units with an aggregate 230W capacity.

• VIP Port Priority Streaming (Ports 1–8): High-priority data queue buffers ensure key evidentiary video channels maintain stable streaming even under heavy bandwidth saturation.

• Intelligent PoE Power Management: Automatically detects connected PD device classes and prevents power overloads with smart power allocation and auto-cutoff protection.

• Industrial 6kV Lightning Surge Protection: Integrated surge suppression on all Ethernet ports safeguards connected endpoints against voltage spikes and lightning strikes.

• Standard 19" 1U Rackmount Chassis: Sturdy galvanized steel chassis includes rackmount brackets for seamless installation into standard server and telecom racks.
