1. High-Density Hybrid Architecture The hardware is designed for versatility, allowing you to mix long-distance fiber runs with local copper connections without needing additional converters.

Fiber Core: 24 × 100/1000 Mbps SFP ports for high-density optical distribution.

Copper Edge: 8 × 10/100/1000 Mbps RJ-45 ports for local servers, NVRs, or high-performance workstations.

10G Uplinks: 4 × 1/10 Gbps SFP+ slots. These are critical for eliminating bottlenecks when moving data to a Core switch or a 10GbE NAS.

2. Enterprise-Grade Throughput The internal "engine" of this switch is built for wire-speed performance, ensuring no packet loss even during peak surveillance or data transfers.

Switching Capacity: 144 Gbps (Total bandwidth the hardware can handle).

Packet Forwarding Rate: 107.136 Mpps (Millions of packets per second).

Large Packet Buffer: 16 Mbit buffer size helps manage traffic bursts, which is essential for stable high-resolution video streams.

MAC Table: Supports up to 32K addresses, making it suitable for large enterprise campuses with thousands of end-point devices.

3. Advanced L2+ Management & Routing While primarily a Layer 2 switch, the "Plus" designation refers to its ability to handle essential Layer 3 tasks locally.

Static Routing: Supports IPv4/IPv6 static routing. This allows the switch to route traffic between different VLANs internally, reducing the load on your main router.

VLAN Support: Up to 4094 VLAN IDs and 10 VLAN interfaces, allowing for deep network segmentation (e.g., separating guest Wi-Fi, VOIP, and IP Cameras).

Link Aggregation (LACP): Combines multiple ports into a single high-bandwidth logical link for redundancy and increased throughput.

4. Carrier-Class Resiliency Dahua has prioritized "Always-On" reliability for mission-critical deployments.

Dual Redundant Power Supplies: Features two built-in AC power modules. If one fails, the other takes over instantly with zero downtime.

ERPS (Ethernet Ring Protection Switching): Allows the creation of a fiber ring topology with recovery times under 50ms, ensuring the network remains functional even if a fiber cable is cut.

Environmental Hardening: Operates from –20 °C to +55 °C and features 4 kV lightning protection (common mode).

5. Management & Security Cloud Management: Fully integrated with DoLynk Care, allowing for remote configuration, real-time health alerts, and visual topology maps from a smartphone or browser.

Security Suite: Includes 802.1X port authentication, RADIUS, HTTPS, and Access Control Lists (ACL) to prevent unauthorized network entry.

QoS (Quality of Service): Uses SP/WRR queue scheduling to ensure that time-sensitive data (like Video or Voice) is never delayed by background data transfers.
