The **WS-RNW3U** is a professional-grade wall-mount network rack cabinet (typically 3U in height). While it is primarily a mechanical enclosure, its "electronic parts" refer to the integrated power distribution, cooling systems, and the active components it is designed to house. --- ### 1. Key Internal Components & Features The WS-RNW3U is designed for low-profile, vertical mounting of electronic equipment. Below are the primary technical elements: | Component | Description | Function | | :--- | :--- | :--- | | **PDU (Power Distribution Unit)** | Internal multi-outlet power strip (often 4-6 ports). | Provides centralized power to all housed devices. | | **Cooling Fans** | Integrated 120mm AC or DC brushless fans. | Active thermal management to prevent hardware overheating. | | **Grounding System** | Copper grounding lugs and studs. | Protects electronics from static discharge and electrical surges. | | **Mounting Rails** | Adjustable 19-inch standard rack rails. | Ensures secure physical connection for servers and switches. | --- ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Rack Units** | 3U (Vertical or Horizontal placement) | | **Material** | SPCC Cold Rolled Steel | | **Input Voltage (Fans/PDU)** | 110V - 240V AC | | **Static Loading Capacity** | Approximately 30kg - 60kg (depending on wall anchors) | | **Cable Management** | Top and bottom brush-panel entry points | --- ### 3. Electronic Equipment Compatibility The WS-RNW3U is specifically engineered to protect and power the following types of electronic hardware: * **Networking Gear:** Managed switches (Cisco, Ubiquiti), Patch Panels, and Routers. * **Security Systems:** NVRs (Network Video Recorders) and DVRs for CCTV. * **Audio/Visual:** Amplifiers and distribution headers. * **Power Backup:** Small-form-factor UPS (Uninterruptible Power Supplies). --- ### 4. Thermal & Electrical Safety To ensure the longevity of the electronics inside, the WS-RNW3U utilizes specific design choices: 1. **Perforated Ventilation:** Side or front venting to allow the fans to pull cool air across the internal circuitry. 2. **Electrostatic Discharge (ESD) Protection:** The powder-coat finish is typically designed to be non-conductive, while internal points are left bare for grounding.
