The **W2AP-535-R2/UL** is a high-performance, enterprise-grade wireless access point, commonly associated with the **Aruba (HPE) 530 Series** architecture. These devices are designed to handle dense environments using the Wi-Fi 6 (802.11ax) standard. Below is a breakdown of its core electronic components and technical specifications. --- ### 1. Core Hardware Specifications The internal electronics are centered around high-efficiency MU-MIMO (Multi-User, Multiple Input, Multiple Output) radios and a powerful processing engine. | Component | Description | | :--- | :--- | | **Processor (CPU)** | Quad-core Cortex A53 (typically 2.2GHz) for high-speed packet processing. | | **Radio 1 (5 GHz)** | 4x4 MIMO, Wi-Fi 6 (802.11ax), supporting speeds up to 2.4 Gbps. | | **Radio 2 (2.4 GHz)** | 4x4 MIMO, Wi-Fi 6 (802.11ax), supporting speeds up to 1,147 Mbps. | | **Bluetooth/Zigbee** | Integrated BLE (Bluetooth 5.0) and 802.15.4 radio for IoT and location services. | | **Memory** | High-density RAM (often 1GB-2GB) to manage large client tables. | --- ### 2. Connectivity and Power Interfaces The electronic layout includes several physical ports to facilitate high-speed backhaul and power delivery. * **Ethernet Ports:** * **E0:** 100/1000/2500/5000 Base-T (RJ-45) auto-sensing link speed (Smart Rate). * **E1:** 10/100/1000 Base-T (RJ-45). * **USB Interface:** A USB 2.0 host port (Type A connector) for cellular modems or IoT dongles. * **Power Input:** * **PoE:** 802.3at (PoE+) or 802.3bt (Class 5). * **DC Jack:** 12V DC nominal (± 5%) for local power supply. --- ### 3. Electronic Protection and Certifications The "UL" suffix in the model name indicates specific regulatory compliance, ensuring the electronics meet safety standards for installation in "plenum" spaces (air-handling spaces). * **UL 2043 Rating:** This ensures the electronic housing is "Plenum Rated," meaning it produces low smoke and is heat-resistant. * **TPM (Trusted Platform Module):** Integrated security chip for secure storage of digital certificates and encryption keys. * **Intelligent Power Monitoring (IPM):** An electronic firmware feature that allows the device to disable certain hardware features (like the USB port or second Ethernet) if the power supply (PoE) is insufficient. --- ### 4. RF (Radio Frequency) Path The electronic signal chain includes: 1. **Filters:** Advanced band-pass filters to minimize interference from cellular networks (Advanced Cellular Coexistence - ACC). 2. **Antenna Arrays:** Internal omnidirectional antennas optimized for horizontal ceiling mounting. 3. **Amplifiers:** Low-noise amplifiers (LNA) for receiving weak signals and Power Amplifiers (PA) for transmitting across the coverage area.
