Hardware Interfaces & Power Specifications

Wired Interfaces

1. 1 × 100/1000/2500BASE-T Multigigabit (mGig) RJ45 uplink port, compatible with IEEE 802.3bz NBASE-T, transmits data and receives PoE power over a single Cat5e/Cat6 cable
2. RJ45 RS‑232 local console port for device configuration, firmware upgrade and field troubleshooting
3. USB 2.0 auxiliary port for local diagnostics and lightweight edge IoT application hosting
4. Multi-color LED status indicator for boot state, WLC association, runtime operation and hardware fault alert
5. Physical reset button for one-touch factory configuration recovery
6. Kensington lock slot for physical anti-theft protection

Power Supply Compatibility

• Primary: IEEE 802.3at PoE+ (30W power budget), required for full 4×4 MIMO dual-radio performance and USB port activation
• Limited operation via IEEE 802.3af PoE: When powered by af PoE, radios downgrade to 2×2 MIMO, Ethernet uplink drops to 1Gbps, and USB port is disabled to reduce thermal load
• Compatible PoE injectors: AIR-PWRINJ5 (802.3af), AIR-PWRINJ6 (802.3at)Cisco.

Supported Deployment Operation Modes

1. CAPWAP Lightweight Controller Mode: Centralized unified wireless policy management via Catalyst 9800 physical/virtual WLCs, global RF resource scheduling, seamless inter-AP client roaming, centralized security enforcement and network analytics.
2. EWC Embedded Wireless Controller Standalone Mode: Runs lightweight virtual wireless controller locally on the AP for independent branch, classroom or small office networks without dedicated WLC hardware (model suffix EWC denotes preloaded EWC firmware)Cisco.
3. Auxiliary operational modes: Monitor Mode, Sniffer Mode for RF spectrum capture and wireless traffic analysis.

Enterprise-Grade Wireless Security Suite
