Arista O-405 Wi-Fi 7 Outdoor Access Point

The Arista O-405 is a Wi-Fi 7 (802.11be) outdoor access point designed for campus exteriors, venue plazas, transit hubs, and other outdoor environments where the deployment calls for Wi-Fi 7 6GHz coverage alongside a practical 802.3at PoE+ power budget rather than the higher-wattage 802.3bt PoE++ required by the O-435. At 25W maximum power draw, the O-405 operates from any standard 802.3at PoE+ switch port, making it deployable from existing campus switching infrastructure without per-port PoE budget upgrades. Three concurrent 2×2:2 access radios on 2.4GHz, 5GHz, and 6GHz deliver a combined peak physical rate of 5.76 Gbps, with the 6GHz radio providing the low-interference outdoor channel that separates Wi-Fi 7 outdoor APs from the 5GHz-limited products they replace.

The uplink interface includes both a 5 GbE PoE+ RJ-45 port and a 10 GbE SFP+ fibre port, a combination that covers both copper campus distribution runs and fibre-fed pole or cabinet installations where a fibre home-run is the primary uplink medium. In mixed copper/fibre campus infrastructures this dual-interface design eliminates the need for separate AP SKUs for fibre-connected versus copper-connected mounting positions, reducing spare parts inventory. MTBF is rated at 1.4 million hours, which represents the O-405's core differentiator from the indoor C-400 model with the same radio specification: the 1.4M-hour MTBF reflects the environmental hardening of the chassis, connectors, and component selection required to sustain reliability across a -30°C to +65°C outdoor operating range. Memory is 2 GB RAM, 16 MB NOR flash, and 8 GB eMMC, hosting the full CloudVision CV-CUE stack locally with Automated Frequency Coordination (AFC) for outdoor 6GHz standard-power operation.
