Selection limits

Confirm exact hardware revision, regional model, adapter plug, firmware/controller support and required accessories before ordering. Published wireless PHY rates and maximum wired/VPN performance are conditional laboratory/standard limits, not guaranteed application throughput. PoE input powers this device; PoE output powers downstream equipment. Passive PoE is not automatically IEEE 802.3af/at/bt compatible; match voltage, polarity, pairs and available power budget.

Identifier scope

Documented model code. Regional ordering suffix and bundle are not invented and are confirmed separately.
