	Power Source	2.4-GHz radio	5-GHz radio		6-GHz radio		Link speed		USB	Max PoE power consumption
	802.3bt (Class 6) (UPOE)	4×4	4×4(LB) + 4×4(HB)		4×4		2x 10G		Y (9W)	47W
	802.3at (PoE+) (Quad Radio mode)	2×2	2×2 (LB) + 2×2 (HB)		2×2		2x 2.5 G		N	25.5W
	802.3at (POE+) (Tri Radio Mode)	2×2	4×4 (FB)		2×2		2x 1G		N	25.5W
	802.3af (PoE)	–	–		–		1x 1G		N	13.95W
	Note: Actual power consumption may vary depending on access point usage. It is recommended that you ensure that Link Layer Discovery Protocol (LLDP)/Cisco Discovery Protocol is enabled to allow proper power negotiation. Note: FB is Full Band, LB is Lower UNII Bands (UNII 1 and 2) and HB is Higher UNII Bands (UNII 2E and 3). Note: Above power draw table starting with IOS-XE version 17.15.3.
Power consumption	Power Source			Idle				Typical
	802.3bt (UPOE)			20.7W ±2W				25.7W ±4W
	802.3at (PoE+)			14.5W ±2W				16.8W ±4W
	Note: Actual power consumption may vary depending on AP usage. Typical power consumption assumes AP is passing traffic^* during typical business hours, and is idle during off-business hours. Business hours are assumed to be 11 hours a day, 6 days a week. ^* Test Conditions: 802.3bt: The 6 GHz, 5 GHz high-band and 5 GHz low-band all operating at 160 MHz (4×4) passing 1 Gbps per band of download traffic and the 2.4 GHz band operating at 20 MHz (4×4) passing 150 Mbps of download traffic; USB disabled; 2x 10G Ethernet Ports; Ambient temperature 25˚C (77°F). 802.3at: The 6 GHz and the 5 GHz bands both operating at 160 MHz (2×2) passing 1 Gbps per band of download traffic and the 2.4 GHz band operating at 20 MHz (2×2) passing 150 Mbps of download traffic; USB disabled; 1x 10G Ethernet Port; Ambient temperature 25˚C (77°F).
Environmental	● Nonoperating (storage) temperature: -22° to 158°F (-30° to 70°C) ● Nonoperating (storage) altitude test: 25˚C (77°F) at 15,000 ft (4570 m) ● Operating temperature: 32° to 122°F (0° to 50°C) ● Operating humidity: 10% to 90% (noncondensing) ● Operating altitude test: 40˚C (104°F) at 9843 ft (3000 m) Note: When the ambient operating temperature exceeds 40˚C (104˚F), the access point will shift from 4×4 to 2×2 on the 2.4-GHz, 5-GHz and 6-GHz radio(s); however, the USB interface will remain enabled.
Available transmit power settings	2.4 GHz ● 23 dBm (200 mW) ● -4 dBm (0.39 mW)			5 GHz ● 23 dBm (200 mW) ● -4 dBm (0.39 mW)				6 GHz ● 23 dBm (200 mW) ● -4 dBm (0.39 mW) Note: In countries where use of the 6-GHz band is not allowed or there is no current software support, the 6-GHz radio will be disabled. The radio may be enabled with future software, once the product is certified to operate in 6 GHz for that country.
