Power draw

• 20.9W

Note: When deployed using a Power over Ethernet (PoE) specification, the power drawn from the power sourcing equipment will be higher by some amount, depending on the length of the interconnecting cable.

Powering options

• 802.3at
• Enhanced PoE
• Cisco power injector, AIR-PWRINJ4=
• Cisco local power supply, AIR-PWR-C=
• Cisco power injector, AIR-PWRINJ5= (Note:this injector supports 802.3af only)
• 802.3af

Note: If 802.3af PoE is the source of power, (1) the 1852e 2.4-GHz radio will shift to 2x3 from 3x4, (2) The USB port and AUX Ethernet port are disabled on both the 1852i and 1852e.
