POWER SOURCES AND POWER CONSUMPTION

The AP supports direct DC power and Power over Ethernet (POE) on port E0 and/or E1

When POE power is supplied to both Ethernet ports, the AP combines power from both sources (SmartPOE feature), using E0 as the primary source and E1 as secondary

When both DC and POE power sources are available, DC power takes priority over POE

Power sources are sold separately; see the 650 Series Ordering Guide for details

The AP supports various power modes depending on the available power source(s) and configuration.

With IPM disabled, the AP may apply some static restrictions, see tables below.

With IPM enabled, the AP will start up in unrestricted mode but may dynamically apply restrictions depending on the available power budget and actual consumption.

When powered by direct DC power, the AP operates without restrictions.

Powering the AP from a single 802.3af (class 3 or lower) POE source is not supported, regardless of IPM status.

Maximum (worst-case) power consumption (without / with a USB device attached):

DC powered: 36.0W/42.5W.

POE powered: 40.3W/46.5W.

This assumes that up to 5W is supplied to the attached USB device.

Maximum (worst-case) power consumption in idle mode: 14.3W/20.2W (DC) or 16.9W/22.7W (POE).

Maximum (worst-case) power consumption in deep-sleep mode: 2.4W (DC) or 4.0W (POE).

MOUNTING

 A mounting bracket has been pre-installed on the back of the AP. This bracket is used to secure the AP to any of the mount kits (sold separately); see the 650 Series Ordering Guide for details.
