Power
Both Ethernet ports support PoE-in, allowing the AP to draw power from an 802.3at/802.3bt PoE power
source. When the AP is powered by both E0 and E1 ports simultaneously, the AP can be configured by
management software to source PoE power from either port, or to combine power from both ports.
If PoE is not available, a proprietary AP-AC2-12B power adapter or AP-AC2-48C adapter (sold separately) can be
used to power the access point. When both PoE and DC power sources are available, the DC power source
takes precedence. In that case, the access point simultaneously draws a minimal current from the PoE source.
In the event that the DC source fails, the access point switches to the PoE sources.
The 650 Series access points support the Intelligent Power Monitoring (IPM) feature, to report AP power
consumption and enable intelligent management of power-save capabilities.
lists operational restrictions when the AP is powered by different power options.

FCC Statement:
Improper termination of access points installed in the United States configured to non-US model con-
trollers will be in violation of the FCC grant of equipment authorization. Any such willful or intentional violation may res-
ult in a requirement by the FCC for immediate termination of operation and may be subject to forfeiture (47 CFR 1.80).
