Power Sources

The access point can receive power from an external power module or from inline power using the
Ethernet cable. The access point supports the IEEE 802.3af inline power standard and Cisco CDP Power
Negotiation. Using inline power, you do not need to run a power cord to the access point because power
is supplied over the Ethernet cable.
Warning This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source
or an IEC60950 compliant limited power source. Statement 353
Caution Be careful when handling the access point; the bottom plate might be hot.
The access point supports the following power sources:
•
•
Some switches and patch panels might not provide enough power to operate the access point with both
Note
2.4-GHz and 5-GHz radios. At power-up, if the access point is unable to determine that the power source
can supply sufficient power, the access point automatically deactivates both radios to prevent an
over-current condition. The access point also activates a Status LED low power error indication and
creates an error log entry (refer to the

The Status LED provides general operating status and error indications.
The Ethernet LED signals Ethernet traffic on the wired Ethernet LAN and provides Ethernet error
indications.
The Radio LED signals that wireless packets are being transmitted or received over the radio
interface and provides radio error indications.
