Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation Guide
OL-12632-03
Chapter1 Overview
Hardware Features
Multiple Power Sources
The access point supports these power sources:
•PoE—power injector (AIR-PWRINJ1500-2=)
•AC power—100 to 480 VAC (standard power source for the pole mount configuration)
•POC—40 to 90 VAC (quasi-square wave AC), (standard power source for the cable configuration)
•External 12 VDC
Warning
Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV)
requirements in IEC 60950 based safety standards.
Statement 1033
•Internal battery
The access point can be connected to more than one power source. The access point detects the available
power sources and switches to the preferred power source using the following default prioritization:
•AC power or POC power
•External 12-VDC power
•Power injector PoE power
•Internal battery power
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.
Statement 1028
Caution To provide inline PoE, you must use the 1520 power injector (AIR-PWRINJ1500-2=). Other power
injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which can cause the
access point to malfunction and cause over-current conditions at the power source.
Caution The 1520 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only.
Note In the cable configuration, the cable modem is activated only when the access point is powered by POC
or external 12 VDC power. When using only PoE power, the cable modem is deactivated.
