Cisco Cisco Aironet 1522 Lightweight Outdoor Mesh Access Point 설치 가이드

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 6 ampere-hour battery

The access point can be connected to more than one power source. The access point detects available 
input sources and switches to the preferred power source using the following prioritization:

AC or POC power

External DC power

1520 power injector PoE power

To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. 
Statement 1023

To provide inline PoE, you must use the 1520 series power injector. Other power 
injectors, PoE switches, and 802.3af power sources cannot provide adequate power, 
which may cause the access point to malfunction and cause over-current conditions at the 
power source. You must ensure that the switch port connected to the access point has PoE 
turned off.

Do not install the power injector and the power outdoors. They must be installed indoors.

When the access point is installed outdoors or in a wet or damp location, the AC branch

(GFCI), as required by Article 210 of the National Electrical Code (NEC).

Three AC power cord options are available:
