Cisco Cisco Aironet 1552WU Outdoor Access Point 설치 가이드

To prevent the system from overheating, do not operate it in an area that exceeds the maximum 
recommended ambient temperature of: 131F (55C) Statement 1047

 

3 to 4 inches (7.6 to 10.1 centimeters) Statement 1076

Installation of the equipment must comply with local and national electrical codes. Statement 1074

Do not place the power injector in an unprotected outdoor environment because water could get into the 
power injector and cause a short circuit and possible fire.

The power injector AC power receptacle must be accessible at all times, as it serves as the main 
disconnect device to the unit.

The power injector combines 56-VDC power (supplied by internal power supply) with the data signal, 
sending both to the access point. The power injector provides up to 80 W over all four wire pairs of 
shielded, outdoor rated Ethernet cable. 

Ensure that the length of the Ethernet cable from the AP to the power injector is more than 10 ft (3 m), 
but less than 140 ft (42 m). The total length of the cable from the AP to the switch must not exceed 320 
ft (100 m). The wire gauge of the cable must be 26 AWG.

The Ethernet cable from the switch to the power injector must be a shielded CAT5e or higher Ethernet 
cable. The Ethernet cable from the power injector to the access point must be a shielded outdoor-rated 
CAT5e or higher Ethernet cable with a 0.20 to 0.35 inch diameter. 

A shielded, outdoor Ethernet cable connects the power injector to a 10/100/1000 Ethernet switch, hub, 
or network, and another shielded, outdoor cable carries power and data to the access point’s Ethernet 
port. The power injector’s AC power receptacle connects an approved AC power cord to a wall outlet or 
power strip. The power injector can be mounted on most horizontal and vertical surfaces, but must be 
mounted in a vertical orientation to comply with safety requirements.
