Cisco Aironet Series Power Injector AIR-PWRINJ1500-2= Installation Instructions
Overview
Warning
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

Statement 1074
Caution
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.
Caution
The power injector AC power receptacle must be accessible at all times, as it serves as the main
disconnect device to the unit.
Overview
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.
