Cisco Aironet Series Power Injector AIR-PWRINJ1500-2= Installation Instructions
Checking the Power Injector LEDs
Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports
contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution
when connecting cables.
Statement 1021
Note
The power injector Ethernet cables are limited to a total length 328 ft (100 m) maximum from
the switch to the access point. Also, the Ethernet cable from the power injector to the access
point is limited to a minimum of 10 ft.
Note
The PoE-out port on the access point is disabled when using the power injector.
Step 5
Plug an appropriate power cord into the three-pronged receptacle on the end of the Power Injector
Step 6
Connect the other end of the power cord into a 100-VAC to 240-VAC power source
Checking the Power Injector LEDs
You can use the power injector LEDs to assess the unit status. Two indications are available: solid green
or dark. The LED descriptions are:
•
AP POWER—Turns solid green after successful discovery; indicates that power injector is
supplying power to the access point.
•
FAULT—Turns solid red when a fault is experienced during discovery mode or power-up.
•
AC POWER—Turns solid green when power injector is receiving AC power and is ready to provide
power to the access point.
