You can use the power injector LEDs to check the power injector status. The LEDs provide the following
status information:

supplying power to the access point.
• FAULT—Turns solid red when a fault occurs during discovery mode or power-up. Check Ethernet
cables and connections before contacting your support organization for assistance.
• AC POWER—Turns solid green when power injector is receiving AC power and is ready to provide
power to the access point.
