Chapter 5
Troubleshooting Lightweight Access Points
Checking Power
The power injector is available in two models:
Cisco Aironet Power Injector LR2—standard version (included with the access point)
48-VDC input power
Uses the 48-VDC power module (included with the access point)
Cisco Aironet Power Injector LR2T—optional transportation version
12- to 40-VDC input power
Checking Power
You can verify the availability of power to the lightweight access point by checking the power injector
LED (see
Figure 5-2
):
Power LED
Green color indicates input power is being supplied to the access point.
Red color indicates an overcurrent or overvoltage error condition—disconnect input power from
the power injector, check all coax cable connections for a possible short, wait approximately
1 minute, and reconnect input power to the power injector. If the LED turns red again, contact
technical support for assistance.
Note
The power injector requires approximately 50 seconds to recover from an overcurrent or
overvoltage condition.
Off indicates input power is not available—verify that the power module is connected to the
power injector and that AC power is available or that 12- to 40-VDC input power is connected
to the power injector.
Using DHCP Option 43
You can use DHCP Option 43 to provide a list of controller IP addresses to the lightweight access points,
enabling the access point to find and associate with a controller. For additional information, refer to the
“Configuring DHCP Option 43 for Lightweight Access Points” section on page G-1
