Checking Power

Checking Power

You can verify the availability of power to the access point/bridge by checking the power injector LED (see Figure 7-2):

•Power LED

–Green color indicates input power is being supplied to the bridge.

–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.

Checking Basic Configuration Settings

Mismatched basic settings are the most common causes of lost wireless connectivity. Check the following areas.

Default IP Address Behavior

When you connect an access point/bridge running Cisco IOS Release 12.3(2)JA or later software with a default configuration to your LAN, the access point/bridge requests an IP address from your DHCP server and, if it does not receive an IP address, continues to send requests indefinitely. To eliminate this behavior, you must access the access point/bridge through its console port and assign a static IP address.

When you connect an access point/bridge running Cisco IOS Release 12.2(15)JA2 or earlier software with a default configuration to your LAN, the access point/bridge requests an IP address from your DHCP server and, if it does not receive an IP address, it assigns a default IP address of 10.0.0.1

Default SSID and Radio Behavior

In Cisco IOS Release 12.3(2)JA2 and earlier, on initial power up the access point/bridge defaults to the Install-Mode role with the radio enabled and supports these SSIDs:

•SSID is autoinstall for the Install-Mode role.

•SSID is tsunami for Root AP and Workgroup Bridge roles.

In Cisco IOS Release 12.3(4)JA, on initial power up the access point/bridge defaults to the Root AP role with the radio disabled and no default SSID configured.
