Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in, you

may have a problem with the power outlet, power cord, or power supply unit.

However, if the unit powers off after running for a while, check for loose power

connections, power losses or surges at the power outlet. If you still cannot isolate

the problem, the power supply unit may be defective.

Installation

Verify that all system components have been properly installed. If one or more

components appear to be malfunctioning (such as the power cord or network

cabling), test them in an alternate environment where you are sure that all the

other components are functioning properly.

In-Band Access

You can access the management agent in the wireless controller through a

connection to any port using Telnet, a web browser, or other network management

software tools. However, you must first configure the wireless controller with a valid

IP address, subnet mask, and default gateway. If you have trouble establishing a

link to the management agent, check to see if you have a valid network connection.

Then verify that you entered the correct IP address. Also, be sure the wireless

controller port has not been disabled. If it has not been disabled, then check the

network cabling that runs between your remote location and the wireless

controller.
