A.2 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 internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective.
A.3 Installation
Verify that all system components are properly installed. If one or more components appear to be malfunctioning (for example the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.
A.4 In-Band Access
You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software tools. Do this by configuring the switch with a valid IP address, subnet mask, and default gateway. If you can not establish a link to the management agent, verify that there is a valid network connection, you entered the correct IP address, and that the port through which you are connecting to the switch has not been disabled. If it has not been disabled, check the network cabling that runs between the remote location and the switch.
