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. If you still
cannot isolate the problem, the internal power supply 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 switch from anywhere within the
attached network using a web browser, or other network management software
tools. However, you must first configure the switch 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 port through
which you are connecting to the switch has not been disabled. If it has not been
disabled, then check the network cabling that runs between your remote
location and the switch.
