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.
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 Telnet, a Web
browser, or other network management software. 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.
