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. In this case, contact SMC Technical
Support for assistance.
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 such as
EliteView. 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.
