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, 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. 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.
Note: The Telnet user interface supports one connection. A user will be
disconnected immediately when there is already one session
running Telnet. The Telnet session requires the same log-in
procedure as the console interface session.
