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.

NSTALLATION
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.

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. 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.

:
The management agent accepts up to four simultaneous Telnet
sessions. If the maximum number of sessions already exists, an
additional Telnet connection will not be able to log into the system.
