6.2 Power 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 or power loss or surging at the power source.
6.3 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.
6.4 In-Band Access
You can access the management agent in the switch from anywhere within the
attached network using Telnet or 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 the remote location and the switch.
Note: The management agent can accept up to four simultaneous Telnet sessions. If the
maximum number of sessions already exists, an addition Telnet connection will not be able
to log in to the system.
