Troubleshooting

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 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.

Caution: The management agent can accept 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.
