Icannot telnet into the IES-612-51A.

Table 111 Troubleshooting Telnet

STEPS

CORRECTIVE ACTION

1

Make sure that the number of current telnet sessions does not exceed the maximum

 

allowed number. You cannot have more than five telnet sessions at one time.

 

 

2

Make sure that your computer’s IP address matches a configured secured client IP

 

address (if configured). The IES-612-51A immediately disconnects the telnet session if

 

secured host IP addresses are configured and your computer’s IP address does not

 

match one of them.

 

 

3

Make sure that you have not disabled the Telnet service or changed the server port

 

number that the IES-612-51A uses for Telnet.

 

 

4

Ping the IES-612-51A from your computer.

 

If you are able to ping the IES-612-51A but are still unable to telnet, contact the

 

distributor.

 

If you cannot ping the IES-612-51A, check the cable, connections and IP configuration.

 

 

5

Incorrectly configuring the access control settings may lock you out from using in-band

 

management. Try using the console port to reconfigure the system.

 

 

55.15 Resetting the Defaults

If you lock yourself (and others) from the IES-612-51A, you will need to reload the factory- default configuration file. Uploading the factory-default configuration file replaces the current configuration file with the factory-default configuration file. This means that you will lose all previous configurations and the speed of the console port will be reset to the default of 9600 bps with 8 data bit, no parity, one stop bit and flow control set to none. The user name will be reset to “admin” and the password will be reset to “1234” and the IP address to 192.168.1.1.

55.15.1 Resetting the Defaults Via Command

If you know the password, you can reload the factory-default configuration file via Command Line Interface (CLI) command. Use the following procedure.

1Connect to the console port using a computer with terminal emulation software. See Section 3.2.1 on page 50 for details.

2Enter your password.

3Type config restore.

4Type y at the question “Do you want to restore default ROM file(y/n)?”
