57.14 Telnet
I cannot telnet into the IES-612-51.
57.15 Resetting the Defaults
If you lock yourself (and others) from the IES-612-51, 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.
57.15.1 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.
1 Connect to the console port using a computer with terminal emulation software. See
Section 3.2.1 on page 50 for details.
2 Enter your password.
3 Type
config restore.
4 Type
y at the question “Do you want to restore default ROM file(y/n)?”
5 The IES-612-51 restarts.
Table 165 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-612-51 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-612-51 uses for Telnet.
4 Ping the IES-612-51 from your computer.
If you are able to ping the IES-612-51 but are still unable to telnet, contact the distributor.
If you cannot ping the IES-612-51, 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.
