51.16 Resetting the Defaults

If you lock yourself (and others) from the IES-1248-51, 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
9600bps 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.

51.16.1 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
chapters
2 Enter your password.

CORRECTIVE ACTION
Make sure that the number maximum allowed number of telnet sessions has not already
reached. The IES-1248-51 only accepts up to five telnet sessions at a time.
Make sure that a telnet session is not already operating. The IES-1248-51 only accepts
one telnet session at a time.
Make sure that your computer's IP address matches a configured secured client IP
address (if configured). The IES-1248-51 immediately disconnects the telnet session if
secured host IP addresses are configured and your computer's IP address does not
match one of them.
Make sure that you have not disabled the Telnet service or changed the server port
number that the IES-1248-51 uses for Telnet.
Ping the IES-1248-51 from your computer.
If you are able to ping the IES-1248-51 but are still unable to telnet, contact the distributor.
If you cannot ping the IES-1248-51, check the cable, connections and IP configuration.
