21.5 Resetting the Defaults
You can upload the factory-default configuration file to reset the OMC to the default settings.

be reset to the default of 115200 bps with 8 data bit, no parity, one stop bit and flow control set
to none. The user name and password will also be reset to “admin” and “1234”. The default
out-of-band IP address is 192.168.0.1.
