4.4 Device Lockout
You can be locked out from managing the OLT if another administrator is currently logged in
with the
admin user name. You must wait until the other administrator has logged out before
you can log in.
Any of the following could also lock you and others out from using out-of-band management
(managing through the console port or management port).
1 Misconfiguring the text configuration file.
2 Forgetting the password and/or management IP address.
3 Preventing all services from accessing the OLT.
4 Incorrectly configuring the access control settings.
5 Changing a service port number but forgetting it.
"
Be careful not to lock yourself and others out of the OLT.
4.5 Resetting the OLT
If you lock yourself (and others) from the OLT or forget the administrator password, you will
need to reload the factory-default configuration file or reset the OLT back to the factory
defaults.
4.5.1 Reload the 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 password will also be reset to
1234 and
the default out-of-band management IP address to 192.168.0.1 .
