About erasing the configuration
The following procedures erase the B5800 Branch Gateway configuration stored in the control
unit. This includes both the current configuration being used in RAM memory and the backup
configuration stored in non-volatile memory. Following this, the B5800 Branch Gateway will
restart with a default configuration.
These procedures should be performed from a PC with a fixed IP address, directly connected
to the B5800 Branch Gateway control unit and with the B5800 Branch Gateway system
disconnected from any network. The control unit IP address will default to 192.168.42.1.
Important:
Do not perform any of these processes unless absolutely necessary. The configuration
settings can be returned to the default settings using Manager by selecting File > Advanced
> Erase Configuration command.
