6. Download the changed configuration data from the Configurator to the YFGW410.
7. On the Monitor, check that all the devices, including the added device, and communication
paths are normal.
When replacing the YFGW410 that is judged to be defective by the host system warning function
or the Monitor’s analysis result, perform the following procedure.
l Single system
If the YFGW410 is judged to be defective, immediately replace it with the spare device to make a
recovery.
1. If the YFGW410 to be replaced is a used product, initialize the database.
2. Install the new device and conduct wiring instead of the defective product at the site.
3. Connect the PC to the maintenance interface, and start the Configurator of the Field Wire-
less Management Console using the factory default IP address.
4. After the system has been set up or if any change has been made for maintenance, import
the backup file of the last saved wireless network configuration data to the Configurator.
5. Check the configurations, and download it to the YFGW410.
6. On the Monitor, check that all the devices, including the replaced device, and communica-
tion paths are normal.
l Redundant system
In the YFGW410-redundant system, if one YFGW410 becomes abnormal, another one contin-
ues operations instead. As a precaution, replace the defective device at an early date to recover
the system.
1. If the YFGW410 to be replaced is a used product, initialize the database.
2. Replace the defective device with a new one, and conduct the installation and wiring.
3. Turn the power on.
4. On the Monitor, check that all the devices, including the replaced device, and communica-
tion paths are normal.
IMPORTANT
For details of initializing the database, see B3.6 Reset Switch.
IMPORTANT
To use Field Wireless Management Console during an operational state, it should be executed
on the PC which can access to YFGW410 through field network interfaces.
