IMPORTANT
After upgrade firmware of YFGW410 or YFGW510, check the all field wireless devices which
belong to the target device are joined to the network by the Monitor. Then carry out the download
firmware and apply to next backbone devices.
IMPORTANT
When upgrade YFGW510 firmware, carry out the download firmware and apply by model.
(1) The file size of YFGW410 firmware is larger than that of a field wireless device, and there-
fore there is an upload progress indication for transferring the file to the YFGW410.
(2) After a YFGW410 firmware update, if the Field Wireless Management Console version is
different, when the Monitor and the Configurator have accessed to the YFGW410, a closing
confirmation dialog appears.
(3) There are two ways to update YFGW410s or YFGW510s in a redundant configuration.
During downloading firmware, the PC which executes FWMC should be able to communi-
cate through field network with both of YFGW410s via the Layer2 switch. The procedure is
described as follows:
i. Upgrading firmware to one by one device
1. Check Active/Standby status of the YFGW410.
This explanation assumes that an initial status of “device A” is Active and “device B” is
Standby.
2. Carry out the firmware download for device B (Standby), and apply.
3. With the Change Active/Standby function, switch device A (Active) into the Standby.
Since device A and device B have different versions, when reconnecting the applica-
tion shows a closing confirmation message.
4. Carry out the firmware download for device A which was Standby, and apply.
5. Carry out the firmware download for YFGW510s, and apply.
To keep communications, select secondary YFGW510s at first. Several YFGW510s
can be carried out the firmware download and applying at the same time.
6. Carry out the firmware download for primary YFGW510s and apply.
ii. Upgrading firmware to YFGW410s or YFGW510s simultaneously
1. Select both of Active and Standby YFGW410s, and carry out the firmware download
and apply simultaneously.
In this case, all devices will be restarted.
2. Select all YFGW510s which is same model, and carry out the firmware download and
apply simultaneously.
(4) Carry out the firmware download and applying for backbone devices consecutively. The
download status is cleared by Applying process. If the download status is cleared, execute
download process again.
(5) For backbone devices, the downloads complete faster than for field wireless devices, and
therefore during the download there is no valid [Cancel Download] button. Once the down-
load completes cancel operation is available.
