By Applying a firmware, devices will restart automatically. Care should be taken because restart-
ing a device having a relay function within the field wireless network may affect all connected
devices below this device in the hierarchy.
There are ISA100.11a field wireless devices provided by other manufacturers which do not auto-
matically restart after applying a firmware. In this case, restart devices manually. For the method
of manually restarting, see “Select Restart Devices” in this sub-section.
IMPORTANT
Even if the Firmware Download Manager is closed, the firmware update process is running in
background. However if the Monitor is closed, all status of firmware update will be cleared. So
do not close the Monitor before not completing firmware update process. A firmware download
may take a considerable time, so it requires to care when closing the window during a firmware
download to carry out another operation, until the firmware update process is completed.
