10.1.3 Upgrade firmware
The firmware is stored in the flash memory and can be updated with new versions to include new features
or to modify the existing one. This UBR has two partitions. The new firmware version is always uploaded
in the alternate partition (Backup Bank) to keep the current firmware image restored which is located in
the current partition (Active Bank) of UBR. When we upgrade the device with new firmware, the device
reboots and the new firmware from the alternate drive becomes the active firmware in current partition
(Active Bank) and the old firmware becomes the backup firmware in alternate drive (Backup Bank). If
any issues found in new firmware, the backup firmware will be booted.
A basic overview of the Backup/Flash Firmware screen to upgrade the firmware from an external file is
