9. Software Upgrade
The Master AU consolidates the management of software upgrades for the entire system and saves the
last software package information for AU, EU-E and NPRU shown as Figure 9-1. Slave devices will
compare the local software with latest information saved in Master AU by checking CRC at run time. If the
CRC is different, slave devices will be synchronized via current software package from Master AU.
Therefore, when a slave device is replaced, its software will be upgraded automatically without any
additional operation.
Note: If it is the Master AU to be replaced in a system, check software version of the new Master AU before
connecting it to the system. If the software version is not the latest version, upload the latest software
packages to the new Master AU.
