8. Software Upgrade

The Master AU consolidates the management of software upgrades for the entire system and saves the last software

package for the AU, EU and RU. Slave devices compare the local software with that saved in the Master AU at run time. If

the software version is different, the slave device will start the software upgrade progress and reset automatically after

the upgrade is complete. The benefit of this approach is that if a slave device is replaced, a software upgrade is started

automatically without having to do additional operations. If the Master AU is replaced, before connecting the new

Master AU to the system, check the software version using the WebOMT as shown in Figure 8-1. If the software version

is not the latest version, upload the latest software packages to the new Master AU.

Figure 8-1 Checking Software Package Version

As mentioned above, the system software upgrade is divided into two steps. First, upload the package to the master

AU. Second, the slave device automatically downloads the new software package from the Master AU to complete the

upgrade process. This process can be performed in one of two ways: by performing a local upgrade using the OMT or by

performing a remote upgrade via FTP.

8.1. Local Upgrade

As an example, to do an RU or EU upgrade:

1. Log in to the WebOMT on the Master AU. Click the Upgrading button on the main page to navigate to the

software upgrade page. See Figure 8-2.
