Upgrading the ODU Software
The EtherHaul system supports switching in real time between two software versions.
EtherHaul maintains an active (running) and a standby software version simultaneously.
This enables you to upgrade the software with minimal interruption of service.
An external FTP server is required for software download. When you download a
software version, the downloaded version replaces the standby version.
