By default, the system attempts to download or upload three
times until a successful download or upload. However, if a time is
specified for maximum download time and maximum upgrade time, multiple
attempts are made within the specified time until a successful download
or upgrade.
If the time set for Max Download Time and Max
Upgrade Time elapses while the download is in progress, the device
proceeds with the download until the operation is complete. If there
is a failure of any type, the upgrade process need to be rescheduled.
