USB Download
If the radio is updated via USB interface, always the first partition is
updated. The Service and Maintenance Tool R&S ZS 4200 switches the
radio into an update mode, which interrupts the operation and disables all
interfaces.
After the software download the radio always boots from the partition 1.
Remote Download
via LAN
The software download on the LAN interface can be done in parallel to the
operation of the radio. The update is always done into the partition which
was not used for booting. This means that if the radio was booted from the
partition 1, the remote download will be done into the partition 2 and vice
versa.
After the download has been completed the user can choose when to
switch the radio into the updated partition. This is done by selecting the
partition which has been updated as the boot partition and then
commanding the radio to reboot. Then, the radio always reboots from the
same partition until the partition is changed manually via a remote control
command.
Recovery
mechanism
The radio is equipped with a recovery mechanism. In two defined situations,
the radio will automatically switch from one partition and try to boot the
other, currently an inactive partition:
1.
The radio is rebooted after a software update and this reboot fail.
2.
The user manually switches the partition and the succeeding reboot
fails.
Note:
The normal booting time of the radio is less than 1 minute.
