10.4.1 Double-Flash Indication of Function Changes
When upgrading from an earlier to a later software version, the behaviour of the
Operational indicator is always controlled by the earlier s oftware v ersion. After
the upgrade is finished, the installed software version controls the Operational
indicator.
When the Operational indicator is double-flashing on an RU, it means that
the RU is performing a function change and saving software in internal flash
memory.
This indication has been introduced because any disturbance of an RBS
performing a function change can corrupt the RU software. It is also very
important that all RUs in an RBS use the same software. Do not disturb any
RU or change any RU to Local mode while an RU is indicating a function
change. RUs continue to indicate function changes until a function change
restart takes place, unless:
• The software downloaded to the RU is identical to the software in RAM, in
which case the RU will stop indicating a function change after the download
is completed
• IXU is downloading software to the flash memory that is not intended to
execute on the IXU, in which case the IXU will only indicate a function
change while the file transfer is in progress
An RU without internal flash memory double-flashes while receiving software
even though it cannot store the software in flash memory.
Indication of a Function Change when Operational Indicator Is On
When a function change is initiated and the Operational indicator is on, it starts
to double-flash and shows a constant light during the so-called indicator old
