Restart and Recovery
24 bring DMRU into remote operation
Start processor:
•
If the checksum for the updated application software is correct,
the updated application is chosen as application software.
• If the RU is a DMRU without non-volatile memory, the DMRU
must retrieve software from the CMRU.
•
If database parameters are not useable, are inaccessible or out of
range, default values are used instead.
Termination of start processor:
Terminated when the updated application software has started correctly,
or with a new reset. If there are problems in starting updated application
software, then the base application is chosen as application software.
35.4 Operational Conditions
35.4.1 Operation and Maintenance
Maintenance functions related to restart and recovery are described in
chapter Operation and Maintenance Terminal. The visual indicators
relevant to restart and recovery are described in chapter Operation and
Maintenance Support Functions. All of the visual indicators associated
with a RU are temporarily turned on for a minimum of 2 seconds
during the initial restart of that RU. This allows visual identification of
any faulty indicators.
35.4.2 Capabilities
The start time is defined as the time elapsed from when the power is
turned on (after having been off), or from the reception of reset (reset
button pushed or BSC reset order received) to when the RBS is ready to
be taken into remote mode. Depending on the reason for restart, certain
actions must be taken during start up, which results in various start-up
times. Restart time after BSC ordered reset is less than 8 seconds if all
RUs are preloaded with software with correct revision and a correct
RBS DB is installed. For all other restart cases with a heated oscillator,
restart time of the whole RBS is about half a minute. For the restart
case with a cold oscillator (power on), restart time of the whole RBS is
about 5 minutes. For information of the temperature influence on start
up time and the delay caused by the environment control unit, see
chapter Unit Description, ECU.
