Checking IDB Configuration
1. In the Maintenance menu in OMT, select Check IDB to display possible
inconsistencies between the HW and the IDB. Ensure that the IDB
configuration is in accordance with the HW cabinet configuration regarding
defined power system and climate system.
Checking Climate
2. Inspect the airflow path in the RBS, and ensure that the airflow is not
obstructed.
3. If the temperature is between 45 and 55° C, install a fan unit. For more
information, see Chapter Installation of RBS in this manual.
4. If the temperature is below −15°C, then the RBS must be powered with
AC. AC power is needed for the RBS to start the heater.
Note: RBS units from certain R-states are less sensitive to low temperatures
and have therefore no internal heater. For more information about unit
R-states from which these improvements apply, see chapter Product
