## Voltage measurements

System voltages can be measured either using the RASC tool (menu systems- ad-converters) or directly on the backplane. As it is possible to cause a short on the lines during measurement all boards in the cabinet should be removed. Test points on the backplane are accessible only if the CPU-D_ in position 0 is removed (refer to document 1531-BDV11308 for details).
