POWER ON
Lights up green after the system power controller has completed the power-up sequence without error. In the standby status the indicator flashes.
SYSTEM
Lights up green when the CPU(s) is/are in operation.
CHECK
Lights up red when the SVP has detected a hardware malfunction or a fault in the power supply of the SU /390. In the event of a fault a buzzer sounds at the same time.
STATUS indicator
Depending on the POWER ON indicator, this indicator is switched on and displays details of the hardware status with a three-character alphanumeric display.
The display changes as sequences are executed. If the display finally stops at a particular value not equal to "000", this must be interpreted as the error code for a problem. In this case Customer Support should be contacted.
