Data loss caused by incorrect switch-off with-
out UPS
In case of a missing UPS, switch off the control cabinet PC via the software of
the operating system only and not by interrupting the current supply. This ap-
plies particularly for RAID systems.
12.2 Operating and error displays
There are four LEDs on the connector panel of the IndraControl VPB 40.3 to dis-
play the device states and errors. Apply the specified measure if one of the fol-
lowing LEDs indicates either an error or a note, see tab. 12-1 "LEDs for ope-
rating and error display on the connector panel" on page 42.
Some LEDs, e.g. the CPU temperature monitoring, are only active if
the service software has been configured accordingly.
