Operating temperature for the display
To increase the service life of the display, the display switches off when the permitted
operating temperature is exceeded. When the display has cooled down again, it switches
back on automatically. When the display is switched off, the LEDs continue to show the
status of the CPUs.
You can find additional information on display temperatures in the technical specifications in
the CPU manuals.
