2.1.8.6 Power-up LED Patterns
At power-up, the LEDs show the patterns described below. The LEDs also blink diagnostic patterns for
certain operating errors and for module identification. See the section on Special LED Blink Patterns above
for a description of the special blink patterns.

update. After the automatic update
completes, the LAN and STATUS
LEDs blink Amber and the module
resets, which restarts the power-up
process.

completed.
Note: Under certain ambient operating temperatures, the PROFINET Scanner may momentarily display
the over temperature pattern during power up, while it is calibrating its thermal protection
functions. This indication can be ignored. For details, refer to the section Microprocessor Over
Temperature above.
