The meaning of the LEDs depends on the mode of operation (= boot or normal) in which the
NSM currently is running. After plugging in the module or rebooting it, the module turns into
the boot operation, see Table 3. After the module has rebooted successfully, after a few
seconds), the module turns into the normal operation, see LEDs in Table 4.
