Unexpected Radio Restart

W –
This chapter describes the process of troubleshooting and possible restart
triggers in case of an unexpected restart of the radio.
There are two main radio restart triggers:

External triggers (can be requested, e.g. user, remote client; or
unrequested, e.g. power line interruption)

Internal triggers (always unrequested, e.g. WatchDog (WD), Partition
Management)
In order to recognize the exact trigger of the radio restart, it is necessary to
analyze Event logs of the TX and RX modules of the radio.
Every time the radio restarts (or is powered up), it stores the restart-related
events in the event logs at a certain point of booting process:

001 RESTART – indication of radio restart

110 MMI PART a b c – indication of MMI booted partition

351 TX PART a b c – indication of TX booted partition (TX only)

439 RX PART a b c – indication of RX booted partition (RX only)
Note
After RC client sends
an RST command to
RX module, but before
reboot.
