4.2.2 Unexpected Radio Restart
This chapter
This chapter describes the process of troubleshooting and possible restart
triggers in case of an unexpected restart of the radio.
Radio restart
triggers
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)
Note:
The radio continuously checks if all modules of the radio are still alive
("watchdog"). If the radio detects that a certain module does not respond, it
tries to automatically reset the component/module. In most cases, this will
bring the radio back to normal operation.
In order to recognize the exact trigger of the radio restart, it is necessary to
analyze Event logs of the RX module 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
 439 RX PART a b c – indication of RX booted partition (RX only)
