Chapter 12 Watchdog Function Settings
12.1 What is Watchdog Timer
Watchdog timer is an electronic timer that is used to detect and recover
computer from malfunctioning. When the computer is under normal operation, the
watchdog timer regularly resets and prevents the watchdog timer from timing out. If
there is an issue with the computer, the watchdog timer will eventually timeout, and
send out signal to initiate shutdown or reboot procedure, recovering the computer
from system failure. Watchdog timer operates independently from the computer,
making the failsafe mechanism more reliable.
*If the watchdog behavior is rebooting, please set the “Restore AC Power Loss”
option to “on”. Please refer to Chapter 11.3.
*To normal shutdown, please turn off the watchdog function to avoid
automatically boot situations.
