Parameter
Section 5.1.2
Managing NTP
RUGGEDCOM ROS may be configured to refer periodically to a specified NTP server to correct any accumulated
drift in the on-board clock. RUGGEDCOM ROS will also serve time via the Simple Network Time Protocol (SNTP) to
hosts that request it.
Two NTP servers (primary and backup) may be configured for the device. The primary server is contacted first for
each attempt to update the system time. If the primary server fails to respond, the backup server is contacted. If
either the primary or backup server fails to respond, an alarm is raised.
