About NTP Associations
The SyncServer's factory configuration includes three NTP associations:
The Hardware Clock makes a timing reference source (e.g., GPS, Timecode) available to
n
the NTP daemon as an NTP association. The Hardware Clock NTP association is
always preferred and cannot be edited or deleted. See TIMING - HW Clock (on page
42) for more information.
Having multiple associations is important for obtaining the best reliability and accuracy from
the SyncServer's NTP daemon. The SyncServer uses the NTP associations to qualify one
another; synchronizing with the best one and rejecting any that provide the incorrect time. If
the Hardware Clock runs without an Input Reference for a sustained period of time, the Syn-
cServer synchronizes with one of the NTP servers instead.
Configuring NTP Associations
If the following conditions are true, the user does not need to reconfigure NTP:
LAN1 is connected to the network and has Internet access through firewall port 123.
n
GPS is set up correctly and operating as a reference source.
n
No NTP servers are available on the local or wide area network.
