2. Move the reference which has “GPS 0” in the Time column and “GPS 0” in
the 1PPS column to the top of the table, with a Priority value of 1. Click the
Enabled checkbox.
3. Move the reference which has “GPS 0” in the Time column and “GPS 0” in
the 1PPS column to the top of the table, with a Priority value of 1. Click the
Enabled checkbox.
Since both of these references are default references, no additional references
need to be added to the Reference Priority table.
Example 2 – IRIG as primary reference, NTP input as backup
In this use case, the objective is to use:
IRIG as the primary reference input
Another NTP server as backup reference
Step-by-step procedure:
1. Move the reference which has “IRIG 0” in both the Time column and “IRIG
0” in the 1PPS column to the top of the table, with a Priority value of 1. Click
the Enabled checkbox.
2. Move the reference which has “NTP” in the Time column and “NTP” in the
1PPS column to the second place in the table, with a Priority value of 2.
Click the Enabled checkbox.
3. For all other references, uncheck the Enabled checkbox, so that they are all
disabled.
Since both of these references are default references, no additional references
need to be added to the Reference Priority table.
Example 3 – NTP input as the only available input (“NTP Stratum2
operation”)
In this use case, the objective is to have NTP provided by another NTP server as
the only available reference input, i.e. the unit to be configured is operated as a
Stratum 2 server. For more information, see "Configuring "NTP Stratum Syn-
chronization"" on page117.
Step-by-step procedure:
1. Move the reference which has “NTP” in the Time column and “NTP” in the
1PPS column to the top of the table, with a Priority value of 1. Click the
Enabled checkbox.
