Under-current indication < 8 mA
Over-current indication > 80 mA
Note: This alarm condition will also be present if a GNSS antenna split-
ter that does not contain a load to simulate an antenna being present
is being used.
GPS Antenna OK : The antenna coax cable was just connected or an open or
short in the antenna cable was being detected but is no longer being detected.
Frequency Error : The oscillator’s frequency was measured and the frequency
error was too large. Or, the frequency couldn’t be measured because a valid input
reference was not available.
Frequency Error cleared : The Frequency Error alarm was asserted but was
then cleared.
In Holdover : Input references were available, but all input references have since
been lost. If the references are not restored before the Holdover period expires,
time sync will be lost.
No longer in Holdover : Input references were lost at one point (or declared not
valid), but have since been restored OR the Input references were not restored
before the Holdover period expired (Time Sync alarm is asserted).
In Sync : VelaSync is synchronized to its Time and 1PPS inputs.
Not In Sync : VelaSync is not synchronized to its Time and 1PPS inputs and is not
currently in Holdover. NTP will indicate to the network that it is Stratum 15 and so
the time server likely be ignored as a time reference.
Sending trap for event 1 (SNMPSAD) : An SNMP trap was sent by the SNMP
agent to the SNMP Manager. The event number in this entry indicates which
SNMP trap was sent.
The Unit has Rebooted : VelaSync was either rebooted or power cycled.
Journal Log
Displays log entries created for all configuration changes that have occurred (such as
creating a new user account, for example).
NTP Log
The NTP log displays operational information about the NTP daemon, as well as NTP
throughput statistics (e.g., packets/sec.). Examples for entries in this log include indic-
ations for when NTP was synchronized to its configured references (e.g., it became a
Stratum 1 time server), as well as stratum level of the NTP references.
