GNSS Connection
The SyncServer S6x0 features a BNC connector for input from GNSS navigation
satellites to provide a frequency and time reference. This port also provides 9.7V
tothe power a Microsemi GNSS antenna (see Antenna Kits Overview in Appendix
C, Installing GNSS Antennas). See Figure 1-19. This connector is not present on
the SyncServer S650i.

NTP Input/Output Connections
The S600 / S650 has four dedicated and software isolated GbE Ethernet ports,
each equipped with NTP hardware time stamping. These are connected to a very
high-speed microprocessor and an accurate clock to assure high bandwidth NTP
performance. See Figure 1-20. See Appendix E, IP Port Details for information on
Ethernet port isolation and management port rules.

10 GbE Input/Output Connections
The S600 / S650 10 GbE option adds two SFP+ ports equipped with hardware
timestamping that supports NTP, PTP, and NTP Reflector operations. The 10 GbE
ports are in addition to the standard four 1 GbE ports for a total of 6 ports. These
ports are ideal for interoperability with 10 GbE switches. SFP modules supported
are limited to 10 GbE speeds only, and overall system time stamping capacity
remains as specified.
