6.2
PSU - Power Supply Unit
Up to 2 PSUs are supported in FG8101G01. A PSU converts the voltage on its supply
voltage input connector(s) to the device internal supply voltage.
If two PSUs are operated in one FG8101G01, then a 1 out of 2 redundancy is obtained.
6.3
MC - Management Controller Board
In FG8101G01 one MC is supported. The MC distributes the configuration and updates
and collects the status of the FG8101G01 and the remaining extension boards via the
internal management bus. Additionally, the MC provides parts of the collected status via
the display of the FG8101G01.
6.4
TDC - Time Domain Controller Board
In FG8101G01 up to 2 TDCs are supported. One TDC processes the time signal
connected to the corresponding connector of the TDC extension boards, converts it to an
internal protocol, which is routed to the FG8101G01 and the remaining extension boards
via a TDC interface.
FG8101G01 has two TDC interfaces, each of which is routed to all extension boards in
the FG8101G01.
6.5
SP - Service Provider
In FG8101G01 up to 6 SP are supported. A SP synchronizes to one of the two TDC
interfaces and thus generates its time output (e.g. NTP).
Each SP can also synchronize to both TDC interfaces of the FG8101G01 and thus
generate its time output. Which TDC interface is the primary synchronization source of a
SP can be configured per SP.
