6Device description
The FG8101G01 is a modular time reference system, which can serve most different
application cases by the supported hot-plug extension boards (in the following text only
called extension board/s).
A distinction is made between four functionalities that can be provided by extension
boards:
Power Supply Unit (PSU): Power supplyextension, which supplies the FG8101G01
with power.
Management Controller (MC for short): Management extension, with which the
FG8101G01 and all its extension boards can be managed.
Time Domain Controller (TDC for short): Time source extension, extension boards
with this functionality have a connector for a time source and supply the
FG8101G01 and the rest of the extension boards with a highly accurate time signal
Service Provider (SP for short): process the time signals provided by the TDCs and
thus generate a time output for the customer
Note
An extension board can provide more than one functionality.

6.1 Extension board positions
Figure 1
Figure 1 shows the rear panel of the FG8101G01, with labels for the individual positions
for extension boards from POS1 to POS8. The following table lists the functionalities that
are supported on the individual positions:
CAUTION
Extension boards positions
Extension boards fulfil their proper function only at the designated insertion
position in the system. However, if an extension boards is incorrectly
positioned, the rest of the system behaviour is not affected.

FG8101G01
Technical Documentation
Page 13 of 49 Version: 01.02; Date: 18.11.2022
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.

6.6 Minimal configuration of a FG8101G01
To operate a FG8101G01 as a time reference system the following functions must be
provided at least once by an extension board in the FG8101G01: PSU, MC, TDC, SP
Note: The MC functionality is only needed for the management (configuration and
monitoring) of the FG8101G01 and the extension boards and for the data indication on
the display of the FG8101G01. If the extension board with MC functionality is pulled out
of the FG8101G01 or fails due to a defect, then the time output of the extension boards
with SP functionality is not affected as long as one extension board with PSU and one
with TDC functionality are still operated in the FG8101G01.

6.7.1 LEDs
The LEDs show the current status of the FG8101G01.
If only the red LED is on, then there is an error in the FG8101G01 or at an extension
board.
If only the yellow LED is on, then there is a warning in the FG8101G01 or on an extension
board, but no error.
If only the green LED is on, then there are no errors or warnings in the FG8101G01 or at
the extension boards.
If all three LEDs are on, then no extension board with MC functionality is accessible from
the FG8101G01 (this is the case, for example, if the extension board with MC functionality
is booting).
Additionally, in the first 6 seconds after a reboot of the FG8101G01 aLED test is executed,
where always 2 LEDs are on at the same time. Starting with yellow and red, green and
red, green and yellow, then the run is performed one more time. Each combination is
displayed for one second.
6.7.2 Button
The button can be used to switch between the different screens on the display.
If the button is pressed briefly (100 to 500ms), the display switches to the next screen.
If the button remains pressed, an event is triggered every 500ms that simulates a short
button press. This way you can quickly scroll through all screens.
6.7.3 Display
With the help of the display the article and serial numbers of the FG8101G01 and the
extension boards can be queried, as well as basic information of the individual extension
boards.

FG8101G01
Technical Documentation
Page 16 of 49 Version: 01.02; Date: 18.11.2022
In the first 6 seconds after a reboot of the FG8101G01 a display test is performed, where
the backlight of the display is switched on and off and each of the 40x2 blocks of the
display is shown alternately empty and full.
After the display test, the FG8101G01 screen showing the part number and serial number
of the FG8101G01 on the display is shown for 30 seconds and the backlight is turned on.
Then the display goes into the IDLE state.
In the IDLE state all of the 40x2 blocks of the display are blank and the backlight is off. By
a short press of the button, depending on whether an extension board with MC
functionality is accessible from the FG8101G01, either the FG8101G01 screen (extension
board with MC functionality not accessible) or the TDC screen (extension board with MC
functionality accessible) is displayed.
The TDC screen displays the time information of the two TDC positions in the
FG8101G01. If there is no extension board with TDC function on POS2, then "TD1 -" is
displayed in the first line. If there is no extension board with TDC function on POS 6, then
"TD2 -" is displayed in the second line. Otherwise, the two lines will first display the
accuracy, then the date and time, as well as summer and winter time and leap second
changeover status from the corresponding TDC position. This screen is active for 30
seconds, then the display changes to the IDLE state unless the button is pressed within
the 30 seconds, in which case the display changes to the POS14 screen.
The POS14 screen displays the part numbers of the extension boards plugged into POS1
through POS4. This screen is active for 30 seconds, then the display will change to the
IDLE state unless the button is pressed within the 30 seconds, then it will change to the
POS58 screen.
The POS58 screen displays the part numbers of the extension boards plugged into POS5
through POS8. This screen is active for 30 seconds, then the display will change to the
IDLE state unless the button is pressed within the 30 seconds, then it will change to the
POS1 screen.

FG8101G01
Technical Documentation
Page 17 of 49 Version: 01.02; Date: 18.11.2022
The POS1 screen displays the part number of the extension board that is in POS1 and
status information that depends on the extension board type. This screen is active for 30
seconds, then the display changes to the IDLE state, unless the button is pressed within
the 30 seconds, then it changes to the POS2 screen.
The POS2 through POS8 screens are identical to the POS1 screen. The only differences
are the position for which they display the information and which screen is changed to by
pressing the button. It will always change to the next position number and from the POS8
screen it will change to the FG8101G01 screen.
If the button on the FG8101G01 screen is pressed within 30 seconds, the system changes
to the TDC screen, otherwise to the IDLE state.
