Configuring the H.100 or H.110 bus clock

If the boards are connected to each other on the H.100 or H.110 bus, set up a bus clock to synchronize communications between the boards connected to the bus. In addition, to provide redundant and fault-tolerant clocking between devices on the bus, configure alternative (fallback) clock sources to provide the clock signal if the primary source fails.

To configure the bus clock for a system:

Refer to CT bus clocking overview for more information. For specifics on setting up clocking for the boards, refer to the board documentation.

Clock Management EMC

The NMS OAM service provides H.100 and H.110 bus clock management services to boards in a chassis that is connected through the bus. This functionality is provided in the Clock Management EMC.

When the boards in a system are started, the Clock Management EMC:
