Functions of HiGig Interfaces

Hello,
The HiGig interface provides a communication channel for two adjacent ETHB boards to implement binding of two adjacent ETHB boards. Two adjacent ETHB boards can implement load sharing and redundant protection only after they are bound together.

Because MABA, MABC.VER A, MABH.VER B, and MABV.VER B backplanes do not provide the HiGig interface, the ETHB board provides such an interface on the front panel. The HiGig interfaces of two ETHB boards are connected by using an external mini SAS high-speed cable. In this way, the two ETHB boards can communicate with each other. To set two ETHB boards to be in a protect group or to implement load sharing between two ETHB boards, connect their HiGig interfaces.

The MABC.VER B and MABH.VER C backplanes provide the HiGig interface. Therefore, two adjacent ETHB boards can communicate with each other through the backplane directly and they can implement binding without external mini SAS high-speed cables.
