HP NonStop G-Series - Manual (Page 237)

A hardware component that provides connectivity for multiple nodes of a second-generation
ServerNet cluster using the layered topology. As part of the layered topology, the 6780 switch
module comprises one cluster switch layer within a cluster switch group. The 6780 switch
connects to the nodes through fiber-optic cables that connect to modular ServerNet expansion
boards (
MSEB s) on each node.
The subcomponents of the 6780 switch module are the Switch Logic Board , Switch PICs ,
Switch Ports , Switch Power Supply , and Switch Fan .
