OSM User's Guide (G06.27+)

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 (MSEBs) 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.
