Juniper Networks QFX10016-SF Switch fabric card / Switch Interface Board, pulled from new, never installed configuration – tested prior to pull. 

Five switch interface boards (SIBs) provide the necessary switching functionality to a base configuration QFX10016. A sixth SIB is available in the redundant configuration to provide n+1 redundancy. SIBs are installed between the line cards and the fan trays inside of the chassis. 

Each QFX10016 SIB has 16 connectors that match to a line card slot, eliminating the need for a backplane. When all six SIBs are installed, the QFX10016 has a net switching capacity of 96 Tbps.
