Switch Fabric Boards
Switch Fabric Boards (SFBs) create the switch fabric for the MX10004. Each SFB has a set of connectors
to mate the line cards and the Routing and Control Board (RCB) to the switch fabric. See
Figure 4 on
page 6
for an example of the JNP10004-SF2 Switch Fabric Board.
For the MX10004 switch fabric, three SFBs provide reduced switching functionality to an MX10004
router. Six SFBs provide full throughput. You install the SFBs between the line cards and the fan trays
inside the chassis. Each MX10004 SFB has four connectors. Each connector matches up with a line card
slot, eliminating the need for a backplane.
