MX10008 Switch Fabric Board
Switch Fabric Boards (SFBs) create the switch fabric for the MX10008. Each MX10008 contains six SFBs that are installed vertically, mid-chassis, between the line cards and the RCBs in the front and the fan trays in the rear. When all six SFBs are installed, the MX10008 has a net switching capacity of 42 terabytes.
MX10008 Switch Fabric Board Description
The SFBs make up the switching plane. Five SFBs are required for operation with the sixth providing N+1 redundancy. Each SFB has eight connectors that match and connect to a connector on one of the eight line cards. See Figure 1.
Table 1 shows the physical specifications for an MX10008 SFB.

SFBs are hot-removable and hot-insertable field-replaceable
units (FRUs). They are not visible from the outside of the router
chassis. You must remove one of the fan trays in order to view the
SFBs. The SFBs are numbered from left to right
SFB5. See Figure 2.
