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.

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 SFB0 to SFB5. See Figure 2.
