PTX10008 Switch Fabric

 

The PTX10000 Switch Interface Boards (SIBs) form the switch fabric for the router.

PTX10008 Switch Interface Board Description

Switch Interface Boards (SIBs) create the switch fabric for the PTX10008. Each PTX10008 contains five or six SIBs that are installed vertically, mid-chassis, between the line cards and the RCBs in the front and the fan trays in the rear.

The SIBs make up the PTX10008 switching plane. Five SIBs are required for operation with the sixth providing n+1 redundancy. When all six SIBs are installed, the PTX10008 has a net switching capacity of 42 terabits. Each SIB has eight connectors that match and connect to a connector on one of the eight line cards. See Figure 1.

SIBs 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 SIBs. The SIBs are numbered from left to right SIB0 to SIB5. See Figure 2.
