PTX10016 Switch Fabric

 

Switch Interface Boards (SIBs) create the switch fabric for the PTX10016. Each PTX10016 contains six SIBs that are installed vertically, mid-chassis, between the line cards and the Routing Control Boards (RCBs) in the front and the fan trays in the rear. When all six SIBs are installed, the PTX10016 has a net routing capacity of 96 Tbps.

PTX10016 Switch Interface Board Description

The SIBs make up the PTX10016 routing plane. Five SIBs are required for operation, with the sixth providing n+1 redundancy. The sixth SIB is powered and available to the system at all times. Each SIB has 16 connectors that match and connect to a connector on one of the 16 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, with SIB0 located next to the power supplies. See Figure 2.
