PTX10004 Switch Fabric

The PTX10004 Switch Interface Boards (SIBs) form the switch fabric for the router.

PTX10004 Switch Interface Board Description

Switch Interface Boards (SIBs) create the switch fabric for the PTX10004. The router contains between three and 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 PTX10004 switching plane that supports the 14.4-Tbps line card and operates in Junos OS Evolved systems. Each SIB has four connectors that correspond to a matching connector on one of the four line cards; see Figure 1.
