Switch Fabric
Switch Interface Boards (SIBs) create the switch fabric for the PTX10004. Each SIB has a set of connectors
to mate the line cards and the Routing and Control Board (RCB) to the switch fabric. See
for an example of the JNP10004-SF3.
For the JNP10004 switch fabric, three SIBs provide the minimum switching functionality to a PTX10004
router; six SIBs provide full throughput. SIBs are installed between the line cards and the fan trays inside
the chassis. Each PTX10004 SIB has four connectors that match to a line-card slot, eliminating the need
for a backplane. See
"PTX10004 Switch Interface Board Description" on page
You can order the PTX10004 with different SIB configurations that allow you to grow your system as
needed. See
