Figure 5: PTX10K-LC1102 Line Card
Switch Interface Boards
Five switch interface boards (SIBs) provide the necessary switching functionality to a PTX10008 router
(see Figure 6 on page 30). A sixth SIB is available in the redundant configuration to provide n+1 redundancy.
SIBs are installed between the line cards and the fan trays inside the chassis . Each PTX10008 SIB has
eight connectors that match to a line card slot, eliminating the need for a backplane. See “PTX10008 Switch
Interface Board Description” on page 86.
There are two models of SIB, each is available in a base bundle and redundant configuration. The
JNP10008-SF is the standard SIB, see Figure 6 on page 30 The enhanced SIB, (JNP10008–SF3) supports
14.4 Tbps line cards, see Figure 7 on page 31.
