PTX10008 Switch Fabric

The PTX10008 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 between five 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 PTX10008 switching plane. There are two models of SIBs: the JNP10008-SF (see Figure 1) and the JNP10008-SF3 (see Figure 2). SIBs must all be of the same model type in a running chassis. On both models, the SIB has eight connectors that match and connect to a connector on one of the eight line cards. The JNP10008-SF SIB supports five standard line cards and operates in standard Junos OS. The JNP10008-SF3 SIB supports the 14.4 Tbps line card and operates in Junos OS Evolved systems. See Table 1 for a comparison of the two models.

Number of SIBs required for operation

Base systems require five SIBs; redundant systems require six SIBs

Base systems require three SIBs; partial bandwidth PREM2 systems require four SIBs; and full bandwidth redundant systems require six SIBs. All six SIBs must be installed and active to deliver full throughput rate of the chassis. With JNP10008-SF3, there is no redundancy for switch fabric. Each of the six switch fabric boards provides one-sixth of the full switching fabric bandwidth.

SIBs are hot-removable and hot-insertable field-replaceable units (FRUs). They are not visible from the outside of the router chassis. If you don’t know which switch fabric you have installed, you can use the CLI command show chassis hardware models. Otherwise, you must remove one of the fan trays in order to view the SIBs. For instructions on removing the fan trays, see Remove a PTX10008 Fan Tray. The SIBs are numbered SIB0 to SIB5 from left to right. See Figure 3.
