PTX3000 Switch Interface Boards

PTX3000 Switch Interface Board Description

The PTX3000 contains nine Switch Interface Boards (SIBs) located at the center of the chassis in the slots labeled SIB0 through SIB8 (left to right). SIBs are hot-insertable and hot-removable.

SIBs create the switch fabric for the PTX3000.

Note:

FPC-SFF-PTX-T FPCs are not supported in a PTX3000 with SIB3-SFF-PTX SIBs.

Note:

Third-generation FPCs (FPC3-SFF-PTX) are supported only in a PTX3000 with SIB3-SFF-PTX SIBs. Third-generation FPCs and FPC-SFF-PTX-P1-A first-generation FPCs can interoperate with each other in the same system.

SIBs Supported

The PTX3000 supports the SIBs listed in Table 1.

ONLINE/OFFLINE button

Each SIB consists of the following components:

  • Switch fabric ASICs

  • High-speed links to each FPC

  • SIB ONLINE/OFFLINE button, located on the SIB faceplate

  • Three LEDs located on the SIB faceplate that display the status of the SIB
