PTX5000 Switch Interface Board Description

SIB Slots

The PTX5000 Switch Interface Boards (SIBs) form the switch fabric for the router. Each PTX5000 contains nine SIBs located at the center rear of the chassis in the slots labeled SIB0 through SIB8 (top to bottom). SIBs are hot-insertable and hot-removable.

SIB Function

SIBs create the switch fabric for the PTX5000.

SIBs Supported on the PTX5000

The PTX5000 supports the following SIBs:

  • SIB-I-PTX5008

  • SIB2-I-PTX5K

  • SIB3-I-PTX5K
