Cisco CRS-16-FC/S IPUCAC3BAA 800-18560-08 CRS-1 Series 16 Slots Fabric Card / Single Cisco CRS-16-FC/S
The switch fabric is the core of the Cisco CRS routing system. The Cisco CRS routing system fabric is implemented through multiple redundant switch fabric cards (SFCs) installed in the chassis. The switch fabric uses a cell-switched, buffered, three-stage Benes switch fabric architecture. The switch fabric receives user data from a modular services card (MSC) or Forwarding Processing card (FP) and performs the switching necessary to route the data to the appropriate egress MSC or FP.
