Installing Route Processor Cards, Fabric Cards, and Line Cards

About Fabric Cards

The chassis supports four fabric cards (FCs), which are agnostic cross-connects based on a flexible cell
switching architecture used in a Clos configuration. FCs are called agnostic because they will switch a cell
with no knowledge of whether they belong to OTN switching or Ethernet switching. Each fabric card in NCS
4016 hosts three fabric devices, which are equally distributed across the 16 line cards. whereas in NCS 4009,
the fabric card hosts a fabric device.
FCs provide the switch fabric for the routing system and perform the cross-connect function of the routing
system, connecting every LC to each other. The switch fabric receives ingress user data from one LC slot and
performs the switching necessary to route the data to the appropriate egress LC slot.
The chassis supports the 200G and 400G fabric cards. The 400G fabric card enables 400G traffic using the
400G line card. The datapath link speed of 400G FC-LC is twice that of the 200G FC-LC. The 200G and the
400G fabric cards support a single chassis only in NCS 4009.

An Auxiliary Fan Tray (Cisco PID NCS4009-FAN-FC) is attached to the NCS4009-FC2F-S fabric card in
the front. The Auxiliary Fan Tray (AFT) and the fan tray present in the front of the chassis (behind the craft
panel), provide cooling for the chassis components.
Caution
The four NCS4009-FC2F-S fabric cards and the four AFTs should be present in the chassis at all times except
during the replacement of the FC or AFT.
The AFT remains attached to the fabric card at all times. The only time when the AFT can be detached from
the fabric card is when either the fabric card or the AFT needs to be replaced. Power is supplied to the AFT
through the NCS4009-FC2F-S fabric card.
