FCC, and then passes over the fabric cables again to the S3 stage in the destination LCC. The following figure
shows a simplified view between the LCC and the FCC.

LCC
In a back-to-back configuration, each LCC uses six Universal Fabric Cards (UFCs) with 16 CXP (in 1T mode)
or CXP2 (in 2T mode) modules each.
In a multi-chassis configuration, the LCC uses either six S13 multi-chassis (MC) fabric cards with 16 CXP
modules each that connect to the S2 fabric cards on the FCC (for 1T mode), or six Universal Fabric Cards
(UFCs) with 16 CXP2 modules each that connect to the 2nd generation S2 fabric cards on the FCC (for 2T
mode).
The planes do not interconnect with each other but operate independently. Because there are a total of six
fabric cards in the LCC, the fabric is referred to as having six planes. For example: Slot 0 in LCC0, LCC1,
and so forth are all part of plane 0.
