Fabric Channel Interface

The ATCA-F140 uses Broadcom BCM56846 switch device for the fabric channel interface.
It is a high-performance 640Gbps network switch with 18 integrated warpCores (16 active).
Each warpCore has four integrated 10G SerDes allowing native support of one 40GbE or
four 10GbE ports. On the ATCA-F140, the BCM56846 is used to provide sixteen (16) 40G
ports and four 1G ports.
12 of the 40Gbps ports are routed to the backplane switch fabric support of a 14-slot
chassis. Two 40Gbps uplink interfaces from the switch are routed to the Zone 3 connectors
for use by an RTM. Two other 40Gbps uplink ports are routed to BCM84740PHYs to
provide two QSFP+ uplinks on the front panel. The P2020 service processor communicates
with the BCM56846 through the PCI Express interface to initialize and manage the switch.
Two 1G-SGMII ports are routed to the backplane for switch fabric support of the two extra
slots in a 16-slot chassis, or optionally, to the TopSync device and Fabric Channel 1. One
1G-SerDes port is routed to AMC port 1. One 1G-SGMII port is routed to update channels
3 and 4 to form a fabric switch-to-AMC cross-connect with the other switch blade across
the backplane.
