Intel® FM2112 24-Port 10G/1G Ethernet Switch Chip Data Sheet

1.2.1

Advanced TCA Chassis Base Fabric Switch

The FM2112's high level of integration (high port count) makes it a

great fit for the Advanced TCA chassis (including the 14-slot, 19”-rack

version and the 16-slot, 23”-rack version, as well as the smaller

variants). With 8 10G ports and 16 2.5/1G ports, the device

complements the FM2112 on the fabric boards and supports the ATCA-

defined dual star base fabric.

In this application, two slots in the chassis are populated with switch

fabric cards that provide main fabric and base fabric connections to all

other cards in the chassis. The 16 1G Ethernet base interfaces on these

hub boards connect to the Shelf Management Controller, the other hub

board and the 14 node boards.

Key Capabilities

• 10G inter-switch links to data fabric switch (optional)

• Up to 16 1G Ethernet ports for connection to the 1G Ethernet base fabric

• Fail-over redundancy from one switch element to the other, using a method of

polling status information between the two switch elements, and rapidly switching

traffic from one element to the other.

Stackable Switch

In this application, the FM2112 serves as the core of a stackable switch

implemented in a 1U form factor, providing a low cost point of entry

and subsequent scalability. The non-blocking, low latency
