The main building blocks of the fabric mezzanine are:
• Fabric Switch
•IPMI
• Power Supply
3.2.1 Fabric Switch
The fabric switch is a Broadcom BCM5650x or BCM 5630x 24 port GbE multilayer switch that
can operate in 10/100/1000 Mbps with zero to four 10GbE Uplinks. The BCM5630x integrates
advanced Layer 3 switching features for IPv4 and IPv6 routing. The BCM5650x also includes
enhanced QoS support and jumbo packet line rate switching.
The PPC controls the switch over a 32bit/66MHz PCI Interface.
Fabric Interface (Zone 2)
The Fabric Interface is comprised of 15 channels providing connectivity among up to 16 boards
in a Full Mesh or Star configuration. The Fabric Interface can be used in a variety of ways by
Boards and Backplanes to meet the needs of many applications defined by the PICMG 3.0 Re-
vision 2.0 standard. The pin assignment for the Zone 2 connectors is compliant to the PICMG
3.0 standard.
