Page 3 - 3 AT8402 User Guide
The main building blocks of the base board are:
• Ethernet Switch
• PCI Express Infrastructure
• SAS/SATA Infrastructure
• Ethernet Switch Controller and Memory
• Synchronous Clock Distribution
• AMC Bays
• IPMI
• RTM Interface
• Power Supply
3.1.1 Ethernet Switch
The main parts of the Ethernet Switch building block is a Broadcom BCM56305 24 port Gigabit
Layer-2/3 Switch and a Broadcom BCM5466R QUAD 10/100/1000BASE-T PHY for the base
and extension fabric interface, AMC and RTM Uplink connectivity. The BCM56305 is managed
via the 32bit/33MHz PCI interface.
A BCM 5466R performs PHY functions for the 10/100/1000BASE-T ports of the RTM (GE1 and
GE2) and the two base interface links.
The ports of the BCM56305 are assigned as follows:
