The main parts of the Ethernet Switch building block is a Broadcom BCM56502 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 BCM56502 is managed via the 32bit/33MHz PCI interface.
A BCM 5466R performs PHY functions for the 10/100/1000BASE-T ports of the Unit Computer and the two base
interface links.
The ports of the BCM56502 are assigned as follows:
