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:
