2.8Ethernet Connection

2.8.1PCI Express (PCI-E) Ethernet

The PCI-E implemented on the Intel® ICH6 southbridge chipset connects directly to two Gigabit Ethernet (GbE) controllers (Marvell Yukon 88E8053) with a concurrent bandwidth of 5Gb/s (2.5Gb/s in each direction).

2.8.2 GbE Ethernet

The two Gigabit Ethernet (GbE) controllers (Marvell Yukon 88E8053) on the 3301690 CPU board connect to two 10/100/1000Mb/s Ethernet RJ-45 LAN ports on the rear panel. The GbE controllers come with the following features:
