The PCIe lane from the Intel® ICH7 chipset of the PPC-37xx-N270 is interfaced to the
Realtek RTL8111E PCIe gigabit Ethernet (GbE) controllers. The RTL8111E controllers
are then connected directly to the RJ-45 connectors on the bottom panel and provides
external GbE connectivity. Some of the RTL8111E controller features are listed below:
Integrated 10/100/1000 transceiver
Supports PCI Express™ 1.1
Fully compliant with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab
Supports IEEE 802.1P Layer 2 Priority Encoding
Supports IEEE 802.1Q VLAN tagging
Serial EEPROM
Transmit/Receive on-chip buffer support
2.4.3 External USB Connectors
There are two USB 2.0 connectors on the bottom panel of the PPC-37xx-N270 (the
PPC-37xxB-N270 series has four USB connectors). Both USB 2.0 connectors are
interfaced directly to the USB controllers on the ICH7-M southbridge. These USB
connectors are fully compliant with USB specification Revision 2.0 and USB specification
Revision 1.1 and can be interfaced to both USB 1.1 and USB 2.0 compliant devices.
