LAN Subsystem
The Ethernet LAN subsystem is composed of two Gigabit Ethernet ports: One Intel i219LM Physical
Layer Transceiver (PHY) using the PCH CM238 internal MAC and one Intel i210IT Gigabit Ethernet
Controller. These devices provide also legacy 10Base-T and 100Base-TX connectivity. These Ethernet
ports are fed to two RJ45 jacks located in the front panel. Each port includes the following features:
▸
One PCI Express lane per Ethernet port (250MB/s)
▸
1000Base-Tx (Gigabit Ethernet), 100Base-TX (Fast Ethernet) and 10Base-T (Classic Ethernet)
capability.
▸
Half- or full-duplex operation.
▸
IEEE 802.3u, 802.3ab Auto-Negotiation for the fastest available connection.
▸
Jumperless configuration (complete software-configurable).
Two bicoloured LEDs integrated into the dedicated RJ-45 connector in the front panel are used to
signal the LAN link, the LAN connection speed and activity status.
Each device is connected by a single PCI Express lane to the PCH. Their MAC addresses (unique
hardware number) are stored in dedicated FLASH/EEPROM components. The Intel Ethernet software
and drivers for the i219LM and i210IT are available from Intel's World Wide Web site for download.
When managing the board by Intel Active Management Technology (iAMT), the dedicated network
port to do so is accessible by the RJ45 connector GbE1 (the upper port within the front panel).
The i210 controller supports the IEEE 1588 Precision Time Protocol (the one connected to the lower
port within the front panel (GbE2)) and is capable to generate Pulse per Second (PPS) and Pulse per
Minute (PPM) signals that may be routed to the jumper J-GP and the

Serial connector
P1. These signals can be used to trigger events on Mezzanine Side Boards or Peripheral Boards. The
following routing is possible by UEFI/BIOS settings:
▸
Pulse per Second (PPS): J-GP Pin 1 and CompactPCI
®
Pin J3 (signal SATA-SCL)
▸
Pulse per Minute (PPM): CompactPCI
®
Pin H3 (signal SATA-SDO)
