About Sun PCIe Dual-Port GbE UTP EM

The Sun PCI Express (PCIe) Dual-Port Gigabit Ethernet (GbE) UTP ExpressModule (EM) is a dual-port GbE copper-based PCIe adapter. The GbE UTP EM can be configured to operate in 10/100/1000-Mbps Ethernet networks. At 10 or 100 Mbps, the GbE EM can be set to either half-duplex or full-duplex operation. At 1000 Mbps, the GbE UTP EM must operate at full-duplex.

Feature Overview

The GbE UTP EM is based on the Intel 82571EB 10/100/1000-Mbps Ethernet controller and supports the following features:

  • Single-wide PCIe EM form factor requirements

  • Two 1-Gbps Ethernet ports

  • Two single RJ-45 connectors

  • Link and Activity LEDs for each port

  • I/O Diag, FCode, BootNet, and POST resources

  • EEPROM, AT25128A, 16-Kbyte, connected to 182571 SPI (serial EEPROM) bus

  • Thermal monitoring, National LM75 connected to the serial SMBus

  • Hot-plug operations

  • DC-DC from 12V to 3.3V, 1.8V and 1.2V (1.0V) support

  • 1.2V, 1.8V, and 3.3V readout and fine adjustment, SMM150, connected to the serial SMBus

Channel Performance

Each of the two channels provides 10BASE-T, 100BASE-TX, or 1000BASE-T networking interfaces. The device driver automatically sets the link speed to 10/100/1000-Mbps and conforms to the IEEE 802.3 Ethernet standard. The single MAC/PHY chip provides the PCIe interface and MAC (media access control) functions.

The drivers are capable of all the following operating speeds and modes:

  • 1000 Mbps, full-duplex

  • 100 Mbps, full-duplex

  • 100 Mbps, half-duplex

  • 10 Mbps, full-duplex

  • 10 Mbps, half-duplex

The GbE UTP EM performs autonegotiation with the remote end of the link (the link partner) to select a common mode of operation.
