Hardware Overview
The Sun Dual Gigabit Ethernet and Dual SCSI/P adapter provides two Ultra2 SCSI
and two gigabit Ethernet interfaces. The half-size card has a high performance PCI
host interface with two UTP RJ-45 connectors for 10/100/1000 Mbps Ethernet and a
dual SCSI connector for 80 MBytes/sec SCSI interfaces.
The adapter provides attachment to gigabit Ethernet LANs as well as connectivity to
peripheral devices that require the Ultra2 SCSI interface.
Each of the two
Ethernet
channels provides 10BASE-T, 100BASE-TX, or 1000BASE-
T networking interfaces. The device driver automatically sets the link speed to 10,
100, or 1000 Mbps and conforms to the IEEE 802.3 Ethernet standard. The single
MAC/PHY chip provides the PCI interface and medium access control (MAC)
functions. The local transceiver, which connects to an RJ-45 connector, provides the
physical-layer functions.
The local transceiver is capable of all the operating speeds and modes listed below:
■
1000 Mbps, full-duplex
■
100 Mbps, full-duplex
■
100 Mbps, half-duplex
■
10 Mbps, full-duplex
