Table 7 describes the LED states when the board is powered up and the 10/100 Mbits/sec LAN
subsystem is operating.
Table 7. LAN Connector LED States
LED Color LED State Condition
Off 10 Mbits/sec data rate is selected. Green
On 100 Mbits/sec data rate is selected.
Off LAN link is not established.
On (steady state) LAN link is established.
Yellow
On (brighter and pulsing) The computer is communicating with another computer on
the LAN.
1.11.2 Gigabit LAN Subsystem
The Gigabit (10/100/1000 Mbits/sec) LAN subsystem includes the MCH (with its CSA interface),
the Intel 82547EI PLC, and an RJ-45 LAN connector with integrated status LEDs.
1.11.2.1 Intel
®
82547EI Platform LAN Connect Device
Intel 82547EI provides the following functions:
• Basic 10/100/1000 Ethernet LAN connectivity
• Communication Streaming Architecture (CSA) port provides higher throughput and lower
latencies than the Intel 82562EZ device, resulting in up to 30% higher bus throughput (up to
wirespeed)
• Full device driver compatibility
• Programmable transit threshold
• Configuration EEPROM that contains the MAC address
1.11.2.2 RJ-45 LAN Connector with Integrated LEDs
Two LEDs are built into the RJ-45 LAN connector (as shown in Figure 15). Table 8 describes the
LED states when the board is powered up and the 10/100/1000 Mbits/sec LAN subsystem is
operating.
