LAN Subsystem (Optional)
The optional Intel 82562ET (in conjunction with the Intel 82801BA ICH2) provides a Fast
Ethernet PCI LAN subsystem providing both 10Base-T and 100Base-TX connectivity.
Features include:
•
32-bit, 33-MHz direct bus mastering on the PCI bus
•
Shared memory structure in the host memory that copies data directly to/from host memory
•
A single RJ-45 connector with connection and activity status LEDs
•
Jumperless configuration; the LAN subsystem is completely software configurable
LAN Subsystem Software
For Intel 82562ET Fast Ethernet PCI LAN software and drivers, refer to the D850MD and
D850MV link on Intel

RJ-45 LAN Connector LEDs
Two LEDs are built into the RJ-45 LAN connector.
Table 3 describes the LED states when the
board is powered up and the LAN subsystem is operating.
