LAN Subsystem

The Intel 82562ET (with the Intel 82801DB ICH4) provides a Fast PCI LAN subsystem providing
both 10Base-T and 100Base-TX connectivity. The Intel 82562ET provides the following
functions:
•
Basic 10/100 Ethernet LAN connectivity
•
Supports RJ-45 connector with status indicator LEDs
•
Programmable transit threshold
•
Configurable EEPROM that contains the MAC address

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.

Hi-Speed USB 2.0 Support

✏
NOTE
Computer systems that have an unshielded cable attached to a USB port might not meet FCC
Class B requirements, even if no device or a low-speed USB device is attached to the cable. Use a
shielded cable that meets the requirements for a full-speed USB device.
This desktop board supports up to six USB 2.0 ports via ICH4; four ports routed to the back panel
and two routed to a USB front panel header. The box contents include a two port USB adapter that
connects to the front panel header and mounts to an empty chassis slot (see page 35 for instructions
on how the install the USB 2.0 adapter). USB 2.0 ports are backward compatible with USB 1.1
devices. USB 1.1 devices will function normally at USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer
rates. Disabling Hi-Speed USB in BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may
be required to accommodate operating systems that do not support USB 2.0.
