4.9 USB 5 and 6, LAN2

USB channels 5 and 6 are combined with LAN2 into one standard IDC socket connector with a spacing

onf 2.54 mm. All required settings can be accomplished in BIOS setup.

The USB channels support USB 2.0. You may note that the setting of USB keyboard or USB mouse

support in the BIOS-setup is only necessary and advisable, if the OS offers no USB-support. BIOS-setup

can be changed with a USB keyboard without enabling USB keyboard support. Running Windows with

these features enabled may lead to significant performance or functionality limitations.

Every USB interface provides up to 500 mA current and is protected by an electronical fuse.

The LAN-interface supports 10BaseT, 100BaseT, and 1000BaseT compatible net components with

automatic bandwidth selection. Additional signals are provided for status LEDs.

NOTE

LAN LEDs are most commonly connected in the following way: Pins 9 and 20 are connected to a

conventional LED while pins 10 and 19 are connected to a bi-color LED. The latter indicates "link" and

"link100" each in a different color. In rare cases it can be desirable to have one separate LED for each of

the three signals "active", "link", and "link 100". For this non-standard solution to work you need to add a

330Ohm resistor to the LILED2 line.
