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 an 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.
