3.2.3 USB and LAN
To save space USB and LAN connectors are provided in the form of combo connectors. These either
comprise two USB connectors or two USB connectors and one LAN connector. This way all board
variants provide four external USB channels.
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 board comes in different variants and LAN connectors are one area in which the variants differ. One
variant has two LAN connectors, the first (P1501) is 10/100 LAN and the second (P1502) is 10/100/1000
LAN. There are also two board variants with only a single LAN connector (P1501, P1502 is 2xUSB in this
case). One of these variants has 10/100 LAN, the other has 10/100/1000 LAN.
The 10/100 LAN connector supports 10BaseT and 100BaseT compatible net components with automatic
bandwidth selection. It also offers auto-cross and auto-negate functionality. The controller chip is the Intel
82562. PXE and RPL functions are also supported.
The 10/100/1000 LAN connector supports 10BaseT, 100BaseT and 1000BaseT compatible net
components with automatic bandwidth selection. It does not offer auto-cross and auto-negate
functionality. The controller chip is the Intel 82573. PXE and RPL functions are not supported.
