Configuring the LAN over USB interface

An IMM2 must be configured to use the LAN over USB interface. The firmware update package or Advanced Settings Utility attempts to perform the setup automatically, if needed. If the automatic setup fails or if you prefer to set up the LAN over USB manually, use one of the following processes.

For more information about LAN over USB configuration on different operating systems, see Introducing UEFI-Compliant Firmware on Lenovo System x and BladeCenter Servers.

  • Installing the LAN over USB Windows device driver
    When you install a Windows operating system, there will be an unknown RNDIS device in the Device Manager. Lenovo provides a Windows INF file that identifies this device. The signed version of the INF file is included in all of the Windows versions of the IMM2, UEFI, and DSA update packages. Complete the following steps to install ibm_rndis_server_os.inf.
  • Installing the LAN over USB Linux device driver
    Versions of Linux since RHEL5 Update 3 and SLES10 Service Pack 2 support the LAN over USB interface by default. This interface is detected and displayed during the installation of these operating systems.
