Accessing the IMM2

Use this information to access the IMM2 in the upper or lower compute node remotely using the command-line interface, serial over LAN, or web interface; or locally through the LAN over USB interface.

The integrated management module II (IMM2) is a second generation hardware control device that provides enhanced systems-management processor functions, video controller, and remote presence function in a single chip. The upper and lower compute nodes operate independently and each has its own IMM2.

For more information about the IMM2, see the Integrated Management Module II User’s Guide (you might need to register to access this content).

  • Accessing the IMM2 remotely
    This topic provides information about the remote systems-management capabilities.
  • Accessing the IMM2 using the LAN over USB interface
    Unlike a baseboard management controller, the IMM2 does not require IPMI device drivers or USB daemons for in-band IMM2 communication. Instead, a LAN over USB interface enables in-band communication to the IMM2; the IMM2 hardware on the system board presents an internal Ethernet interface from the IMM2 to the operating system. LAN over USB is also called the USB in-band interface in the IMM2 web interface.
