DRAC 5 Overview 19
The 50-pin management cable is the main interface to the DRAC that provides connectivity to USB,
serial, video, and an inter-integrated circuit (I2C) bus. The 44-pin MII cable connects the DRAC NIC to
the system’s motherboard. The RJ-45 connector connects the DRAC NIC to an out-of-band connection
when the DRAC 5 is configured in Dedicated NIC mode.
Using the management and MII cables, you can configure your DRAC in three separate modes,
depending on your needs. See "DRAC Modes" in "Using the RACADM Command Line Interface" for
more information.
