Users Guide

• In shared mode, the host operating system's IP address is used.
• In dedicated mode, you must provide a valid IP address of the host operating system. If more than
one LOM is active, enter the first LOM’s IP address.
If the OS to iDRAC Pass-through feature does not work after it is enabled, ensure that you check the
following:
• The iDRAC dedicated NIC cable is connected properly.
• At least one LOM is active.
NOTE: It is recommended to use the default IP address. Ensure that the IP address of the USB NIC
interface is not in the same network subnet as the iDRAC or host OS IP addresses. If this IP address
conflicts with an IP address of other interfaces of the host system or the local network, you must
change it.
NOTE: Do not use 169.254.0.3 and 169.254.0.4 IP addresses. These IP addresses are reserved for
the USB NIC port on the front panel when a A/A cable is used.
