• iDRAC Settings utility (pre-operating system environment)
If the network configuration is changed through iDRAC Web interface, you must wait for at least 10 seconds before enabling OS to iDRAC
Pass-through.
If you are using the XML configuration file through RACADM or WSMAN and if the network settings are changed in this file, then you
must wait for 15 seconds to either enable OS to iDRAC Pass-through feature or set the OS Host IP address.
Before enabling OS to iDRAC Pass-through, make sure that:
• iDRAC is configured to use dedicated NIC or shared mode (that is, NIC selection is assigned to one of the LOMs).
• Host operating system and iDRAC are in the same subnet and same VLAN.
• Host operating system IP address is configured.
• A card that supports OS to iDRAC Pass-through capability is installed.
• You have the Configure privilege.
When you enable this feature:
• 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: 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 an A/A cable is used.
