Users Guide

● 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: If you launch iDRAC Service Module while USB NIC is in disabled state, the iDRAC Service Module changes the USB
NIC IP address to 169.254.0.1.
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.
NOTE: iDRAC may not be accessible from the host server using LOM-Passthrough when NIC teaming is enabled. Then,
iDRAC can be accessed from the host server OS using the iDRAC USB NIC or through the external network, via the iDRAC
dedicated NIC.
