Enabling or disabling OS to iDRAC Pass-through using web interface

To enable OS to iDRAC Pass-through using Web interface:

1. Go to Overview → iDRAC Settings → Network → OS to iDRAC Pass-through.

The OS to iDRAC Pass-through page is displayed.

2. Select any of the following options to enable OS to iDRAC pass-through:

• LOM — The OS to iDRAC pass-through link between the iDRAC and the host operating system is established through the

LOM or NDC.

• USB NIC — The OS to iDRAC pass-through link between the iDRAC and the host operating system is established through

the internal USB bus.

To disable this feature, select Disabled.

3. If you select LOM as the pass-through configuration, and if the server is connected using dedicated mode, enter the IPv4

address of the operating system.

NOTE: If the server is connected in shared LOM mode, then the OS IP Address field is disabled.

4. If you select USB NIC as the pass-through configuration, enter the IP address of the USB NIC.

The default value is 169.254.0.1. It is recommended to use the default IP address. However, if this IP address conflicts with an

IP address of other interfaces of the host system or the local network, you must change it.

Do not enter 169.254.0.3 and 169.254.0.4 IPs. These IPs are reserved for the USB NIC port on the front panel when a A/A

cable is used.

5. Click Apply to apply the settings.

6. Click Test Network Configuration to check if the IP is accessible and the link is established between the iDRAC and the host

operating system.
