• Turn off and turn on the system.On systems with RHEL 5.9 operating system, if the USB NIC was disabled and if you turn off the system or vice-versa, when thesystem is turned on and if the USB NIC is enabled, the USB NIC device is not active automatically. To make it active, check if anyifcfg-ethX.bak file is available in the /etc/sysconfig/network-script directory for the USB NIC interface. If it is available, rename it toifcfg-ethX and then use the ifup ethX command.Related linksInstalling VIB fileInstalling VIB fileFor vSphere operating systems, before enabling the USB NIC, you must install the VIB file.To install the VIB file:1. Using Win-SCP, copy the VIB file to /tmp/ folder of the ESX-i host operating system.2. Go to the ESXi prompt and run the following command:esxcli software vib install -v /tmp/ iDRAC_USB_NIC-1.0.0-799733X03.vib --no-sig-checkThe output is:Message: The update completed successfully, but the system needs to be rebooted for thechanges to be effective.Reboot Required: trueVIBs Installed: Dell_bootbank_iDRAC_USB_NIC_1.0.0-799733X03VIBs Removed:VIBs Skipped:3. Reboot the server.4. At the ESXi prompt, run the command: esxcfg-vmknic –l.The output displays the usb0 entry.Enabling or disabling OS to iDRAC Pass-through using web interfaceTo 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 theLOM or NDC.• USB NIC — The OS to iDRAC pass-through link between the iDRAC and the host operating system is established throughthe 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 IPv4address 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 anIP 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/Acable 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 hostoperating system.92
