On the host system, while installing RHEL 5.9 operating system, the USB NIC pass-through mode is in disabled state. If it is enabled after

the installation is complete, the network interface corresponding to the USB NIC device is not active automatically. You can do any of the

following to make the USB NIC device active:

• Configure the USB NIC interface using Network Manager tool. Navigate to System > Administrator > Network > Devices > New

> Ethernet Connection and select Dell computer corp.iDRAC Virtual NIC USB Device. Click the Activate icon to activate the

device. For more information, see the RHEL 5.9 documentation.

• Create corresponding interface’s config file as ifcfg-ethX in /etc/sysconfig/network-script/ directory. Add the basic

entries DEVICE, BOOTPROTO, HWADDR, ONBOOT. Add TYPE in the ifcfg-ethX file and restart the network services using the

command service network restart.

• Reboot the system.

• 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 the system

is turned on and if the USB NIC is enabled, the USB NIC device is not active automatically. To make it active, check if any ifcfg-

ethX.bak file is available in the /etc/sysconfig/network-script directory for the USB NIC interface. If it is available, rename it

to ifcfg-ethX and then use the ifup ethX command.

Installing VIB file

For 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-check

The output is:

Message: The update completed successfully, but the system needs to be rebooted for the

changes to be effective.

Reboot Required: true

VIBs Installed: Dell_bootbank_iDRAC_USB_NIC_1.0.0-799733X03

3. Reboot the server.

4. At the ESXi prompt, run the command: esxcfg-vmknic –l.
