Disabling the USB in-band interface Important: If you disable the USB in-band interface, you cannot perform an in-band update of the IMM firmware, server firmware, and DSA firmware by using the Linux or Windows flash utilities. If the USB in-band interface is disabled, use the Firmware Update option on the IMM Web interface to update the firmware. For more information, see "Updating firmware" on page 67. If you disable the USB in-band interface, also disable the watchdog timeouts to prevent the server from restarting unexpectedly. For more information, see "Setting server timeouts" on page 16. The USB in-band interface, or LAN over USB, is used for in-band communications to the IMM. To prevent any application that is running on the server from requesting the IMM to perform tasks, you must disable the USB in-band interface. For more information about LAN over USB, see Chapter 6, "LAN over USB," on page 71. To disable the USB in-band interface, complete the following steps: 1. Log in to the IMM on which you want to disable the USB device driver interface. For more information, see Chapter 2, "Opening and using the IMM Web interface," on page 9. 2. In the navigation pane, click System Settings and scroll down to the Miscellaneous area. 3. Select the Do not allow commands on USB interface check box to disable the USB in-band interface. Selecting this option does not affect the USB remote presence functions (for example, keyboard, mouse, and mass storage). When you disable the USB in-band interface, the in-band systems-management applications such as the Advanced Settings Utility (ASU) and firmware update package utilities might not work. Note: The ASU works with a disabled USB in-band interface if an IPMI device driver is installed. If you try to use systems-management applications while the in-band interface is disabled, they might not work. 4. Click Save. To enable the USB device driver interface after it has been disabled, clear the Do not allow commands on USB interface check box and click Save. Notes: 1. The USB in-band interface is also called "LAN over USB" and is described in more detail in Chapter 6, "LAN over USB," on page 71. 2. When you attempt a network installation of some Linux distributions, the installation might fail if the IMM USB in-band interface is enabled. For more information, see http://rhn.redhat.com/errata/RHBA-2009-0127.html. 3. If you are performing a network installation that does not contain the update on the Red Hat Web site described in the preceding note 2, you must disable the USB in-band interface before you perform the installation and enable it after the installation is complete. 4. For information about the configuration of the LAN over USB interface, see "Configuring the LAN over USB interface manually" on page 71. Chapter 3. Configuring the IMM 19
