Configuring USB

Use the information in this topic to control the USB interface used for in-band communication between the server and the IMM2.

Select the USB tab to view or modify IMM2 USB settings. The USB in-band interface, or LAN over USB, is used for in-band communications to the IMM2. Click the Enable Ethernet over USB check box to enable or disable the IMM2 Lan over USB interface.
Important
If you disable the USB in-band interface, you cannot perform an in-band update of the IMM2 firmware, server firmware, and DSA firmware using the Linux or Windows flash utilities. If the USB in-band interface is disabled, use the Firmware Server option under the Server Management tab to update the firmware. If you disable the USB in-band interface, also disable the watchdog timeouts to prevent the server from restarting unexpectedly.

The following illustration shows the USB tab.
