What Is USB Auto Configuration? You can use the USB Auto Configuration feature to configure or upgrade one or more switches that have not been previously configured, such as when you deploy new switches. Before you deploy the switch, you perform the following steps: 1 Create a text file that contains IP addresses (and/or MAC addresses) and file names that are parsed and used by this feature. The MAC address used to identify the switch is the MAC address of the out-of-band interface (see "Switch Addresses" on page 97 for further information). 2 Copied the file onto a USB device. 3 Insert the USB device into the front-panel USB port on the PowerConnect switch. When the Auto Configuration process starts and a factory default or empty configuration file is present on the switch, the feature automatically searches a plugged-in USB device for information. What Files Does USB Auto Configuration Use? The USB Auto Configuration feature uses the following file types: • *.setup file for initial switch configuration • *.text file for configuration information • *.stk file for software image installation The Auto Configuration file searches the USB device for a file with a *.setup extension. If only one .setup file is present, the switch uses the file. When multiple *.setup files are present, the switch uses only the powerconnnect.setup file. If no powerconnect.setup file is available, the switch checks for a file with a *.text configuration file and a *.stk image file. If multiple .text files exist, the switch uses the powerconnect.text file. If 334 Auto Image and Configuration Update
