376 Auto Image and Configuration Update
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. 
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 
multiple *.stk files are present, the switch uses the image with the highest 
(most recent) version. Finally, if no *.setup, *.text, or *.stk files are found, the 
switch proceeds to the DHCP Auto Configuration process.
NOTE: Neither USB Configuration nor Auto Install is invoked if a valid 
configuration file is on the switch.
