Auto Configuration Overview
The Auto Configuration feature can automatically update the firmware
image and obtain configuration information when the switch boots. Auto
Configuration begins the automatic download and installation process when
the switch is initialized and no configuration file (startup-config) is found, or
when the switch boots and loads a saved configuration that has Auto
Configuration enabled. Auto Configuration is enabled by default.
The Auto Configuration feature includes two components:
• USB Auto Configuration
•DHCP Auto Install
If no configuration file is found and the Auto Configuration feature is
enabled, the Auto Configuration process begins. If a USB device is connected
to the PowerConnect switch USB port and contains the appropriate file, the
switch uses the USB Auto Configuration feature to update the configuration
or image. If the USB Auto Configuration fails - either because it is disabled,
no USB storage device is present, or no configuration or images files are
present on the USB storage device, the switch uses the DHCP Auto Install
process.
