• If the USB drive contains a setup file, but that setup file does not include a
line that can be used for the current device, the DHCP client is able to
trigger the Auto-Update process from TFTP (because the USB process
never started at all).
Automatic DHCP IP Address Assignment
The user can manually define a DHCP interface in the IPv4 Addressing page
through which the IP address is received from the DHCP server.
If the user does not do this, the switch automatically creates a DHCP
interface on the default VLAN.
Before Auto-Update/Configuration from a USB drive can be performed, the
following steps must be performed:
1. Enable Auto-Update/Configuration in the
Auto Update of
Configuration/Image File
page.
2. (Optional) Create a line in the setup file for this device containing the
required options and load it on the USB key.
3. Load configuration/image files on the USB key as required.
4. Insert the USB key in the USB drive and reboot the device.
When Auto-Update is initiated from a USB drive, the following steps are
performed:
1. Locate the correct setup file
— The USB drive is searched for a setup file.
One of the following can occur:
– Setup file is not found—The root folder of the USB is searched for an
image files (with
.ros extension).
• The image file with the most recent version is loaded into the
image file if the versions are different.
• If a new image file was loaded, the device is rebooted.
• The USB drive is searched for a configuration file (
.text
extension). If there is more than one configuration file, the file
named
powerconnect.text is loaded (if it is not found the process
is stopped).
– One or more setup files are found—If a single setup file is found, it is
used; if several files are found, the file
powerconnect.setup is used. If
no setup file with this name is found, the process is stopped.
