• 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.
2. Find the line in the setup file relevant to the device—When the correct
setup file is found, it is searched for a line relevant to the device, as
follows:
– The setup file is searched for a line with format A or B in which there
is a match to the device's MAC address. If such line is found, and its
format is valid (the <flag> field is empty), the line is applied.
– If no line for the specific device was found, the setup file is searched
for valid lines with formats C or D. The first line found is applied.
3. Apply the correct line—When the correct line in the setup file is found,
it is applied, as follows:
– If the line contains an IP address and IP mask, the IP address is
configured on the default VLAN.
– If the line contains an image file and its version differs from the
current image file version, the USB image file is loaded and the switch
is rebooted.
– If a new image file was loaded, it is loaded onto all units in the stack.
– If the line contains a configuration file, the configuration file is
appended to running configuration file.
4. Mark the flag in the applied line—When the line is applied (successfully
or not), its flag is set, as follows:
– If the line contains an IP address and IP mask (format C or D), the IP
address is configured on the default VLAN and the line is marked as
"in-use". This ensures that the line is not used for another device.
– If the line was not applied successfully, for one of the following
reasons, the line is marked as "invalid" and a SYSLOG message is sent.
