Just had the 200/20 fibrex installed and would like to backup the configuration before changing name and passwords. Below is the information in regards backing up from the Vodafone website.

However once I get into the "Device Management" page I'm unable to find the "Expand the backup up or restore setting section".

This is from the Vodafone website -

Backup your Vodafone wireless modem configuration

Browse to your modem's admin page and log in with the following details: Default username Admin. Default password VF-NZhg659 (case sensitive) or. ...
Click the Maintain tab.
Click Device Management.
Expand the Back Up or Restore Settings section.
Select Back Up.
