9.8.0.0.203 is pretty old and one of the first firmware to ship on the R700. 9.8.0.0.373 came after that, then 9.8.1.0.99/101, and then 9.8.2.0.15, which is the recommended version and the latest standalone version.
For ZD managed networks, 9.9.0.0.205 is currently out, but cannot be used standalone.
