I run automatic upgrade on my EX4100 and when I look at the dashboard is say in the firmware is 5.18.117. Does this mean that I am running 0S5 presently. and is there anything else I need to do. The instruction are unclear. get rid of all the read this first that should be a separate section. I still never found the download files.
