F5 wont boot after adding HF on 11.4.1

Hi Fawkes, There was a few suggestions from F5, but in the end it was returned to F5. I think given time I could have resolved it, but we had time issues so it was returned. The issues is a an issue where the AOM settings are not in sync with the rest of the F5 F5 recommended to turn off the box for 10 mins and then turn it on again, it was a quick response, so I guessed they had seen it before, but in my case it made no differance and did not resolve it Give it a try, turn it off for 10 mins and then see if it will boot after that. What does you front screen say, mine just said "F5 incorporated" and never went past that. Let me know how you get on, as I still have to do this on another box, but have avoided it after this issue Graham
