Removing Mitel ASU II on 3300 Controller

[Twinsen]

Hey Guys,

I have the ASU II device hooked into our Mitel 3300 controller and I need to remove the device as we no longer need it.

The issue is, when I remove the device I get a warning event within the Mitel controller stating that:

"Catagory Name = Lines
Alarm level =  Minor
Total =   166 
Unavailable %14
Minor Threshhold =  >0
Major Threshold =   20
Critical Threshold =  100 "

Does anyone know how I can remove the enteries for the ASU on the Mitel 3300 Controller and stop these warnings happening with the ASU II device removed?

I can see the device in Analog Services Unit, yet when I try and clear(with the unit powered down) it it states "Device is not deassigned"...
When I try and remove it when it is powered on it states "Device is not man-busied "

I'm suck with where I need to change settings to safely remove the device and stop the warning messages.

Thanks all :->

You need to delete anything that is programmed on the ASU, then take out the card and ASU programming in the system.

Sorry to bring up an old post

Did you ever get a solution to this as I have the exact same problem. however all analogue devices are removed from the ASU yet it still gives me the error "Device is not deassigned" when I try to delete the ASU.

You need to busy out the analogue trunks then remove all associated programming for the trunks and extensions.
