Upgraded MXEIII controller to latest release 9.0. Noticed that AMB only has 2 available ports and when I plug in 10 ASUIIs CIM1 on the mainboard goes off line. Trouble shot all the hardware and all each component works as it should until I plug in the 10th ASU. Has anyone run into this? this is my first 9.0 install so not sure if it is software related.
