I had built an AP with a X86 system and a RB 14 card with 2 XR5 cards. It was working well. I added a second RB14 card with a XR2 card and a R52H card. I now notice that customers on the XR5 card consistently reset/lose connestion. How can I confirm that it is because of the new cards, without taking the cards back out? Can I have 2 RB14 cards connected to the same motherboard? Does the XR2 and R52H card draw full power even if they are software disabled? I disabled the XR2 and R52H card and I can still do a frequency scan. I guess that that means the the card are still somewhat working. pls advise. Thanks.
