I have an Enhanced FlexWan module in an 6506e chassis with SUP 720. The modules in slot 3 & 4 have no power. Thru show mod i see pwr down and diag unknown. I issue power enable mod 3 & 4 still no change. I put them in another 6506 and they show good. Any ideas? These are new cards from another vendor since they are EOS/EOL.
