Hi Charles, (i'm a colleague) , we've just installed them, fresh new suite, fresh new cisco's. There's also no production traffic on it yet, just testing at this moment. I think they've been up for little over a month.
There's no blocking in airflow, also seems that inlet temps that the cisco is reporting, is not the temp we see when using a temp reader in front of the chassis (10C difference) Maybe it's the fact that these are sup720-3cxl-10ge , with X2 modules installed (which also seem to get hot, 41C), and this packed in a small chassis.... Just looking for answers from somebody who has similar experience with the 6504 chassis.
