we have a C6509-E with interesting temperature issue. The EARL chip on

We have swapped the chassis, fan, module and sup and still have the
same issue. The interesting part is when we moved the card in module 1
into module 2 - no temperature issue.
From this I deduce that we have some kind of air flow issues, as
module 1 has worse air flow than module 2. Does somebody have some
nice doc that describes the C6509-E air flow? Or maybe a recomendation
about the room air conditioning, or air flow in the room.
The 6509-E has right-to-left airflow like the non-E version. Make sure
nothing is blocking the intake vents on the right side of the chassis and
that nothing in the cabinet/rack to the right (if there is one) is
exhausting hot air toward the 6509-E.
I have several 6509s (E and non-E) in production and have had no
temperature issues with them, aside from one that was located in a dirty
area and the intake vents got fouled. Once the obstruction was cleared,
the temperature alarms went away.
