[c-nsp] High temperatures on cisco 6504-E chassis

[Church, Charles]

How long ago were the switches installed?  Is it possible there is an
accumulation of dust on the module/ASICs?

Hi Robert,

I didn't read anything about this but if i look at some others chassis 
like a 6509 the in- and outlet temps are higher but the asic temps are 
31C. Could it be the fan-tray of a 6504-e isn't powerfull enough to cool

the chassis?
Thanks,

Koen
