    Hello I'am Mario reyes from Mexico City, 
    
    In the next two weeks we will to install a ALPHASERVER 8400 5/440 in
    BANCO INTERNACIONAl, this customer is a Bank in constant growing, the
    SITE will be in TOLUCA, MExico STATE this place is at 2800 meters over
    the level sea (ALTITUDE). In the SITE PREP of this server I see that the max
    altitude is 2.4 Km.
    
    	Which could be implicationa with this customer restriction in the
    behaviour of the hardware in the server 8400?

    It involves cooling the machine properly. What is required, is for 
    somebody to supply or calculate the max Ambient temp at that elevation.
    What the result will be is that the current spec for a class-A 
    computer room of 28 C will be lowered to insure adequate cooling. 
    In reality it is probably not an issue since the 8200 can operate
    in a class-B 35 C max temp and typically the CPU chips are the parts
    needing the most cooling. Check to be certain
