Re: internal temperature

from the planning manual - online
http://www.as400.ibm.com/tstudio/planning/environ/temp.htm
olderr manuals had the following
Most server units and devices operate best between 18° C (65° F) and 29° C
(85° F). We recommend an optimal temperature of 24° C (76° F). Check system
requirements for thermal output and temperature ranges to help figure out
your temperature environment
newer stuff (but couldn't find new system requirements-kept taking me to old
pages
REQUIREMENTS    for disk expansion towers for 820 & 830
Operating 10° to 38° C (50° to 100.4° F)
Non-Operating 1° to 60° C (33.8° to 140° F)

quite a diff from 85 to 100?
