25SFF server with any drive configuration
Use Table 26 to determine the maximum operating temperature of the 25SFF server with any drive
configuration. A maximum server operating temperature applies if the server contains any options in
its matching hardware option list.
If a single fan fails, the maximum server operating temperature drops by 5°C (41°F) and cannot
exceed 35°C (95°F).
NOTE:
All maximum server operating temperature values are provided on the basis that the fans are
installed as needed and operating correctly. For more information about fan configurations, see the
guidelines in "Installing fans."
