NOTE: Both slots must have operating fan units to run the system. If a module is not installed in each slot (either as part of the PSU or as an independent fan module), the system will shut down in 1 minute. The S55 and the S60 both support two airflow direction options. Only a single direction can be used in a chassis; do not mix fan flow types in a chassis. The system will shutdown in 1 minute, if the airflow directions are mismatched. • Normal is airflow from I/O panel to power supply • Reversed is airflow from power supply to I/O panel There are environmental factors that could decrease the amount of time required between air filter replacements. Check these environmental factors regularly. Any unusual environmental circumstance at the site that causes an increase in temperature and/or particulate matter in the air might affect performance (for example, new equipment installation).
