Fans; Components - Dell Z9100-ON Installation Manual

Fans

The Z9100–ON comes from the factory with two PSUs and five fan modules installed in the chassis. The
fan modules and the power supplies, which have integrated fans, are hot-swappable.
NOTE: To run the system, all slots must have operating fan units. If you do not install a module in
each slot (either as part of the PSU or as an independent fan module), the system shuts down in one
minute.
In addition to the power supply modules, you can order and install fan modules separately.
The Z9100-ON supports two airflow direction options. Do not mix airflow types in a chassis; you can use
only a single airflow direction in a chassis. If the airflow directions are mismatched, the Z9100-ON issues
an alarm. You must correct the mismatched airflow direction.
• Normal — airflow is from the I/O panel to the PSU
• Reversed — airflow is from the PSU to the I/O panel
All fans and PSUs in a configuration must be in the same airflow direction.
Environmental factors can decrease the amount of time required between fan replacements. Check the
environmental factors regularly. An increase in temperature and/or particulate matter in the air might
affect performance (for example, new equipment installation).
CAUTION: Check the fans at six-month intervals and replace them as necessary. Regularly
monitor the speeds of the fans to accurately determine replacement intervals.
