6 Fans The S6000 comes from the factory with two PSUs and three fan modules installed in the switch (see Figure 6-1). The S6000 has SKUs that support the following configurations. Installation of the fans is done as part of the factory install based on SKU type. • AC PSU with fan airflow from I/O to PSU • AC PSU with fan airflow from PSU to I/O • DC PSU with fan airflow from I/O to PSU • DC PSU with fan airflow from PSU to I/O All fans and PSUs in a configuration must be in the same airflow direction. Should a mixed airflow configuration happen, the software notifies you of the invalid configuration. The S6000 supports three fan modules with airflow directions from the I/O to the utility or the utility to the I/O. 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 cooling fans in order to accurately determine replacement intervals.

The S6000 comes from the factory with two PSUs and three fan modules installed in the switch (see
Figure 6-1
). The S6000 has SKUs that support the following configurations. Installation of the fans is
done as part of the factory install based on SKU type.
•
AC PSU with fan airflow from I/O to PSU
•
AC PSU with fan airflow from PSU to I/O
•
DC PSU with fan airflow from I/O to PSU
•

All fans and PSUs in a configuration must be in the same airflow direction. Should a mixed airflow
configuration happen, the software notifies you of the invalid configuration.
The S6000 supports three fan modules with airflow directions from the I/O to the utility or the utility to
the
I/O.
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 cooling fans in order to accurately determine replacement intervals.
