Dell Z9100-ON - 7 Fans; Components

Fans
The Z9100–ON comes from the factory with two PSUs and ve fan modules installed in the chassis. The fan modules and the power
supplies, which have integrated fans, are hot-swappable.
In addition to the power supply modules, you can order and install fan modules separately.
The Z9100-ON supports two airow direction options. Do not mix airow types in a chassis; you can use only a single airow direction in a
chassis. All fans and PSUs in a conguration must be in the same airow direction.
• Normal—airow is from the I/O panel to the PSU.
• Reversed—airow is from the PSU to the I/O panel.
Environmental factors can decrease the amount of time required between fan replacements. Check the environmental factors regularly. An
increase in temperature and particulate matter in the air might aect 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.
