Install Guide
Fans
The Z9100–ON comes from the factory with two PSUs and ve fan modules installed in the switch. The fan modules and PSUs, 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 requires a minimum of four
running fans.
The Z9100-ON supports two airow direction options. Do not mix airow types in a switch; you can use only a single airow direction in a
switch. All fans and PSUs in a conguration must be in the same airow direction.
• Normal—airow is from the I/O side to the PSU side.
• Reversed—airow is from the PSU to the I/O side.
Environmental factors can decrease the amount of time needed between fan replacements. Check the environmental factors regularly. An
increase in temperature and particulate matter in the air might aect 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.
