Fans

The S6100–ON comes from the factory with two PSUs and four fan module installed in the chassis. The fan module and power supply,

which have integrated fans, are hot-swappable.

In addition to the power supply modules, you can order and install fan modules separately.

The S6100-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. If the airow directions are mismatched, the S6100-ON issues an alarm. You must correct the mismatched airow direction.

The fans and PSUs are color coded for air ow direction. Red is normal air ow and blue is reverse air ow.

• Normal—airow is from the I/O panel to the PSU—red.

• Reversed—airow is from the PSU to the I/O panel—blue.

All fans and PSUs in a conguration must be in the same airow direction.

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.
