Dell S4128F-ON Series User Manual

Fans
The S4100–ON Series (S4128F-ON and S4148F-ON) switch comes from the factory with two PSUs and four fan modules installed in the
chassis. The fan modules and the power supplies are hot-swappable.
NOTE: To run the switch, all slots must have operating fan units. If you do not install a module in each slot, the switch shuts down
in one minute.
In addition to the power supply modules, you can order and install fan modules separately.
NOTE: The S4100–ON Series switch supports two airow direction options—normal and reverse. All fans and PSUs MUST have
the same airow direction. If you mix the airow direction, to avoid heat damage to the switch components, you must correct the
mixed airow direction .
• Airow is from the I/O panel to the PSU—normal.
• Airow is from the PSU to the I/O panel—reverse.
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.
