Fan Units (sFUs)
The 4700 chassis is pre-assembled at the factory with the fan units installed at the front of the
chassis. The fan units are hot-swappable modules.
At the system startup, the fan speed is set to turbo mode until adequate temperature is reached.
The fan speed is then set to normal mode.
The 4700 hosts a vertical fan unit (sFU-40V) and a horizontal fan unit (sFU-40H). When
replacing one of the 4700 fan units, the other takes over and changes to turbo mode, to ensure
proper system ventilation.
The 4700 fan units can be replaced within 5 minutes without interruption to the operation of
the chassis and without disconnecting it from power.

This label is applied to various batteries to indicate that the battery is not to be thrown away,
but rather reclaimed upon end of life per this Directive.
In accordance with the European Directive 2006/66/EC, batteries and accumulators are
labeled to indicate that they are to be collected separately and recycled at end of life. The
label on the battery may also include a chemical symbol for the metal concerned in the
battery (Pb for lead, Hg for mercury and Cd for cadmium). Users of batteries and
accumulators must not dispose of batteries and accumulators as unsorted municipal waste,
but use the collection framework available to customers for the return, recycling and
treatment of batteries and accumulators. Customer participation is important to minimize
any potential effects of batteries and accumulators on the environment and human health
due to the potential presence of hazardous substances.
