NOTE
It is recommended that you replace the air filter of a device every six months.
The S7700 cooling system consists of a fan module and an air filter. The fan module is located
behind the air exhaust vent (rear of the chassis), and the air filter is located outside the air intake
vent (left side of the chassis).
l
The fan module can intelligently adjust the fan speed. It absorbs cold air into the chassis
to dissipate heat generated by working components, ensuring that the chassis operates
within a normal temperature range. For the performance and attributes of the fan module,
see 
l
The air filter prevents dust from entering the chassis and ensures normal operation of the
chassis.
Fan Zones
The S7706 and S7712 chassis are divided into multiple zones. If there are empty slots in a zone,
the fans corresponding to this zone operate at a low speed, which reduces power consumption
and noises.
As shown in 
, two fan modules of the S7706 serve two zones, with four cards in
each zone.

The S7712 chassis is divided into multiple zones. If there are empty slots in a zone, the fans
corresponding to this zone operate at a low speed, which reduces power consumption and noises.
As shown in 
, four fan modules of the S7712 serve four zones, with four cards in
each zone. The cards in slots 4 and 9 each belong to two zones and are cooled by two fan modules.
