The fan module dissipates heat for the chassis so that the chassis can work properly and efficiently within the operating temperature range.
Noise reduction
When the fan module is powered on, it rotates at 48% of the full speed for at most 5 minutes. After the fan module communicates with the MPU normally, the MPU controls running of the fan module.
Automatic fan speed adjustment
After the fan module communicates with the MPU normally, the MPU controls the speed of the fan module according to temperature of cards in the chassis.
Alarm report
The fan module can report alarms on fan module failures and communication failures.
Electronic label
The MPU reads and loads the electronic label of the fan module through RS485.
Hot swapping
Supported

FAN-240SB-B FAQ
Q1: Which Huawei switch models does the FAN-240SB-B support? How compatible is it?
A1: It mainly supports some mid-to-high-end Huawei CE8800 series switches, some models of the CE7800 series, and high-end models of the CE6800 series. The size and interfaces are fully matched, with 100% compatibility; it can be used simply by plugging and unplugging.
Q2: Does the lightweight design affect heat dissipation? Can it meet the heat dissipation requirements of a switch under normal load?
A2: The lightweight design focuses on the core heat dissipation area, combined with directional airflow technology, resulting in precise and efficient heat dissipation. It fully meets the heat dissipation requirements of mid-to-high-end switches under normal and light heavy loads, and the core temperature can be controlled within a safe range.
Q3: How is redundancy deployment achieved? Will a single module failure affect equipment operation?
A3: It supports N+1 redundancy deployment of 2 or more modules. The switch system monitors the status of each module in real time. After a single module fails, the remaining modules automatically accelerate to fill the gap, the heat dissipation capacity is not affected, and the equipment continues to operate normally.
