Intelligent fan speed adjustment |
The S12700E series switches provide intelligent fan speed adjustment based on temperature in each zone, and correlate speeds of fans in the entire chassis. The system monitors the temperature of key components, and adjusts the fan speed based on temperature changes. This intelligent fan speed adjustment function ensures that the system stays within the proper operating temperature range, and reduces power consumption and noise. |
Each fan module has two fans and can work for a short time when one fan fails. When any fan in a fan module fails, handle the failure immediately to ensure that the fan module can work normally.
