More Information
Summary:The invention provides a communication device and a method for controlling the same. The rotating speed of a cooling fan is controlled in accordance with the number of devices connected to ports of a packet transmitting/receiving unit and a connection speed with that device. When the number of ports establishing a link at a speed of 1 Gbps is zero, the voltage value of power output from a power source block to the cooling fan is 0 V and the cooling fan is deactivated. When the number of ports establishing a link at a speed of 1 Gbps is one or two, the voltage value is 8 V and the cooling fan rotates in a slow mode. Furthermore, when the number of ports establishing a link at a speed of 1 Gbps is three or four, the voltage value is 12 V and the cooling fan rotates in a fast mode.
