摘要:
An exemplary signal collection system includes a signal transmitting module and a computer. The signal transmitting module outputs a high-speed signal with a high frequency. The signal collection system further includes a data collection module interconnecting the signal transmitting module and the computer. The data collection module includes a frequency reduction unit. The frequency reduction unit reduces the frequency of the high-speed signal output from the signal transmitting module and outputs the high-speed signal with a reduced frequency to the computer. A signal collection method based upon the signal collection system is also disclosed.

A circuit board system for connecting with at least an expansion card that includes a Programmable Logic Device (PLD) electrically coupled to the expansion slot. The PLD is configured to detect whether the expansion card is compatible with the circuit board system. If the PLD detects that the expansion card is not compatible with the circuit board system, the logic controller cuts off the connection between the main power supply and the expansion slot.

A start-up control apparatus includes a switch, an advanced configuration and power interface (ACPI) controller, a power supply, and a control chip. The switch creates a trigger signal. The trigger signal includes a first falling-edge and a first rising-edge. The control chip includes a control module and a monitoring module. The monitoring module sends a status signal about the power supply to the control module. The control module receives the first falling-edge and sends a second falling-edge to the ACPI controller according to the status signal after receiving the status signal. The ACPI controller sends a control signal to the power supply to enable the power supply to change from a first status to a second status. The control module sends a second rising-edge to the ACPI controller before receiving the first rising-edge when the power supply is in the second status.

A monitor and control system includes a server model, a number of switches, a temperature sensor mounted in the server model, a monitor and control device, and a microcontroller. The switches are connected to the resistors to control current through the resistors. The temperature sensor is mounted in the server model. The monitor and control device is connected to the server model and configured to monitor and control the server model. The microcontroller is configured to switch the switches on and off and send temperature information sensed by the temperature sensor to the monitor and control device.

In a server management method, a blade server system including a plurality of blade servers is connected to a monitor device in series. The monitor device sends a command to the server system to control the plurality of blade servers. The plurality of blade servers responds to the command. The monitor device receives information from the server system to monitor and control the plurality of blade servers. A server monitor system associated with the server monitor method is also disclosed.

A start-up control apparatus r includes a control chip, an advanced configuration and power management interface (ACPI) controller, and a firmware. The ACPI controller is used for receiving a trigger signal and sending a start-up signal corresponding to the trigger signal to the control chip if a computer system is powered off. The firmware is used for sending a status signal to the control chip after the firmware finishes initialization. Wherein the control chip is used for sending the start-up signal to a power supply to provide power for powering on the computer system after receiving the status signal.

A testing method for a fan module is provided. When the fan module is tested, a testing computer sends a testing command to a testing device first. Then, the testing device responds to the testing command and controls the fan module to work in a plurality of rotational speed modes in sequence. The testing device reads an actual rotational speed when the fan module works in one of the rotational speed modes and sends the actual rotational speed back to the testing computer. The testing computer compares the actual rotational speed with a corresponding reference rotational speed value stored in the testing computer, and determines the testing result. Finally, the testing result is shown.
