Abstract: A test fixture includes a first RS-232 connector and a second RS-232 connector. The data terminal ready (DTR) pin of the first RS-232 connector is connected to the DTR pin of the second RS-232 connector, and the clear to send (CTS) pin of the first RS-232 connector is connected to the CTS pin of the second RS-232 connector. The DTR pins are further connected to a power pin of each of the test computers. The test fixture sets a high level voltage for the connected DTR pins, and sets a low level voltage for the connected CTS pins according to the commands of turning on the test computers sent by the control computer, to turn on the test computers. An auto shutdown software included in each of the test computers is executed to shut down the test computers.

Abstract: In a system and method for testing a serial port of a computing device, the serial port electronically connects to a test fixture. Test data is sent to a receive data (RXD) pin by a transmit data (TXD) pin. A test result is received from the serial port by the RXD pin. The TXD pin and the RXD pin work normally if the test data is identical to the test result. When voltages of a request to send (RTS) pin and a data terminal ready (DTR) pin are set at high level, the RTS pin, a data carrier detect (DCD) pin, the DTR pin, a ring indicator (RI) pin, a data send ready (DSR) pin and a clear to send (CTS) pin work normally, upon the condition that status values of the serial port indicate the voltages of the above six pins are at high level.

Abstract: A method controls power of a baseboard management controller (BMC). A power control signal of the BMC is generated for powering up or powering down the BMC. An enabling signal is generated according to the power control signal. A power supply device is directed to output one or more voltages to the BMC.

Abstract: A preboot execution environment (PXE) test device includes a microprocessor, one or more indicators, a network interface, a power connector, and a storage device. The network interface connects the PXE test device with a computer. The power connector connects an external power source to supply a voltage to the PXE test device. The storage device stores a boot loader, an embedded operating system, and one or more programs. The microprocessor executes the boot loader and the embedded operating system to start the PXE test device. The one or more indicators indicate a power supply status and a starting status of the PXE test device. The microprocessor further executes the one or more programs to remotely boot the computer for test PXE of a network card in the computer.

Abstract: A server includes a Southbridge chip, a first storage device, and a baseboard management controller (BMC) electrically connected to the Southbridge chip. A field replacement unit (FRU) is electrically connected to the BMC and the first storage device. The BMC reads data from a second storage device electrically connected to the BMC, writes the data into the FRU, sends a first control signal to a switch positioned between the BMC, the first storage device and the FRU, to switch on an electrical connection between the BMC and the first storage device for reading data stored within the first storage device. If the data stored within the first storage is different from the data stored within the FRU, the BMC reads the data from the FRU, and writes the data into the first storage device, to synchronize the data within the first storage device and the FRU.

Abstract: In a method for testing a preboot execution environment (PXE) function of a NIC of a server, an IP address is allocated for the NIC by sending a DHCP offer message to the NIC in response to receiving a DHCP discover message from the NIC. TFTP parameters are provided to the NIC by sending a DHCP ACK message to the NIC in response to receiving a DHCP request message from the NIC. A connection based on a MTFTP or a TFTP between the BMC and the NIC is established according to the TFTP parameters. A PXE image file is provided to the NIC for downloading through the connection in response to receiving a request for downloading the PXE image file from the NIC, and the downloaded PXE image file is executed to test whether the PXE function of the NIC is normal.
