A method tests hard disk ports located on a motherboard of a computing device. Each of the hard disk ports connects to a respective serial port of a test fixture. The test fixture includes a group of serial ports, a multiplexer and a storage device. Each of the hard disk ports is selected to be tested during the process of hard disk ports test. A data transmission path is formed by building a connection between the storage device and a channel of the multiplexer corresponding to the hard disk port. Data are written to the storage device and read from the storage device through the data transmission path. The hard disk port is working normal if the written data are identical to the read data. The hard disk port is not working normally if the written data are not identical to the read data.

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.

A test system and method for test performance of a multi-card reader includes identifying types of cards the multi-card reader can communicate with, obtaining a protocol of each type of card, and setting a protocol between the multi-card reader and the test system to one of the obtained protocols. Controlling the multi-card reader to read test data from a storage system of the test system and sending the read test data to the test system, testing performance of the multi-card reader by comparing the read test data with the test data stored in the storage system, to obtaining a test result according to the comparison.

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.

A router providing remote boot for computers includes a DHCP/proxy DHCP service module to send an IP address to a computer, in response to a DHCP Discover packet sent from the computer, a boot service module to send a DHCPACK packet, which includes a filename of a remote boot mirror image and configuration parameters of TFTP/MTFTP, to the computer in response to a BSDP packet sent from the computer, and a MTFTP/TFTP service module to establish a connection between the router and computer enabling the computer to download the remote boot mirror image according to the configuration parameters of TFTP/MTFTP, in response to a request packet sent from the computer.
摘要:
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.

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.

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.

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.

In a method for performing data backup and recovery in an electronic device, the method initializes a redundant array of independent disk (RAID) card of the electronic device when the electronic device is started up, receives preset configuration information of the RAID card, and stores backup configuration information of the RAID card in a storage device. The method further sets a flag value of the RAID card as a first value if current configuration information of the RAID card are not identical to the backup configuration information when the electronic device is started up at a next time, restarts the electronic device, updates the current configuration information of the RAID card with the backup configuration information, sets the flag value as a second value, and restarts the electronic device.
