摘要： PROBLEM TO BE SOLVED: To provide a transmission/reception circuit for simultaneous bidirectional transmission which is capable of stably performing transmission/reception corresponding to the load condition of a transmission path.
SOLUTION: In the reception circuit of a transmission/reception circuit, a differential amplifier circuit 3 compares a signal voltage with a reference voltage to generate a reception signal. To prevent an error generated in the reception signal because the through rate of the signal voltage does not match the through rate of the reference voltage, the through rate of the reference voltage is adjusted so as to match the through rate of the signal voltage.

摘要： PROBLEM TO BE SOLVED: To provide a method of locating the physical position of a PCIe Card on an I/O drawer where a fault has occurred, regarding a blade server system having the I/O drawer.SOLUTION: An I/O drawer control ware (IOD) provided inside the I/O drawer has a first writing function for writing an I/O drawer number in the register of the PCIe Switch, and a second writing function for writing the physical slot number of the PCIe Card in a register inside the Downstream Port of the PCIe Switch. If a fault occurs at the PCIe Card, an EFI of a server blade reads the register in the PCIe Switch, thereby the I/O drawer number and the PCIe Card physical slot number can be known as identifiers and this information can be reported to an SVP. On receiving the report, the SVP outputs the installed position of the faulty PCIe Card to a log thereby the PCIe Card where the fault occurred can be identified.

摘要： PROBLEM TO BE SOLVED: To prevent erroneous operation by noise by distinguishing between a signal having attenuated amplitude and the noise when long-distance and high-frequency transmission is needed.
SOLUTION: Relay buffers 600, 601, 602, 603 of a computer module 110 and an I/O module 120 each have a noise filter circuit deciding signal amplitude of a PCIe (Peripheral Component Interconnect Express) interface 161, 162, distinguishing between the signal and the noise, and controlling ON/OFF of an output signal. An I/O HUB 300 and a PCIe switch 400 change over effectiveness/ineffectiveness of the noise filter circuits of the relay buffers according to a communication mode, and make the noise filter circuit ineffective when communication speed is high. Cable pulling-out detection circuits 115, 125 notify the IO HUB 300 and the PCIe switch 400 about pulling-out of a PCIe cable 151, and suppress the erroneous operation by the noise by a glitch of the PCI.

SOLUTION: In a server composed of a server module having a processor therein, an I/O module having an I/O extension adapter to expand the server's I/O capability, and a management module managing the entire server. The server module and the I/O extension adapter are interconnected using a PCI Express interface and the I/O module and the management module are interconnected using a special interface transferring detection information indicating whether an I/O extension adapter is actually mounted. In the event of a link failure on the PCI Express interface, link recovery is attempted by grasping the status of the link based on the detection information obtained through the special interface.
