摘要： PROBLEM TO BE SOLVED: To provide a server system which has, in addition to extensibility of scale-out type of a conventional blade server system, extensibility of scale-up type by making SMP (Symmetric Multi Processing) coupling among a plurality of blade server modules. SOLUTION: A node controller in each blade server module has an SMP coupling interface, and is coupled via a back plane. Links among individual blade server modules are laid through equidistant wiring lines on a back plane and besides a loop wiring line having length equal to that of the links among the individual blade server modules on the back plane is also laid in each blade server module, thereby setting up synchronization. Each blade server module has a reference clock distribution unit mounted on the back plane and adapted to distribute reference clocks and by switching reference clocks by a clock distribution circuit inside each blade server module, synchronization of reference clocks for SMP coupled blade server modules can be established.

摘要： PROBLEM TO BE SOLVED: To perform insertion/extraction of a circuit board card easily, safely and with reliability irrespective of whether hot-line insertion/extraction is required or not. SOLUTION: A frame 6 having a handle 5 to be held by a worker when inserting/extracting the circuit board card 3 is attached to the circuit board card 3 by using stay mechanisms 9a, 9b. By mounting the circuit board card 3 onto an electronic equipment case 1 in this state, the worker need not touch the circuit board card 3 itself for insertion/extraction of the card 3, and can complete extraction only by holding the handle 5 attached to the card 3 to be extracted and simply pulling it up. The frame 6 having the handle 5 functions as a top cover of the electronic equipment case 1. This eliminates the need for opening any top cover of the case or door for insertion/extraction, and thereby prevents secondary troubles such as dropping an object into the inside of the equipment.

摘要： PROBLEM TO BE SOLVED: To provide a module insertion/extraction structure capable of reducing radiation noise without impairing operation performance.
SOLUTION: The height of a finger 1032 can be adjusted by bending a finger mount plate 1030 into a valley fold and providing a movable thickness adjusting plate 1034 in the finger mounting plate 1030 of a module. Consequently, the finger height is increased during insertion to increase contact pressure of the finger 1032, and decreased during detachment to decrease the contact pressure of the finger 1032. With this structure, a shield housing structure is obtained which suppresses noise without impairing insertion/extraction operability.

摘要： PROBLEM TO BE SOLVED: To provide a server device having scale-up scalability with SMP joint between a plurality of blade server modules in addition to scale-out scalability of a conventional blade server system. SOLUTION: A node controller in each blade server module has a SMP joint interface, and it is joined via a back plane. A link between the blade server modules is isometrically wired on the back plane, and a loop is also wired in each blade server module at a length equal to that of the link between the blade server modules on the back plane for synchronizing operation. A reference clock distribution unit is mounted on the back plane for distributing a reference clock to the blade server modules. The reference clock is switched by a clock distribution circuit in each blade server module, thereby permitting the synchronization of the reference clock for the SMP-joint blade server modules.

摘要： PROBLEM TO BE SOLVED: To overcome the problem in the cooling method of a rack mounting information processor that sufficient cooling of a high heat generation element is difficult because the mounting space of a cooling fan can not be ensured because of compaction of the rack and that a special cooling environment, e.g. cooling water or underfloor air supply, is required when a water cooling system is employed. SOLUTION: A water cooling arrangement is provided in a compact rack, water cooling refrigerant channels are provided in a plurality of columns constituting a cabinet incorporating a water cooler, cooling refrigerant is supplied into the rack from at least one column and the cooling refrigerant, absorbed heat in the rack, is fed to at least one remaining column thus cooling each information processor. Since the cooler is incorporated in the cabinet, closed cooling can be realized without requiring any special cooling environment.

摘要： PROBLEM TO BE SOLVED: To provide a power-supply system of a structure, that even if the kinds of an operating voltage of an LSI are increased, no need is required to increase the number of power-supply layers in a PCB, it is eliminated, to oppress the mounting region of the LSI to narrow the mounting region, and malfunctions of the system due to fluctuation in a power supply can be prevented. SOLUTION: A lower fixing plate 5 has a structure which is integral with a power supply module for feeding a power supply to an LGA 1. As the plate 5 is formed in the structure integral with the power-supply module, the plate 5 is provided with a power-supply terminal 6. This terminal 6 can feed power to the LGA 1 by electrically contacting with a PCB 3. The contact of the terminal 6 with the PCB 3 is executed via a rocket 7, whereby as the power supply can be fed to a pin of the LGA 1 without needing power-supply layers in the PCB 3, and the feed of the power supply at a low impedance can be realized. Moreover, since the plate 5 and the power-supply module are formed integrally, overpressuring of the mounting region of an LSI can be solved without separately needing a module.

摘要： PROBLEM TO BE SOLVED: To automatically start up a load device when a commercial power source recovers by providing a power source control part which sends a power-ON signal by an auxiliary power startup of a device power source. SOLUTION: The power source control part 4 is composed of an auxiliary power source control part 10 which when the commercial power source is connected to the device power source 5 and the auxiliary power source starts up, senses that and outputs a signal and an event holding relay 9 which turns off when the main control part 6 senses an output signal in case of power failure occurrence from the output 2 of a primary power stop contact. When a recovery from the power failure is made and the commercial power source 1 is connected to an uninterruptive power unit 3, the uninterruptive power unit 3 connects the commercial power source 1 to the device power source 5 of the load device 7. The device power source 5 once supplied with electric power starts up the auxiliary power source which enables the power source control part 4 to send a power-ON signal. This power source control part 4 senses the electric power from the device power source 5 rising through an auxiliary power source sense part 10 and sends the power-ON signal on condition that the event holding relay 9 is OFF. Thus, the load device 7 is automatically started up.

摘要： PROBLEM TO BE SOLVED: To provide a printed wiring board at a low cost which can detect the burning of a printed wiring board which is caused by short-circuit of an electronic component or the like mounted on the board. SOLUTION: A burning detecting pattern 20 which is formed of the same material as the ordinary wiring material with the same process is disposed on a printed wiring board. When the burning of the printed wiring board 1 progresses and the pattern 20 is burned out, an inverter gate 13 outputs a burning detection signal 21, and cuts off a power source to the printed wiring board 1.
