Abstract: A fan box is provided with, in addition to an intake port in the front face, a second intake port at a wall surface position upstream of a fan. An Input/output unit disposed above or below the fan box comprises an exhaust notch that is aligned with the second intake port of the fan box, as well as an intake notch that is provided further to the rear than the exhaust notch. The intake notch is in communication with an air duct that opens in the front face of the processor and that leads to a unit box. The fan discharges through an exhaust port cooling wind that has flowed into the first intake port via an operation unit, as well as cooling wind that has flowed into the second intake port via the Input/output unit.

Abstract: In the invention, a finger board is bent like a “letter V”, and a thickness adjustment plate is provided between the finger boards of modules to be able to move, thereby being able to adjust the height of a finger. Such a configuration enables to increase the contact pressure of the finger by increasing the height of the finger when the finger is inserted, and when the finger is detached, reduce the contact pressure by reducing the height of the finger. This accordingly provides a shield chassis of suppressing any possible noise with no loss of insertability/removability.

Abstract: A server system has, in addition to extensibility of scale-out type of a braid server system, extensibility of scale-up type by making SMP coupling among nodes. Each node has a unit for SMP coupling to other nodes. A module management unit responds to system configuration information to switch between a mode in which the node operates singularly as a braid server and a mode in which the node operates as a constituent module of an SMP server. Links among individual nodes are laid through equidistant wiring lines on a back plane and additionally a loop wiring line having a length equal to that of the inter-node link on the back plane is also laid in each node, thereby setting up synchronization among the nodes. Synchronization of reference clocks for SMP coupled nodes is also established.

Links among individual nodes are laid through equidistant wiring lines on a back plane and besides a loop wiring line having length equal to that of the inter-node link on back plane is also laid in each node, thereby setting up synchronization among nodes. Each node has a reference clock distribution unit mounted on back plane and adapted to distribute reference clocks to individual nodes and by switching reference clocks by a clock distributor inside each node, synchronization of reference clocks for SMP coupled nodes can be established.
