ABSTRACT:
A modular node assembly for a rack mounted multiprocessor computer in which the node assembly has a logic chassis and a removable chassis. The logic chassis contains logic cards including memory cards, a service processor card, Central Processing Unit (CPU) processor cards, and Input/Output (I/O) cards to which I/O and processor interconnecting cables are attached. The removable chassis contains the power supply module for the node, a node supervisor card, disk drives and cooling fans. The removable chassis is removable from the logic chassis without moving or disturbing the logic chassis. One fan of a pair of cooling fans in the removable chassis draws air through the power supply, which has relatively higher cooling needs, and blows the air into the logic chassis over logic modules having relatively lower cooling needs. The other cooling fan draws air over the disk drives and node supervisor card which has relatively low cooling needs, and blows air over into the logic chassis over logic modules having relatively higher cooling needs.
