Multi-part concurrently maintainable electronic circuit card assembly
First Claim
1. An electronic system, comprising:
- a frame for housing a plurality of electronic modules;
a backplane circuit card assembly mounted to the frame, said backplane circuit card assembly comprising;
(a) a plurality of base circuit cards, and(b) at least one jumper circuit card, said at least one jumper card being pluggably coupled to said plurality of base circuit cards and providing a plurality of electrically conductive paths between base circuit cards; and
a plurality of electronic modules mounted to said frame for redundantly performing at least one function necessary for operation of said electronic system, each of said electronic modules being pluggably coupled to a respective base circuit card;
wherein, with respect to each of said plurality of base circuit cards, it is possible to remove the respective base circuit card from said electronic system and replace the respective base circuit card while said electronic system remains operational, the remainder of said plurality of base circuit cards providing redundant function for the respective base circuit card being removed.

Abstract
An electronic system contains a backplane circuit card assembly for distribution of electrical signals to one or more modules. The card assembly includes a plurality of pluggably connected base cards, which provide redundant function. Preferably, two base cards in a single plane are connected by a single smaller parallel offset jumper card, the cards being coupled by pluggable connectors. The system preferably includes redundant power supply modules and redundant functional modules, which plug into the backplane from both sides. The modules connected to any one of the base cards provide minimum system functionality in the absence of the other card and its modules. Due to the redundant function, it is not only possible to replace any module, but is possible to replace a base card itself, while the system remains operational. The exemplary embodiment is an intelligent redundant array of independent disks (RAID) storage server having concurrent maintenance capability.
