Circuit board for on-line insertion in computer system.

摘要

A circuit board is provided for on-line insertion into a computer system which has a plurality of clock lines including a clock line for the board, a bus and a system initialization line carrying a system initialization signal. The circuit board interrupts traffic on the bus during insertion of the board and decouples the clock line for the board from the other clock lines. The circuit board also provides fully distributed synchronization of the system initialization signal.
