4.2System Drawer Architecture

The system drawer houses a QBB consisting of a backplane that supports four CPU modules, four memory modules, two power modules and two I/O riser modules. These modules are identical to those used in the box systems. The global port is part of the backplane. In a two- drawer system, the drawers are linked by a distribution board.
