A multiconfiguration backplane (100) can be configured in four different configurations: dual, extended, active/standby and active/active. The multiconfiguration backplane (100) has a first CompactPCI bus (110) with a first system processor slot (112), a first bridge slot (114), and a first se t of one or more input/output slots (116). The multiconfiguration backplane ha s a second CompactPCI bus (120) with a second system processor slot (122), a second bridge slot (124), and a second set of one or more input/output slots (126). A first cross connection (130) is between the first system processor slot (112) and the second bridge slot (124), and a second cross connection (140) is provided between the second system processor slot (122) and the fir st bridge slot (114). Preferably, the first cross connection is a first local P CI bus and the second cross connection is a second local PCI bus.
