Abstract
In a method for swapping a system host board (150,160,170,180), when a failure is detected on a first system processor board (150), control of a first CompactPCI bus (110) is transferred from a first system processor board system host (154) to a first bridge board system host(164). In an active/standby configuration, control of a second CompactPCI bus (120) is transferred from a second bridge board system host (184) to a second system processor board system host (174), and control of the devices on the first CompactPCI bus (110) and second CompactPCI bus (120) is transferred from the first system processor (152) to the second system processor (172) without resetting any devices on the system.
