In a method for switching between multiple system processors (152,172) on a CompactPCI bus (110,120), when a standby system processor (172,152) determines a failure affecting an active system processor (152,172) on the CompactPCI bus (110,120), the standby system processor (172,152) places a special arbiter (820) in a one master mode. If the standby system processor (172,152) determines that a device is at risk of performing a destructive action, the standby system processor (172,152) quiesces the device. The standby system processor (172,152) then places the special arbiter (820) in a multiple master mode.
