    摘要: 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.

    摘要: In a method for switching between multiple system hosts (154,164,174,184) on a CompactPCI bus (110,120), a hot swap controller (166,186) provides to a special arbiter (820) a high priority request signal and the special arbiter (820) provides to the hot swap controller a grant signal only when the CompactPCI bus is idle. The hot swap controller (166,186) provides to the special arbiter (820) a float signal causing the special arbiter (820) to disable the system host signals, which include one or more grant signals for granting bus access to devices on the CompactPCI bus (110,120), one or more reset signals for resetting the devices, one or more interrupts and one or more clock signals provided to devices. The hot swap controller (166,186) transfers control of the CompactPCI bus (110,120) to a standby system host 154,164,174,184).
