A method and system for controlling the state of the system bus (32) during live insertion and removal of pluggable cards (FC) (34-37) by driving bus signals to a predetermined state. Thus making the system bus immune to signal disturbances. During live insertion and removal, a live insertion bus controller (LIBC) (30) accesses the system bus through interface (38) with system bus controller (SBC) (33), after receiving an indication that the FC is in the process of being live inserted or removed. The LIBC (30) then drives a subset of the control signals to a state that is immune to signal disturbances. The LIBC (30) effects suspension of running timeout and watchdog operations being performed by the SBC (33). When live insertion or removal is completed control is returned to the SBC (33). |
