Appeal No. 2000-0258 Page 2
Application No. 08/577,897
invention can be derived from a reading of exemplary claim 1,
which is reproduced as follows:
1. In a data processing system that includes a number of
system components and one or more redundant system components, a
method for protecting the system components from transients that
arise on a system interconnect during switching events,
comprising:
the system components operating in a normal mode of
operation;
detecting that a switching event, wherein a first redundant
system component replaces a failed system component, is to occur;
indicating to the system components that the switching event
is to occur; the system components entering a standby mode of
operation wherein each of the system components isolate their
circuitry from the system interconnect during the switching event
by tri-stating respective interfaces to the system interconnect;
and
the system components returning to the normal mode of
operation in response to a triggering event.

examiner in rejecting the appealed claims are:
