RAC & failing switch and power issues

Running a 2-node RAC on AIX (v5.3).
Oracle v10.2.0.3
Application runs in active-passive fashion.
We have issues with:
a) the switch that is the RAC interconnect
b) the power being supplied to that same switch
Our current idea is to shut down the passive instance (prod2).
We are assuming that this would leave us free to play games with the
switch.
Our software vendor is telling is this should be O.K.
Oracle is telling us that if we pull the switch after shutting down PROD2,
that the server running the active instance (PROD1) will "evict itself".
This flies in the face of some testing we did early this year where we
simulated loss of the switch
by shutting down the interfaces via ifconfig.
Would love to hear comments opinions about this situation.
Thanks in advance.
