Not that I know, but make certain that you use the 'option' attribute to 
make certain both power supplies are off, before they are turned on 
again. The default behavior is reboot, and it is possible for both 
supplies to never be off at the same time - hence the machine is never 
rebooted

In the cluster.conf file, it would look like this:
<clusternode name="node1">
  <fence>
   <method name="1">
    <device name="my_apc" port="1" option="Off"/>
    <device name="my_apc" port="2" option="Off"/>
    <device name="my_apc" port="1" option="On"/>
    <device name="my_apc" port="2" option="On"/>
  </method>
 </fence>
</clusternode>
