Description (partial)

 are repeatedly reported ~ every 4-8 minutes and all PEM's are down 
 from Power Management perspective.
 If power management is not enabled, the router keeps
 operation normally, "show environment power-supply" 
 indicates normal voltage and current for all PEM's.
 This is triggered by unusual circumstances such as a manually triggered
 software reset of the mbus agent of the busboard controller. Other triggers
 may exist.
 The fix also addresses sporadic POWERMGR-4-PEM_DOWN messages.
