Fault fltEqptdiagSubjOperStFailed
                
                    
                         Explanation:  
This fault occurs when a diagnostic test
                     fails. 
 
                         Recommended Action:  
 The failed diagnostic test isolates
                     the error to a port, card(FRU) or the entire switch.
                     For port-level errors, the port are put in disabled state.
                     For card or switch level errors, collect the show techsupport 
                     command output on the switch and contact Cisco TAC to eliminate
                     any known software issues before replacing the hardware.
