               Standby failures = 0 

         Last switchover reason = none 

 

                  Hardware Mode = Duplex 

     Configured Redundancy Mode = sso 

      Operating Redundancy Mode = Non Redundant 

               Maintenance Mode = Disabled 

                 Communications = Down      Reason: Simplex mode
