Secondary NetEnforcer Activation
When two NetEnforcers are connected in Parallel Redundancy mode, the Secondary
NetEnforcer will take control and become the active unit under the following
conditions:
•
Upon a Primary subsystem failure.
•
During booting of the Primary NetEnforcer platform. When booting is
completed, the Primary unit automatically takes control again.
•
Upon any Primary NetEnforcer power feed failure and power OFF condition.
•
Upon the Primary NetEnforcer Ethernet cable disconnecting from either the
Internal or External ports. After reconnecting the cable and rebooting, the
Primary NetEnforcer takes control again.
•
When the Bypass Unit is not connected properly to the NetEnforcer Backup
connector, even with all other connectors fully plugged.
NOTE If a cable is disconnected, it is recommended to reboot the Primary
NetEnforcer after reconnecting the cable.
