Monarch/Slave SmartSwitch 9000 Modules
All modules in an SmartSwitch 9000 chassis that transfer packets across the INB
backplane have identical INB interfaces. However, one of them has to be selected
to perform the backplane arbitration. The lowest slot number module will
automatically be selected as the arbitrator. This module will be called the
Monarch and others will be Slaves to that module. If the Monarch module is
removed from the chassis, a re-election occurs and the module with the lowest
slot number is elected Monarch.
