Getting Started Guide 17System InitializationIf the Master Switch determines during the firmware version consistency check that all switches are runningthe same version of firmware, the switch will be initialized for Stacking Mode.System Initialization for Normal Stacking ModeThe Master Switch will initialize the stack using the last saved system configuration file. For those switchesthat do not have a configuration file, the system will apply default settings to those switches.If the configuration file is corrupted, the Master Switch will initialize the stack and set it to the Factory DefaultConfiguration.You can save the configuration file. The Master Switch will automatically distribute the configuration file tothe member switches. If the Master Switch later becomes unavailable, a Member Switch can become the newMaster Switch and apply the configuration file that was saved on the original Master Switch.System Initialization for Suspended Stacking ModeAfter system initialization is complete, the Master Switch will enter Suspended Stacking Mode if the firmwareversions of the stack are inconsistent. In this mode, only the Master Switch is initialized with configuration fileinformation. None of the member switches are initialized. This forces all member switches to remain in non-operational mode.NOTE: All ports disabled by default.CLI/ Telnet/ Web InterfaceYou can use the CLI / WEB / SNMP to synchronize the firmware that is stored in the Master Switch to a memberswitch.Insertion and Removal of SwitchesYou can insert and remove switches to/from the current stack without cycling the power. The entire network maybe affected when a topology change occurs, as a stack reconfiguration will take place. A new Master Switch willnot be re-elected, unless the Master Switch was removed from the stack. Stack reconfiguration takes a maximumof two minutes in a stack of twelve switches, less time for smaller stacks.Operating as Standalone SwitchIf a switch cannot detect a stacking partner on a port enabled for stacking, the switch will operate as a standaloneswitch. If a stacking partner is detected, the switch will always operate in stacking mode.Stack ID RenumberingYou can manually assign Stack IDs to a switch. A switch can only be assigned a Stack ID that has not alreadybeen assigned to another switch in the stack. Any configuration information that was saved for the new Stack IDis applied to the switch that is taking that Stack ID.
