Getting Started Guide 15Auto Stack ID AssignmentDuring the stack formation process, every switch is assigned a Stack ID. Once Stack ID assignmentis complete, each switch saves its Stack ID into the nonvolatile FLASH memory. You can usethe CLI or the Web interface to view the stack IDs.Firmware Version CheckingFollowing Stack ID assignment, the Master Switch performs a consistency check to make surethat all switches in the stack are running the same firmware version.If the switch software versions do not match, then the ports on the member switch will not becomevalid for operation. This condition is known as the Suspended Stacking Mode. You can thensynchronize the firmware on the member switch with the firmware that is running on the MasterSwitch.System InitializationIf the Master Switch determines during the firmware version consistency check that all switches arerunning the 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 thoseswitches that do not have a configuration file, the system will apply default settings to thoseswitches.If the configuration file is corrupted, the Master Switch will initialize the stack and set it to theFactory Default Configuration.You can save the configuration file. The Master Switch automatically distributes the configurationfile to the member switches. If the Master Switch later becomes unavailable, a Member Switchbecomes the new Master Switch and configures the stack with the latest configurationsynchronized from the Master Switch.System Initialization for Suspended Stacking ModeAfter system initialization is complete, the Master Switch will enter Suspended Stacking Modeif the firmware versions of the stack are inconsistent. In this mode, only the Master Switch isinitialized with configuration file information. None of the member switches are initialized.This forces all member switches to remain in non-operational mode.NOTE: All ports disabled by default.
