Firmware Upgrade for a Stacking System

The running firmware images of all switches in the Stacking System should be the same firmware version.

The same firmware version for all Slots
Upgrade Master via FTP/TFTP/Console => Apply to all Slots
Upgrade firmware for each/all Slots via web GUI => Centralized by Master
DO NOT downgrade the firmware to of any slot to one that does not support Stacking

If there is one switch with a different firmware version, the Master will not initialize that Slot and that Slot will become a new Stacking System.

Users can upgrade dual images to all member switches through the Master.

Besides, upgrading the firmware image in the Master via FTP/TFTP/Console will apply to all members in the Stacking System.

Enter the web GUI of the Master

Go to Management > Maintenance > Firmware Upgrade

Users can select a specific Slot or all Slots to upgrade the firmware image.

It takes 3 minutes for the system to program the firmware

Users can enter the command

show stacking slot <ID>

via CLI to check if flash 1 has been upgraded with the current firmware version as displayed.

Reload config 1/config 2 via web GUI to reboot the Stacking System and run new Firmware.
