Upgrading Software in an Existing Stack
Upgrade all stacked switches at the same time. The Master controls the upgrade
process. Use the following procedure to perform a software upgrade for a stacked
system.
1. Load new software on the Master.
The Master pushes the new software image to all Members in the stack, as
follows:
– If the new software is loaded into image 1, the Master pushes the software
into image 1 on all Members.
– If loaded into image 2, the Master pushes the software into image 2 on all
Members.
The software push can take several minutes to complete.
2. Verify that the software push is complete. Use either the BBI or the ISCLI:
– From the BBI, go to Dashboard > Stacking > Push Status and view the
Image Push Status Information, or
– From the ISCLI, use following command to verify the software push:
3. Reboot all switches in the stack. Use either the ISCLI or the BBI.
– From the BBI, select Configure > System > Config/Image Control. Click
Reboot Stack.
– From the ISCLI, use the following command:
RS G8000(config)# show stack push-status
