Upgrading Each Device in a Chassis Cluster Separately
Devices in a chassis cluster can be upgraded separately one at a time; some models allow one device after the other to be upgraded using failover and an in-service software upgrade (ISSU) to reduce the operational impact of the upgrade.
To upgrade each device in a chassis cluster separately:
 | Note: During this type of chassis cluster upgrade, a service disruption of about 3 to 5 minutes occurs. |
- Load the new image file on node 0.
- Perform the image upgrade without rebooting the node by
entering:user@host> request system software add image_name
- Load the new image file on node 1.
- Repeat Step 2.
- Reboot both nodes simultaneously.
