Note Prior to downgrading to a specific release, check the release notes for the current release installed on the switch, to ensure that your hardware is compatible with the specific release. There are special caveats you must be aware of before you downgrade the switch software to a 4.0(0)-based release. See the Cisco Nexus 5000 Series and Cisco Nexus 2000 Series Release Notes for details. To downgrade the software on the switch, follow these steps: OL-16597-01 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide 33
