The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Catalyst 4500 switches support the Cisco EnergyWise features and functions as previously described in this guide. This appendix describes any Catalyst 4500 switch-specific EnergyWise functions.
Catalyst 4500 switches running Cisco EnergyWise Version 2.6 and later:
High availability:
To perform an ISSU downgrade from a Cisco IOS release supporting Cisco EnergyWise Version 2.6 to an earlier software release that does not support EnergyWise, disable EnergyWise on the switch first.
To perform an ISSU downgrade from a software release supporting Cisco EnergyWise Version 2.6 to a release supporting EnergyWise Version 1, disable EnergyWise on the switch first because of CLI compatibility issues between EnergyWise Version 1 and EnergyWise Version 2.6.
To perform an ISSU downgrade from a Cisco IOS release supporting Cisco EnergyWise Version 2.6 to an earlier release that does not support EnergyWise, you must remove the snmp-server enable traps energywise global configuration command from the switch configuration.
During an ISSU upgrade from a software release supporting Cisco EnergyWise Version 1 to a release supporting Cisco EnergyWise Version 2.6, the EnergyWise settings in the running configuration are updated. The switch sets the management password to the same domain password as in the energywise domain command. You must enter the copy running-config startup-config privileged EXEC command to save the EnergyWise settings in the configuration file.
Stateful switchover (SSO) mode
Note | If your domain member is running Cisco EnergyWise Version 2.6 or later and you need to downgrade to Cisco EnergyWise Version 1.0 due to domain member compatibility issues, enter the no energywise domain global configuration command to disable EnergyWise before downgrading your software to a release supporting EnergyWise Version 1. |
