Working with a 6500 chassis running on a single SUP720-3B.
For some reason, the power redundancy mode is showing "mode sso".
What's the proper config mode for a single sup chassis and how to change that?
as Kevin has noted these commands should have no effect on your single supervisor chassis.
they are probably inserted by default in the IOS image you are using to make the system ready for addition of a second supervisor.
Hope to help
