The EnergyWise Capable grouping was meant to convey the fact that these devices might be capable with the right IOS version, not that they are immediately ready for EnergyWise management. Apparently, this is not what it says to you.
How would you verbalize the different groupings we are aiming for:
1. EnergyWise Enabled - has EW up and running on the device
2. EnergyWise Disabled - has EW on the device but it is currently disabled
3. EnergyWise Capable - is the right hardware family that might be EW capable with the right IOS version
4. Not EnergyWise Capable - does not appear to be a device that is currently able to support the EW technology.
Thanks for your feedback.
The EnergyWise Disabled group would definitely be a good idea. From here, only that group would allow you to "Enable" EnergyWise.
This would be a lot easier and reduce someone making the mistake of configuring a feature that didn't have the correct IOS to do so.
I had the same issue with a 3750. I had put code level 12.2.50-SE2 on the switch.
When I went to manage it on the energywise page, I got the message that the IOS is not supported.
I had to rediscover the switch, then it let me manage through the energywise page.
