Came across a situation where powering off a module in a Cisco 4500 (Sup7-E) would have been nice, but couldn't seem to find the command. Ended up having to unseat the module until we had the fix in place and then someone had to go insert it again
Unfortunately, it was off site, so it required someone to go to the location to do this and it would have been nice to be able to do remotely.
I know with a 6500 you can do a no power enable module <#> (IOS) or set module power down <#> (CatOS) to power off the module, but just couldn't find it on the 4500.
Anyone have any suggestions or ideas? Hidden command maybe?
Or can anyone confirm the platform doesn't have the capability (and why)?
It seems somewhat odd to me that the capability to do a reset (hw-module [slot|module] <#> reset) of a module exists, but no capability to power it off entirely.

To power off a particular module, use
Switch(config)# no hw-module module _num_ power; you can find that command on Page 20 of this Cisco docFYI, there isn't a graceful shutdown command for the whole switch. You should backup your config (just in case), issue a reboot, wait till you can audibly hear a change in fan speed, and then remove power before system starts booting.
