Can i lower cisco 4506 power consumption.

Your line card and supervisor card will draw the required power to "power up", however, your PS will draw the MAXIMUM power it's required.  So I really don't understand how you can "save power".

The only way to "save power" is to use a single power supply.  But this means that if you loose this power supply, you loose your network.

That's right.  The Power Calculator will help you determine what PS to use using different line cards as a scenario.

  You can turn off the power to the poe ports if not needed .  The power is determined by the size of the installed power supplies .  You can check into enrgywise , haven't tried it myself and have never seen it discussed in here before.

I'm using EnergyWise.  I don't see any relevance as to WHY you would want to use it.  I also don't see any information about your PoE requirement, hence, no comment on how you'd like to save money by powering down PoE.  

The power requirement for the 4506 would, most likely, be LESS than getting six PoE switches individually. 

I mean, if you don't use PoE, the line cards will only draw what is required.  So trying to save money from energy consumption of the chassis won't make a lot of sense.

I means if I want to lower power usage from chassis + supervisor engine + some line card I use how I can do it. So if you tell me it just low/Not very different such as we require on most l3 poe switch then I will feel comfortable to using it.
