Energy - efficient features on Aruba Switches

Hello i was wondering if you Aruba guys got some kind of study with numbers of money saving with this kind of feature in which you can shut down APs during specific times.
Like how much energy an AP consumes and how much energy and money it will save you turning these off
Cheers

Carlos,
We have not done an official study on this but it is a great idea. We do publish the AP power power consumption values (on their respective datasheets) and while this is typically the maximum needed when serving clients, I typically see our APs at least draw 5 watts (if not more) when idle. If a customer is using X number of APs, you could tell them that when the WiFi is not needed, they would save X*5-watts if they used time of day PoE profiles. Additionally, you could also use time of day PoE profiles for other PoE devices like IP phones in non-critical areas.
You can always verify the PoE load on a Mobility Access Switch using "show poe controller" for the aggregate PoE consumption or "show poe interface brief" for a port by port display of PoE consumption.
Best regards,
Madani

Hello
Thanks for the reply
I was looking this because i would like to show the client something like this
Like in a year you could be saving x ammount of money in power if you use ArubaSwithes instead cisco switches for example as you can turn off the APs automnatically and turn them on again for example turn of at 10pm and turn them on again at 6am.
If i can tell them with Money numbers then they would understand... if i just tell them they would save energy they would just not consider this as they would think well i dont think its a lot of money so i dont care.
You get my point?
Cheers

Carlos,
Yes, understand the need. We can work on a document covering this.

Hello Madjali
those 12.5W is 12.5W per hour right?
The other thing that would be nice to have is
How much Energy i mean kWh would consume a switch with all 48 ports using POE and when its not using POE
and well the value of APS how much they consume in kWh
I guess if we get the kWh value we can all do our matematics and get how much savings you are getting.

Carlos,
I'm not sure I understand what you are referring to with respect to 12.5W.

Hello
What i want to know is how much kWh comsume an AP 105 for example
Also how much kWh consume a Aruba switch with POE on( imean all the ports using POE with aps connected to it using it)
And how much kWh comsumes a aruba switch with the POE off
Cheers
