How do I know if my APs are running 4x4:3 or 3x3:3 mode?

[RabbitSF]

We have the 5508 controller with the 3702i APs. Is there a command to run from the CLI or a page from the web console that shows the MIMO information so that I know if it's running 4x4 or 3x3?

Thanks much!

Depends on the PoE draw of the AP.  If the AP gets the recommended PoE+ power (20w) then the AP runs 4X4:3.  If the AP draws only 15.4w then 3x3:3.

I know what you said. But I am asking if there is anyway to tell (or see it) if it's running 4x4 or 3x3 when the AP is connected to a PoE+ port. Thanks!

If the power draw is 20.0w then it's 4X4.  Period.

I was curious too. I just discovered the differences in power this morning and found at 15.4 watts it was 3x3. Then I found buried somewhere that with controller code 7.6 it's 2x2 so I wanted to verify this. I'll be going to 8.0 soon which says it is 3x3.

Hello,

This might help you. I wrote about the power and antennas not long ago.

Thank you for commenting with this. Exactly what I was looking for and I verified I am running on 3x3. After going back to the 7.6 reference and 2x2 I found that is on the 2700 and not the 3700.

Perfect. Can you kindly mark this thread answered. It will help others with their search and allow me to catch up with Leo on POINTS!
