Hi, I am using 7210 controller and AP93
I have 6 AP93 in one location, so i need to set 3 of them 2.4 and the other 3 to 5Ghz

Regarding the first 3 they worked 2.4 witout any problems, regarding the other 3 I added a new AP group for them and in the VAP I choosed (a only), but they are inactive and even ointhe 2.4 band (in Monitoring Tab).

What shall I do to force it to use 5 Ghz only

Another question, in the ARM I modified the minimum EIRP to be 18, but still some of the AP93 access points are working with 16 dBm, while other models are working fine.

The APs that are operating below the TX power, did you take a look at the ARM profile attached to the AP-Group of the APs with the issue?

Regarding the problem of the single radio, it has been solved (Thanks)

regarding TX Power, I did the follwing test

I added 3 X AP-275 & 3 X AP-93H & 3 X AP-93 to the same AP Group and set the minimum TX to 20 dBm

All the AP-275 and AP-93H used 20 dBm While AP-93 one used 16 dBM and another used 17 dBm while the third used 20 dBm !!!!!!

There is a max TX for the G radio and one for the A radio.  Make sure that you change both if you want to set the minimum to 20.

Do You mean 802.11a Radio & 802.11g Radio under RF Managment (I already changed them)  

If ARM is enabled (default) the min TX values from the radio profiles is/are ignored in favor of the min TX values inside the ARM profile which itself is 'attached' within the radio profiles. See attached image.

But make sure that both the arm profile used in the a-radio profile as well as the arm profile used in the g-radio profile is set to what you want.

They are the same in both profiles
I think, its something related to AP93, as AP-275 and AP-93H both worked normally in the same AP group

even I thought that the AP-93 can't support this TX power, but already one of them reached it

Please use the command "show ap allowed-max-EIRP ap-name <name of ap> country-code <country code>"

That is to find out what is the maximum EIRP for each channel for that AP in your country code.

I will do,

But I think it is not the problem as one of them already reached 20 dBm

Yes, you are right
only channel 6 can support 20 dBm 

It the first time to know the the max TX power can be different between different channels

Thanks

Okay.

Use the "show ap config ap-name <name of ap> | include EIRP" command.  That will tell you the current max and min EIRP and where it gets it from:
