1552E not able to connect to the WLC

[francisp]

We purchased cisco AIR-CAP1552E-A-K9 and it has IOS c1520-k9w8-mx.124-23c.JA2. WLC with the lastest firmware 7.0.116.0 is not able to connect to the Cisco 1552E. 1552E log show that it can see the WLC but unable to connect. We have devices for both U.S and Australia domain.

Why are the 1552E not able to connect to the WLC?

Let me try and will let you know the result.

Thank You,

I was going through other forums and found that it  is not possible to change the regulatory domain because regulatory domains are written on to the EPROM in the AP.

Thank You,

We have a secondary WLC which is not being used. Can we configure this as secondary controller with only one regulatory doamin and use for mesh devices ?

Thank You,

Francis:
Yes you can.

However, If APs on different WLC's can hear each other then the RF groups may not be formed although same RF group name is configured on two WLCs.
For RF-Groups to work among multiple WLCs it needs same countries to be configured on all WLCs with same order. see multiple countries guildlines:
http://www.cisco.com/en/US/docs/wireless/controller/7.0/configuration/guide/c70lwap.html#wp1147755

If your 1552 APs are not on same location as othe APs on the other WLC (each WLC has its APs in different locations and APs from first WLC do not hear signals from APs on second WLC) then you can do it safely by dedicating one WLC for the mesh APs while that WLC is configured with one country only.

5760 WLC does not support 1552 APs. it doesn't support all outdoor mesh APs (1500, 1510, 1520, 1530 or 1550).
