Check the difference between 38x 1 AP Adder Licenses or 1x new Cisco AIR-CT5508-HA-K9. I would recommend a SmartNET contract to download and update your WLCs to at least 8.2.166.0: https://software.cisco.com/download/release.html?mdfid=282600534&softwareid=280926587&release=8.2.166.0&rellifecycle=ED&relind=AVAILABLE&reltype=all

Hi Ciccio,

the second one needs at least 50 AP licenses to convert to a HA SKU unit. I think rebuying a HA SKU 5508 directly will be cheaper but check it first.

[…] already posted a tutorial about Cisco WLC HA with 5500er series but I want to show you how to configure an N+1 high availability system with 2504 WLC from Cisco. […]

In reply to nakamurra. I've had this happen when the primary lost a static route that we had made for service port access. The secondary still had the same route. Added the route and everything was back to normal.

To place them on two locations for example. Or you don’t trust the ha system and have two WLCs so you can bring all APs to unit 2 and can update unit 1 without problems.

I understand. but for this question ?

And what is the reason to buy 2x controllers with 50 ap on each ? For what ?

In reply to Adi. Not really, you can point the first half of your APs to the first controller and the second one handles the others. You can place two standalone controllers in different locations (I had a customer with two WLCs placed in different towns). A HA cluster needs to be in one place (because the dedicated link needs jumbo frames between them).

For load balancing perhaps ?
