we currently have a AIR-CT5520-K9 with 200 AP license. We want to add another 5520 for redundancy. since these units are so expensive I have to get multiple quotes. So my issue is I am getting conflicting information from both vendors..
one says we need to get the AIR-CT5520-50-K9 with a minimum 50 AP licenses for it to work in HA mode.
the other says we need only to get AIR-CT5520-K9. no AP licenses needed..
then both wants to sell us 5X8XNBD NetCare. cant we get hardware replacement only?
thoughts?

You do not require licenses for the 2nd unit. Refer below
---
A. No. Unlike older controllers, 3504, 5520 and 8540 WLC can establish HA SSO even with only 1 AP license installed.
A. After establishing the HA, total number of licenses will be equal to the number of licenses on primary controller. After that, simply go to Management->Software Activation->Licenses in the web interface and add the additional amount of licenses you have purchased.
A. Example: One controller (intended to be primary) has 40 built-in licenses, the other (intended to be secondary) has 20 built-in licenses. Once you establish the HA SSO between them, built-in license count will be equal to the number of licenses on the primary controller, in this example 40. Simply add the remaining 20 licenses to the controller.

Regarding maintenance, you need to look at it, if you require RMA that in case of hardware failure. Otherwise you can go with this risk
