How many 2500 Wireless Controllers Can I Have

[tparrettcisco]

I have 5 APs on my network being controlled by a 2500 controller.  I need to add another AP.  Can I add a second 2500 controller for additional APs?

Cisco 2504 WLC supports up to 75 APs.  If your current WLC only has 5 licenses you can purchase and install an 'adder' license (Additive Capacity Upgrade License) to increase the capacity of your existing WLC.  

Below is a link to the Cisco 2504 data sheet containing part numbers for adder licenses.

To add one extra license order either combination below, depending on whether you want e-delivery or paper certificate:

'L-LIC-CT2504-UPG' AND

'L-LIC-CT2504-1A' 1 Access Point Adder License for Cisco 2504 Wireless Controller (e-Delivery)

OR

'L-LIC-CT2504-UPG' AND

'LIC-CT2504-1A' 1 Access Point Adder License for Cisco 2504 Wireless Controller (Paper Certificate - U.S. Mail)

Note- the larger the license units the lower the cost, so buying 1x 25 unit license is significantly cheaper than buying 25 x1 unit licenses.

Hope this helps,

Pete.

+5 Peter !

I would only add if you go 50+ aps and you are looking to push some bandwidth you may want to consider a 5508 or flex connect your aps. Driving a lot of ap traffic to that little guy could impact low latency applications. 

Not just my 2 cents. But my own personal observation.
