What types of WIC exist in cisco?

Question

System administration

Please tell me what types of these slots exist, and how you can distinguish them by markings. At the moment I want to buy a Cisco 2801 or 2811, and the question is, can I add ethernet ports?

Answer 1

Documentation from the site Cisco.com
And probably this article will be interesting (in short, either one 2-port board or two 1-port boards). There are restrictions on the pieces of iron there and they are also painted.
