Does anyone know if this network module works in all 2800s and 3800s?
My experience with network modules tells me the 2801 might not be an option but I can't find anything definitive on the website.
Has anyone seen this information?
There are no slots for Network Modules on the 2801 so no it is not supported in that model.
It is supported in the 2811, 2821 & 2851 -
