Is it possible to use the HWIC-2FE module into the 1841 SEC/K9 bundle? Using the online Cisco Dynamic config tool, HWIC-2FE is not listed as an option when you select the 1841. Does it mean that this configuration won't work? Thanks very much for your help!
Unfortunately the 1841 does not support the HWIC-2FE module. It only supports the HWIC-1FE module. See attached link for more details -
