The 6148 should also only be used in the access layer, but should be purchased in favor of the 6348 today (the 6348 is outdated). the 6148-rj-45v module can be used for voice applications. The 6548 module is a 10/100 Ethernet module more suited for the network core, although I'm not sure what applications would be needed in the "core" (maybe at the edge for peering?) for 10/100 Ethernet. Possibly for packet capture devices run to SPAN/RSPAN -enabled ports? Other NMS devices??

I believe that Cisco also charges support on some fabric-enabled LC's, in particular - 16-port Gigabit Ethernet modules. You may see Cisco (as with other vendors) charge per LC on high-end platforms like the Cat6k, especially when feature-rich vs. feature-free modules are concerned.

Re: cat6500 ethernet module question [7:62063]
the 6348 has the ability to supply inline power to IP Phones and AP units.. The 6248 does not have that ability I am not sure about the 6148.

cat6500 ethernet module question [7:62063]
Hello listers, does anyone know the technical difference between the ws-x6148-rj-45 and ws-x6348-rj-45 modules for the cat6500 switches? the price difference is very significant though the documentation on Cisco's web site doesn't show any technical difference.
