I have some Cisco Router/Switch modules for sale. I'm not sure what to ask, so make me an offer on what you want and we'll go from there. (3) WS-C3900-ATMSC (3) WS-C3900-4RF (2) WS-G5482 (1000Base-T Gigabit GBIC Module) -- These have NEVER been used. Bought them for our 5500 but they're incompatible. James
