As pictured, up for auction is a used Cisco Systems Router WS-C2828-EN. I am not the computer savvy person.. so I have no idea how to go about testing this unit. It does light up.. but is not tested beyond that point.... therefore I am selling it "AS IS" with no returns. Shipping will be $ 14.00 to the lower 48 US states which does not include Hawaii or Alaska. thanks for looking.
