I did support for inexpensive, but commercial grade network equipment. I'd just been promoted to a senior support engineer 2 days earlier. My boss came to me and said "we have a customer who just deployed a over $250k of equipment and it doesn't work. The customer, sales person and account rep are on the call, we need you to figure it out". After an hour or so going over their setup we found out our new switch connects to a 3com switch over a fiber line. 3com was out of business at this point, but I managed to find documentation on the product online. It's fiber ports were FDDI. Our switch only supported Ethernet (No one really supported FDDI at this time.) At which point the sales person said "we'll just have to replace the rest of the hardware" and the customer agreed.
