It is not unusual for me to find 10,000 Euro worth of networking equipment on my desk one day. It usually means that I have a long week of reading and testing ahead of me as I am the only person in the company, let alone building, that has ever seen or worked with these devices before. That means I am on my own aside from an Internet connection.
While your mileage may very, I’ve had the joy (and horror) of testing these devices as ‘drop in replacements’ to the test environment that we are using. In some instances, things just worked out of the box, however there are a few devices that needed to be poked a few times to get things moving.
