Magnetic base saved my back too, wired a whole office lobby without touching a ladder once.

That "paragraph four" got me too, but I started screenshotting the policy and calling before I buy now.

Blame the vendor documentation on that one too. The new switch ships with VLAN 1 as the native on every port, and the old gear had been quietly forwarding untagged traffic on a trunk that someone set up back when Obama was president. I found six dead ports like that once because the old config had a vlan mapping that was never written down anywhere. Now I take a screenshot of the current switch state before I even pull the first cable, and I label every port with a Sharpie just in case. It's always the stuff nobody touched for years that bites you, not the stuff you actually changed.
