if you've ever messed up a dimension or a hole position on something you're building, don't be too hard on yourself.

at least you're not the Cisco design engineer who caused an entire product line recall by placing the mode button (which resets the switch if held) directly above an RJ45 port.

Field Notice: FN - 63697 - Protective Boot on Certain Network Cables Might Push the Mode Button and Cause an Unexpected Reset on the 48-Port Models of Cisco Catalyst 3650 and 3850 Series Switches - Workaround Provided

Certain types of snagless Ethernet cables have protective boots that extend too far forward and above the plastic latching tab.When this type of cable is installed in Port 1 of any 48-port model of the Cisco Catalyst C3650 or C3850 Series switches, the boot might press and hold the Mode button, which invokes Express Setup and reboots the system. (Reference Figures 1 through 3 for illustrations of the issue.)Note: This type of boot-cable can partially obscure port LEDs, air vents, and USB ports.Figure 1. Problematic Cable before Complete InsertionFigure 2. Problematic Cable Completely InsertedFigure 3. Problematic Cable Completely Inserted (side view)

Just imagine the person who had to write this:

"Workaround/Solution
There are three options used in order to address this problem:

* Use a snagless cable with a less-pronounced boot in Port 1.
* Trim the boot on the cable that is installed in Port 1.

@13ma1 @thegpfury @mrgl @gsuberland file the reset switch back so it no longer protrudes and then cover it with tape.

@moresunshine @13ma1 @thegpfury @mrgl @gsuberland Option 4. Place a rj45 port blocker so no one uses this port ever. 😂

@thefern inb4 the port blocker comes with a protective boot

5. deactivate Port 1 in Software
6. deactivate mode-Button-Reset-Function as long as Port 1 is used (and plz. write it into the manual XD)
