I’m an MSP who got tired of labeling cables every time I swapped a switch. I saw a tool like this once but couldn’t find it again, so I made my own.
This is a 12-port block. Each block is labeled for different-sized switches to help keep things organized. The model includes a bottom, but you can lower it into the build plate to print it open-bottom, making it easier to remove stubborn cables, especially with tight-fitting boots. I didn't bother adding port numbers as up/down and left/right numbering isn't exact an industry standard unfortunately.
Here's how to use it. IT'S SIMPLE!!!
1-Grab Block #1 and starting with ports 1-12 plug them into the same spot on the block that they were in the switch. if its a 24 port you will need blocks 1 and 2. a 48 will need all 4 blocks. Please use the correct block numbers to avoid confusion. If you have two cables, one in port 5 and one in port 45, use blocks #1 and #4. That's just an example as I'm sure nobody's memory is that terrible to need this tool in this circumstance. try to free the cables up as you go so they aren't binding later.
2-Move the blocks out of the way. with the cables in groups of 12 it should be easy to maneuver the switch out of the rack.
3-Slot in your new switch.
4-Remove each cable from the blocks and plug them into the same port on the switch making sure to cable manage as you go.
5-You've replaced a switch in a fraction of the time it would normally take.
