Lets say I have a forward facing switch, but all the server's NICs are rear facing. What is the proper way to get the CAT cables from the front to the rear of the rack in a way that doesn't open an air-flow hole(s)?
A patch panel seems like overkill to me, but let me know if I am wrong...
You'll probably want a brush strip. It sits below the switch and you feed the cables through it to the back of your servers.
Like that.
Install the switch in reverse. At the bottom, so it does not suck in the hot air from the servers. This is what I did - keeps your life a lot easier.
NO idea why people are not smart enough to also build back facing switches.
