I _think_ I am starting to understand what you are on about:

Are you saying that in a given rack you don't care that web_node_5007 went
into port 1 and web_node_5008 into port 2 before you replace the faulty
switch, whilst afterwards if they are arse-about because you can just throw
any ol server into any ol port (same firewall zone/VLAN/whatever)? Hence,
easier compared to this:

In which case you have to carefully make sure each cable goes back in the
same port it came out of, as when the config to the replacement switch is
pushed down it'll all obviously not work great if you've mixed it up from
where it was.
