Question : Should a 568A to 568B Patch Panel run be changed?

I am the IT department for our small K-12 school.  I have done a lot of re-wiring over the last few summers and am pretty knowledgeable about wiring protocols and best practices.  I use the 568B standard exclusively, mainly because that was what was in place when I started.

The problem:  I had to add another cable to one of my top-layer patch panels last summer and discovered that both top-layer panels are wired to the 568A standard.   (I wired them.  I don't remember doing so and don't know what I was thinking, but I am the culprit.)  These two panels are absolutely the only 568A wired devices on the network.  I can't recall when I put them in, but it has been at least 3 years and I have not noticed anything that looks like a wiring-related performance issue.  

So my question is, "is this a problem?"   I have sort of an OCD need to fix it, but it will be a pain in the neck and I would just as soon not fix something that doesn't need fixing.  

My thought is that though everything still works, it might work better if I put everything on the same standard.  Is that correct thinking?

Answer : Should a 568A to 568B Patch Panel run be changed?

switches and many network devices automatically detect if they are on 568a or 568b wiring (this is often used as a way to detect switch>switch connections for example)

In many cases you wont notice if a panel is wired to the wrong standard, particularly if the patch panel in question is patched to itself or another device wired to the same standard.

If this panel is connected directly to something wired in the other standard then you may find problems.
This may occur if you patch one of the ports on a 568a panel to a port on a 568b panel, as this would connect the wrong wires together.

As you dont currently have a problem I assume most of the connections on the panel in this standard are either to network devices with autosensing or to items in the same panel.

Its good practice to maintain a single standard across your systems but it isnt a requirement and is unlikely to provide any particular improvements to your system.
