I think the patch should be split into two tags: patch-panel and something to refer to patching a computer, perhaps software-patch would be a good name (I'm open to other options, though). Or, patch could refer to software patches, and a new tag, patch-panel is made for rack-mounted patch panels.
Here's my thoughts: Looking at the first few pages of questions for it, it refers to one of two things: patch panels (like for a server rack) and patching a computer (applying an update to fix something). The highest voted questions are about software patches, but there are also some questions about patch panels. Both are on-topic here... but they are two different things. The patch tag currently has no usage guidance, so a new tag should get some.
