You can, but that means punching down each cable just to identify them, a toner is the quickest way to do this. (cheaper ones do exist).

Sorry to jump in but what External grade cat6 cable do you people use? Plenty of choice for indoor networks like the OP is doing but very little choice for outdoor. I use Excel but it's expensive and finding it hard to find another recommended brand. Comms Express mentioned here have a brand called CE but sceptical.
I am after a few boxes of 305m. Different brands on eBay which I noticed but quality wise is a different matter.
So for 8 ports I'm looking at two double gang faceplates with four modules in each?If you want something mounted directly to the wall without any brackets use faceplates at both ends.
