If we're going to ground both ends of the run, let's make sure we're not making a significant ground loop. I don't know nearly enough about the electrical service at Omni to have an opinion on whether a ground loop is likely, and I'm definitely not a pro at this kind of thing, but I think if you stop just short of hooking it up and measure the current through the drain wire, as long as it's reasonably low you're in good shape. I don't do a lot with shielded twisted pair though, so if I'm confused, please correct me. :) -- Charley Sheets

Mark, can we get a cat6 at least?

TERMINATING: CAT6A its a pain, I only have done it once. And now that I just watched this video (linked below), I see that that time I did it not quiet right. Cabling imho seems easy, but has a lot little things to look for; for example" degree of bending, cover toxic or not, gauge, distance, grounding, no reg staples usage, if possible a few inches away from electrical cables, untwist as much as possible when terminating, peeling down cable w the string to avoid cutting internal cables. :) anyways.. fun stuff. No to mention to have patch panels and connectors of the same category (5e with 5e; Cat6 with Cat6). Oh yeah, and grounding. Article about GROUNDING and a video about how to terminate a CAT6A Shielded Connector: This guy (George1421 <http://community.spiceworks.com/people/george1421>) seems to know what he is talking about. Good info besides of what I am pasting here. http://community.spiceworks.com/topic/433095-how-to-set-up-grounding-for-sh… "Normally you don't need STP (shielded twisted pair) cable unless you are in an industrial environment. In a business or home application there isn't the RFI that causes signal noise. With that said, if you want to use STP (older name for F/FTP) cable, you only connect the drain wire (grounding wire) on one end of the cable. If you connect both ends you could create a potential ground loop if the devices on either end of the link are connected to different power sources (mains). Normally you would ground at the switch end of the link. You will need special STP jack and plugs. Both have a metal shell to conduct any electrical noise to ground. You can tell if your device supports STP grounding by looking at the jack to see if there is a metal grid around the jack, if it is metal then you can get the ground from there. Also the STP jacks have a metal conductor around the outside of the jack. You typically need to ground only the long runs. Using STP cable between the wall jack and the device offers little protection." "When you setup your wiring plant be consistent with your grounding. When we install STP cable we always ground on the upstream device. For example on the runs between the MDF to IDF closets to wall jacks we ground at the MDF for the link to IDF. and then earth ground at the IDF to the wall jack (remember I said to earth ground only one end of the cable). Also you need to make sure your devices have an earth ground in the power plug. Some electrical devices have a floating ground design for the power plug. In this situation you will have to earth ground the device chassis (there should be a earth ground lug on the back of the device). Here is an OK video on terminating a STP jack http://www.youtube.com/watch?v=5s65RTjtUic " "Finally, the multiple ground paths comes into play where you may run the STP between building and those buildings are powered from different mains which may have different ground plains (grounding levels between earth ground). If this is the case you will have current flow through the drain wire of your network cable (not a good thing). This is why you should only ground one end of the drain wire. If you are networking inside one building with one power main then you should be safe from ground loops (as long as all of your devices are earth grounded)."
