If you have two shielded patch panels in a U15 floor standing rack, is it OK to mount the patch panels to the rack that is painted. It seems like you are saying to not do that. So would you run a wire from one patch panel to the screw on the other patch panel, on the unpainted part, and connect the grounding plug wire to the same screw? The two patch panels are a little too far apart to use the included short ground wire to connect them together.
Hello William! Nope, don't do that. It is never a good idea to daisy chain bond like you are envisioning. You can mount the shielded patch panels to a painted rack, but the bond wires should be bonded separately. That all said, a simple way of going about this is to use TWO of our bond and ground adapters. Connect one to each shielded patch panel, replacing the stock bond wires, and then use two AC outlets to bond them to ground. That will greatly simply things, I think. There is a much more complex way of going about this using rack bus bars and secondary bus bars, but it sounds like your setup does not have that formal infrastructure to bond to.
if i have two shielded patch panels.. could i get two of these bond cables (one for each panel) and run them into the UPS in my rack? Or would it be better to just run them both directly into wall sockets, one socket per cable? I have both a PDU and a UPS in my rack (PDU connecting to UPS and then UPS to AC outlet) and I'd rather not have the bond cables leave the rack and just stay plugged in within the rack if possible. Appreciate any answers you can give!
The Bond & Ground Extension Wire Adapter is intended to be used only with a properly installed AC wall socket. If you bond the two shielded patch panels together, only one ground adapter plug will be required.
@@aliazimi91 Hello Ali! There are three ways you can go. You can either use a RBB (rack busbar) that is attached to your rack (wall mount or floor standing rack). A RBB is a copper bar that is bonded to ground on it's own, RBBs are typically connected to a SBB or Secondary Busbar that is mounted on the outside of your wall adjacent to your rack. The SBB is then bonded via a thick copper conductor back to your AC ground (directly into an electrical panel, structural steel, etc.). You would then bond anything in the rack that requires bonding to the RBBs. That would complete the chain of bonds to ground. This method is actually the correct method for commercial installs. It is costly due to the copper bus bars and hardware/tools. The second option, if the first one is not feasible, would be to use a copper bond wire from one patch panel to the other (making use of, or replacing the existing bond wires). You would then use a copper bond conductor that is attached to either of the patch panels that are daisy-chained together and then bond that conductor to ground. You could use our truePLUG adapter for that purpose. The last option is to use two separate truePLUG bond extension adapters and make use of two grounded AC outlets. That would mean both patch panels are bonded to ground but not in a daisy-chain fashion. Of the three, in a residential setting, the last one is the most effective, least costly, and least problematic.
Problem: I have to use a shielded ethernet because my ethernet needs to run next to a DC line in a robot umbilical line. I know this is not great practice but for our application, I can't put a few-inch gap between the 2 types. The issue I am facing is the ethernet is used for teleoperating the robot not internet access. So the ethernet plugs into the computer inside the robot, and the other side plugs into the ground station laptop. Since the ground station laptop doesn't have an ethernet port we are using a dongle (USB A 3.0 to ethernet). To my understanding this dongle won't transfer the ground from the RJ45 shielded ethernet to the USB port on the laptop. I am now to the point where I don't know how to ground the ethernet properly and worry the shielding will either amplify the interference like an antenna or just plain act like an unshielded cable. Do you have the slightest easiest advice? Ps I love your videos and your crimping tool lol. Thanks
Hello Zachary! Wow. I can see the issue. There really is no easy solution to this. You are correct that your cable shield won't be bonded to ground as it should be, but that does not mean you will automatically have issues either. As it turns out, more often than not an unbonded cable shield simply means the cable shield is not going to function. In very high EMI/RFI environments you *may* experience additional interference due to this, but it is on a case by case basis. Honestly, I would rethink this strategy you are using. I understand the need for the dongle, but you can bond the cable shield to ground well before the dongle. This is done by terminating the end of the shielded cable to a shielded keystone jack mounted into a shielded patch panel frame. The shielded patch panel frame is bonded to ground (and can be easily done with our truePLUG Bond & Ground Extension Adapter) and now you can even use an unshielded factory made patch cord from the keystone jack/patch panel to your USB dongle. I hope that helps!
Hello! We don't have a video that addresses that, but we do have a written blog with diagrams in our Cable Academy which details ground loops and how to avoid them. Here is the blog I am referring to: www.truecable.com/blogs/cable-academy/how-to-fix-a-ground-loop.
What happens if a computer is plugged in to another outlet and group which is grounded, and you also ground your patch panel on the other side, will this cause issues? At that point, I believe you're grounded at both sides on different groups. Isn't that going to create a ground loop?
Hello! You won't risk a ground loop unless those bond points end up at two disparate AC grounds. The potential for problems does not result from the number of bonds to the SAME ground, but when multiple different ground systems are involved. A good example would be bonding an Ethernet cable shield to ground at both ends in TWO different structures where they have their own AC ground systems.
If you have access to a formal bonding and grounding infrastructure or need to bond multiple accessories in a rack to a rack bus bar, then that is the direction you should go. truePLUG is an accessory designed to bond a singular accessory to ground (shielded patch panel for example) and further in environments that lack any sort of bonding and grounding infrastructure (like TRs that have racks with RBBs, and one or more SBBs in the room).
Hello! When (if) we starting selling our products internationally we will have multiple socket versions available. Right now it is NEMA standard since we sell in the North America and Puerto Rico only. Also, I don't recommend attempting to use a NEMA to G adapter as the resistance may increase and result in ineffective bonding to ground.
