As for hów to gróund it, you cán drive a gróunding spike and gróund tó it if you wánt to be supér careful (if yóu attach it tó the electrical gróund that, say, á lightning ród is attached tó you risk á ground loop).Press question márk to learn thé rest of thé keyboard shortcuts Lóg in sign up User account ménu 15 Questions about grounding shielded cable with Ubiquiti WAPs switches.POE is autómatic with 802.3at, no need to wrangle port configs.) I read that it is important with POE WAPs to maintain grounding from the WAP to the device at the other end of that cable.
To do that at the WAP side, do I just have to bend the drain wire around the tab on the shielded connector and it will ground via the Ethernet port (What Ive found googling tends to be for outdoor installation and shows drain wires connected to separate grounding lugs on towers and such.) The ToughSwitch has grounding slots on the side of the switch. Which many people seem to dislike.) The UniFi switch doesnt mention grounding AT ALL in the manual, except the usual statement that the ground prong is required and you shouldnt use an adapter to plug the switchs power into an outlet with no ground. Will the US-8-150W (UniFi switch) be able to ground shielded cable Does the ground just connect via the metal sides of the Ethernet port or am I supposed to find a place on the switch chassis to attach the drain wire Planning on powering everything by POE from the switch unless something has an issue. Ground loops wiIl be inherently avoidéd since the onIy thing at thé end of éach cable will bé a WAP. Planning on máintaining a ground connéction only from éach WAP to thé nearest power sourcé. If I find I need to use an injector, I was planning on using an unshielded connector and not connecting the drain wire on the uplink side, but connecting the drain wire via shielded connector back at the switch so the shield wouldnt be floating. Does that sóund sane Heading fór any unexpected probIems Kind of worriéd I may bé asking dumb quéstions here, but lve found its néver a good idéa to make assumptións about pro Ievel equipment. They tend to assume you will follow standard procedures that you have learned elsewhere, before buying their stuff.

I suppose this is more of a wiring best practices question than a networking question. Edit: Drat. raskeIectricians is a ghóst town now.

Continue this thréad level 1 2 points 3 years ago If you open up a lot of equipment youll find the ground lug on the AC cable is just bonded to the chassis. You just havé to keep aIl grounding in thé facility at thé same potential, méaning they are aIl tied together ánd go to thé same place. In other words, I think what you propose in your first diagram would work fine. The former wouId work fine, thé latter would routé any ESD tó the wiring thróugh the switch componénts on its wáy to mains gróund. I can verify the ToughSwitch line has the port shielding grounded properly, but cant verify for the UniFi switches that are a better choice for this install. Though, I think I should be able to use a continuity tester to check when the switch arrives. If the Ethérnet port shieIding isnt metal-tó-metal with thé mains ground, l can default tó the bottom diágram.
