Port power weird reading

[lacibaci]

I got five identical cameras that always showed similar power consumption. Lately, I noticed two of them are way off. The cameras work fine so I'm not sure if this is just an instrumentation error or the two ports are failing.

[sirhc]

It would appear the current sensors may have failed or were damaged.

I would RMA the unit for repair: viewtopic.php?f=6&t=1259#p9343

I power cycled the switch and here is the log. The switch is used to power 5 cameras and 1 Ubiquiti AP in a house (not business or tower)

Ask jakematic about how houses are not immune to power grounding issues.

Ask jakematic about how houses are not immune to power grounding issues.

Not sure I understand. If this was caused by some kind of grounding issue, this would be the first device (out of about 50) in my house to have such problem.
The switch is connected to a properly grounded (3 prong) outlet. All devices (5 cameras and 1 AP) are connected with shielded CAT6 cable...

Les is referring to my ground issue almost exactly a year ago. One that cost me $5k in new equipment and a lot of frustrations.

The problem may exist but never presented itself. Or at least the other equipment didn't have problems (yet).
The issue is the switch connects to something else over copper - giving you an alternate ground path (ethernet cable)

Long story short.. enough equipment was in jeopardy over so long a period that NON Netonix stuff was burnt to the point of dropping 90-ish vAC on the line and lighting everything up.
This tool, and a shock from a ToughSwitch case, helped me track it all down https://www.lowes.com/pd/Fluke-Digital- ... /999970846

Thankfully a Netonix switch helped me understand the issue and no fire was involved.


If you want the gory details, start here: viewtopic.php?f=17&t=1887&p=14633#p14633

Edit: To clarify - this is not a Netonix issue, or one cause by Netonix. It is simply the canary in the coal mine if you will.
My suggestion is to find/correct the issue(s), check all your equipment, and RMA the switch.

Surge suppressors do NOT protect against ground current. Never use Ethernet Surge Suppressors on "passive" POE switches

90% of all WISP equipment damage is from ground current which is a little bit for the average person to wrap their mind around, took me awhile. Ground is not Ground, there is what's called a ground potential difference and often Ethernet cables become a bond between 2 ground potentials.

Good resources but did I mention that all of my equipment is used in a house not commercially with different grounds or networks?

Should the proper usage of Netonix switch include a thick copper wire attached to the grounding screw and leading across my living room to the grounding plate?

If yes, than I guess I used it improperly just connecting to the "normal" (up to the code) house outlet. (It was actually connected to an APC UPS and then to the outlet)

I have to say, the responses here make me feel a little bit uneasy...

As was my situation.

Yes. Anything with a ground point on it should be used... they are there for a reason.
I use 12 gauge wire, and everything from the EdgeRouter to the Avaya IP500 telephony etc, are grounded. As are my UPSes.
Additionally electrical surge suppressors (line cord not ethernet) should be employed.

If yes, than I guess I used it improperly just connecting to the "normal" (up to the code) house outlet. (It was actually connected to an APC UPS and then to the outlet)

With a single 250W switch make sure your UPS is sized large enough to handle the inrush - 1500VA minimum, and the load is less than 50% (I like to stay under 30%)

I have to say, the responses here make me feel a little bit uneasy...

Was skeptical at first too and can tell you it does happen in residential settings.
Chris was fantastic at helping me understand the potential issues and how to resolve them.
I missed a funeral because I got sidetracked adding ground rods to my electrical entrance it was that important to me.
My 'up to code' residential install has such long runs and ground differential issues that unless a device is plugged into the same UPS/outlet it only connects to switches via fibre now.

I don't post much, but read this forum many times a day.
What I can tell you with almost 100% surety is that funky power readings on ports are due to ground problems. Ground is not ground....


By chance are any of the cameras outdoors ?
If so that adds additional protection requirements for ESD and ethernet properly terminated with metal connectors and a drain wire must be used.

[Julian]

I think the important takeaway there was that you should check out your house grounding yourself?

Contractors are notorious for skimping on grounding since you can't see it. Check for loose grounds rods that aren't bedded (like at sirhc's house), split bolts not tightened, broken continuity.. There is a reason that specific failure came to pass, and you can either accept what the combined 50+ years of experience in the field is attempting to tell you, or you can form your own opinion, one option may be significantly more expensive, in the long run.
