House wired with RJ45 and POTS eGrand "switch" can't get Ethernet
Posted on 5/30/22 at 9:42 am
Posted on 5/30/22 at 9:42 am
Thoughts on this?
I have that weird eGrand phone security box in my closet with the "device in" connector and maybe 8 ports.
There are about 10 cables with rj45 connectors on the ends.
If I connect them directly to *MY* switch the port doesn't light up.
If I run an Ethernet cable from my switch to that stupid phone box then plug one of the cables into one of the ports on it, it lights up and I can walk into the other room and see the device thinks it's got a wired connection but it won't work. I see the light on that end as well but no go.
Same for every cable in the closet. I plug into the POTS device and they show connection but I've tried every room in the house and they don't work. At least I can see it light up.
So, given that I have no idea what was actually done what is the most obvious culprit? Connector end wired incorrect on those cables? Wires crossed or maybe they didn't connect all the wires on the rj45 at one or both ends?
Looks like they didn't wire the place for Ethernet.. Just for shitty 1980s phone service but put in rj45 ports in each room instead of rj11. I don't want to pull new cable because this is between floors and that would be an ugly undertaking.
Should I just cut the connector off each end of the cable and crimp new ones?
What is the likely issue here?

eGrand? A Google search turns up nothing.
First look at the cable. Is it CAT5 or later? RJ45 connectors are fine. RJ11 would be going backwards in technology and you will never get a 1Gig connection with an RJ11 connector.
Lastly, Why not just go wireless everywhere?
ETA: You know POTS has nothing to do with Ethernet right? Those two are never going to be compatible.

Cad, I thought you were more technically inclined than this. Need to determine what kind of cable this is. Hopefully it is Cat5E as Cat5 only supports 100 meg.
Posted on 5/30/22 at 10:50 am to CAD703X
How many wires are connected to the RJ45 connectors?
If they used cat5 cable they don't need to land all the wires for phones to work. Also may want to check that the wires match the correct coloring for Ethernet.

Sorry I meant "legrand".
They are cat5e (see pics)

Looks like it was terminated as ethernet. That phone module isn't a switch though. Get rid of that and get a real gig switch.
Looks like you have some slack. I'd get a punch down block and terminate it. Would make things easier on you.
How many cable runs is it?

To answer your question I think it's about 6 or so runs. It goes to enough places in the house that I can add switches or pull it through the attic to add more. I just didn't want have to go between the first and second floors.

The switch you have in there isn’t an Ethernet switch at all. The traffic gets to it and goes dumb. It’s an analog telephone switch, not an Ethernet switch capable of sending digital traffic.

Your picture looks like they were terminated correctly.

I didn’t see a picture of what’s in the rooms. The Jack should have a label on it if you look (cat 5, cat5e, Legrand, etc). This is unlikely to be a problem, the problem is almost certainly you trying to run your Ethernet through a telephone switch.
Here’s the test you do:
It looks like you have an Ethernet cable from your switch to the box with 6-10 cables if I read your post right. Plug this into your 10g switch (which is an absurd thing to have in a house)
Get an rj45 male to male coupler, connect one cable to it.
I hope they’re labeled. If not, this is the fun part. Go room to room (or to the right one the first time) and plug in a (client) device. It should work.
If that’s the case, you need a real Ethernet switch in the room. 1g is plenty. 10g probably worthless since it is cat5e. You may be able to get 10gbE through that, but it’s not likely, and you likely don’t need it.
If you have power in there, that’s super easy.
If you do not have power in there, you want something that’s called “PoE pd”
This is a hard-to-find set of equipment (because when you search you find poe stuff and rarely “pd” stuff) that you can power over Ethernet (like a camera or a phone). I posted a thread on it a while back. Most of the responses were people ignoring that I named the standard and even provided a product that performed it. The only one I know of offhand is a $30 Flex Mini from ubiquiti. It’s only 5 ports, though (so you’d need two cables from your main rack to this room or to be less lazy than me and find an 8 port one. Unless you actually did have 10 ports in there). There are definitely some others. I think I had found a reasonably priced netgear 8-port one at one point before going another way.
There is only one PoE in with PoE out switch that (excluding passive standards. So 802.3a(X) stuff) I know of if you need PoE at your end points from an unpowered closet- that’s the Unifi Flex which is about $100. I don’t even know HOW to find/classify “PoE through.” The only other device I ran across with that is a Mikrotik Router (maybe something like 960 in the name), but it is a PITA product to begin with, and the documentation is fairly poor. My understanding is that it will deliver PASSIVE PoE at the voltage input to it (24 or 48v), so you can fry stuff if you don’t set the ports right. I, of course, never tested this. But I searched and didn’t find anyone explain even this much on those such devices.
Just as easy- “couple” all the ports like I explained above and pull them to your main switch (so run 6-10 cables to this weird box and use couplers. May be impractical)

Almost assuredly useless.

I'd check a keystone jack to double check. Most likely they didn't punch down all 8. Bypass the phone switch and plug it directly into your switch.

You can't run Ethernet through a telephone module.
Posted on 5/30/22 at 7:09 pm to philabuck
Yep. When I moved into my house I had RJ11 keystone jacks in every wall. But it was really just cat 5e. Just terminated it to rj45. Intercepted cable in my attic. Snipped it. Terminated it. Ran said cable to the new room I wanted to use as my network room.

I was simply pointing out that was the only way I could get the port indicators to light up at each end. Plugging directly into switch would result in no lights.

My FiL is in IT and dumps stuff off on me. I hated not to use it because it's super nice and also does PoE.

Where’s the router in all this mess?
Posted on 5/30/22 at 8:34 pm to VABuckeye
It's on the shelf above my rack. Awful coverage but I haven't tried to circumvent the fiber router with my own mesh yet.
Trying to get the hardwired stuff out of the way first.

Problem 1. Pretty sure that’s a managed switch.
Problem 2. See all the way to the right? Those are the inputs and they generally accept fiber SFP’s.
What’s the model number of the switch? If it is what I think it is it really isn’t an appropriate switch for your application. It certainly isn’t plug and play. What you want is a dumb switch.

We have bundled cable cable (2 cat5e, 2 coaxial) run to almost every room in the house. FOREVER I tried to get the Ethernet port in our upstairs living room to recognize our secondary switch with no luck. We'll a few months ago when trouble shooting it for the billionth time, I noticed a very small cut in one of the wires in the cat5e cable coming out of the box in the basement. The original installer cut it when they cut the sheathing when it was installed 20+ years ago.....

yet it worked fine at my old house and it works fine for all the other network cables plugged into the devices in the rack. how is this switch a problem? btw i have a pile of 6 port gig switches and i tried that as well with the same results as the HP.

Genuinely curious what issues you think I'm going to run into with this?
