So that's why a 2 systems were getting crappy speeds. Yes, 2. It had been used only to split a single drop from another switch between two systems.
New drop, happy clients.
Some stuff here is museum material.
I don't see the issue here, it says Fast Internet Switch. Why would it lie like that?
Look, that's 10 times as fast as it could have been!
Fast Ethernet was great before gigabit
As someone who grew up with 10Base2 and 10BaseT, and thought 100Mbps was amazing - it still surprises me every time I'm reminded how slow it is now. I buried a cat6 cable out to my wife's studio and due to (I assume) some grounding issues it only syncs at 100Mbps - it works for general browsing etc., but every time we try to move some data it's arggghhh.
Shouldn’t be a grounding issue as you said that you buried it.
Can't find an emoji holding its side and laughing. Just pretend.
The phone lines repurposed as ethernet in my parents’ house also only do 100 Mb/s. I concur, so painful. I want to put a storage server there but no matter where it’s limited by awful speeds. It also means getting faster internet would be useless because it would be limited by these wires.
Fast ethernet ain’t so fast these days
What type of cable did you use? Water could have seeped into which cause a bunch of weird issue because the resistance on the wires goes all wonky. I’m not sure if you have access to a cable certified like a Fluke, but if you do I would use that to test and it will most likely tell you your issue. I highly doubt it’s a grounding issue because you’d issues like that in large buildings where the power is on different phases or technical power.
It's pre terminated pure copper direct burial cat6 from Amazon. I don't have access to a real tester, but my cisco switch has some built in test capability and I'm not sure I fully understand the results, but it's assessment of the cable length is pretty close and, more importantly, it shows all the pairs are the same as each other. I think that if there was some damage to the cable, it's unlikely that it would affect all the pairs in exactly the same way. I have other weird grounding issues - like 20V between neutral and ground, even though it's a new house and they're properly bonded at the service entry. I had a really old transformer on the street feeding the two buildings and the power company recently replaced it - I was disappointed when this didn't resolve all my issues.
That thing isn't even old. I had a similar situation occur recently. I found a 10meg 3com hub two months ago. Not 10/100 but 10meg. Not a switch but a hub. It was in a closet between two fairly new switches. I just chucked it not thinking it might be a conversation piece. We replaced the line with a 50m fiber run. We also replaced several drops since they were thirty years old. The customer was really happy with how fast things are now.
This one must be about 15 at least. Pre-dates me and I've been there for 13. Still functional so I'm at loathe to just sling it. Not fond of doing drops in such wonderful weather, in a building that is basically a dusty hot tin can. Wanted to do it properly though.
Just happy that on this side it's my direct employer and only one site. I'll have to do some more digging - I'm certain we have kit around even more legacy than this. The CNC lathe PC is y2k compliant....
That 3com hub was new in the late 90's
At least the lathe isn't running punch tape.
Don't upgrade or mess with the control. Disconnect from the network if it's on it. It should have RS-232. Throw a Pi or other SBC that does serial and a 12V level shifter; use that to feed it programs.
Also, make an image of the hard drive if it has one and start looking for a spare drive on ebay.
Woah. Haven't seen one of those for like 25 years. I used to bring one to LAN parties.
CS1.6, beige boxes, CRTs and sweat. A different time.
I'm imagining 2 server 2008 boxes with prod DB and reporting db?
Factory setting (says it all really).
A CAD PC and a standard client used by the QC guy.
Server 08 isn't a distant memory here though 😬
Air gapped, right?
Well, there was air in the gaps? We "volunteered" to move them onto a couple vms on server19 just so we could sleep at night.
It was fast for it's time.
It was fast enough up until today even!
Pretty sure my friend got one of those second hand for lan parties he hosted in highschool. That was was more than 20 years ago.
It's going straight in the "if you're looking in here, you must be desperate" spares cupboard.
I was troubleshooting why an upgrade from 10Mb Cards to 100Mb cards wasn’t working for a group of users. Tracing the lines and come to find out the existing lines were Cat-3…. that suddenly got splice in to a 50-pair telco bundle at a 66 block. Worked perfectly fine for 10Mb, not so much for anything faster.
We had a section of comptuers that would not properly image. Come to find out that there were actual cat 3 cables mixed in randomly across the floor. That was the year that I bought several hundred new ethernet cables and we replaced every last one of them to be sure.
I once found a old switch in a wall
When you tug the unusually weighted cable and you hear metal scraping in the wall 10 metres away 😬
Hope it wasn't too much of an arse to fish out. Or did you let sleeping switches lie? :)
"In the wall" is an exaggeration. It technically was behind a massive desk that tool a group to move.
Basically in a wall. At that same place I also found a consumer router and a switch in the ceiling handling everyones traffic. It was toasty up there.
Was it at least taped to the rack and/or wall?
I once found one in a network closet that had the entire bundle of cables going into it tied in a knot and was just hanging from the ceiling like that.
I am yet to see load bearing cat in person. Plenty time yet though!
What rack, haha.
Stuffed in a corner, under a load of other crap, in a warren of dust bunnies. Main rack is in an adjacent office.
I've used one of those before!
