This is a TP-Link TLSG101616 port gigabit, even switch which I of course picked out of a trash a couple of days ago. I do not know whether this thing came from I do not know why it was discarded but I figured we'd take it apart and have a look inside. It seems to be relatively recent actually. It comes apart like all over. I recommend you get a couple of screws, metal case, windboy with that. All right all the screws are eight so let's see what we got. This certainly won't worry. That's a proper big heat sink. This must be related to my current eight ports which because that also has a giant heat sink. No fan. Percival acualty. It might not have used much power. It doesn't seem to have any obviously bad caps in it so I might be of a this thing going to be coming back to life. Main fuse is okay. I haven't tried this thing actually. I don't know if it works. We've got a cap song. There. You know more caps on there. I mean it seems to be a hundred percent caps on the V-POW supply. I probably want some single 12-volt rail or something. We'll have the 12 volts two amps. We'll have a brand of this Qingjiang. It's a Chinese generic pay supply. Samsung's on the mainboard. That's a pretty nice surprise. Really nothing obviously wrong with this thing so let's just see what it does. Explosion hazard. Growing a what? It seems to be entirely dead. You're not a nice answer to pay supply so perhaps we do have a dead pay supply. It's not a millivolt coming out of that sea. The question is is it going to spring to life if we just pop this out with eights sticking our fingers in the mains. It's still dead. You're still dead so it seems like just got. I did pay supply this thing. That's nice news. Things generic enough to be very useful replaceable. Let's say just to power this device out of the well that is possible. Let's see if actual switchboards brings to life. All right I've gone with the wild assumption that red is going to be positive and black is going to be negative soon. Let's see what it does. Yeah. I've got some power. I've got an old deal now so I'd wager that boards. Okay. Yip stuck some networking into it and it seems to be working. Okay. Yip copying a proper gig of it speed for a hundred and something like a bicep a second. So we've certainly got a working switchboard and about pay supply so let's just pop it and see if there's anything obvious that wrong with it. Okay just had a quick perkybate with thing and it seems to have two very obvious issues. First of all I'd like to add to this little cap here the one by the C-Sync A for the 7 micro farad 50 volt seems to be entirely open circuit but it was surprisingly the primary cap V4 to 7400 also seems to be entirely open circuit according to my meter. So I'm going to have to desolder those and double check this one. It's very rare for the primary caps to go bad especially when they are probably 400 volt rated but this one's certainly going to be an issue. All right I replaced the two bad caps which are indeed obviously bad. I don't have as many really suitable for the 7 micro farad 400 volt caps so I just snagged one out of it and I will laptop power supply and it's a wee bit tall. It might require a few rounds of tape around the top in order to not be entirely unsafe once vacated on but it's a little do-you-for testing purposes. Now when V4 primary caps go bad things tend to get ugly so I wouldn't be surprised if this thing is toast but so we'll give it a go just to put it back there. I'll see. Okay maybe a truth this is going to go bang or this is going to go poof. Oh neither. Okay let's hook that back to this which. I'll still power that. And we've got a power LED. So I'd wager. This thing is going to work perfectly now. 100's own power. It seems to be talking. Oh we're going to be able to. I don't care of it rebooting. Can we? Yes we can. So there you go. That's a very quick and dirty T-peel in TLSG1016 repair and what I need to do is make sure that cap in there doesn't cause the fire or life hazard but there are few proper rounds of tape is going to take care of that. And if you're curious, you pay a consumption of this thing. It seems to be just about 7 or 8 watts with the internal page supply while it's transferring files with the lab PSU to make sure to about 300 milliamps say this internal page supply isn't particularly efficient since the 300 milliamps at 12 volt is about 3.6 watts. But you kind of have everything. It probably gets a bit more efficient on the high load when you actually put some more stuffing to the all of them holes right there. And yes I did replace all the caps. I wouldn't leave it to have had slack that. It's even got the protective plastics to the front. Oh yeah. Oh no. That's a good feeling. Terrier.
