ColinM
thanks.
I cant believe that I was just about to throw this unit out and then I saw your post.
I haven’t replaced the caps yet but it is doing the same thing. I removed the PCB looking for any obvious issues and didn’t see any. The bulge in these caps is only small so didn’t raise doubt when first seen.
Can’t wait to get my gigbit switch back tomorrow.
Nice one. Thanks for taking the time.
Tony

Same problem, two bulged caos, replaced them with the 6.3V parts.
Back in business! Fifteen minutes total to fix the issue.

I had the problem with a GS108 and the flashing lights. When I opened the box, I could not identify any bulges on any capacitor. I replaced the two 1000 uf caps anyway. The switch does not work reliably. It will still go into flashing light mode unpredictably.

Any other ideas?

NETGEAR uses for routers,modems,switches,access points,repeaters shitty capacitors. Example: Teapo,G-Luxon,CapXon,Taicon and other crap caps.

We had exactly the same problems with the 8-port GS608 V2. Transfer speeds between connected devices suddenly dropped off the radar. Followed the instructions here and found two bulging capacitors inside that we replaced and hey presto – we’re back to normal! Thanks, very much for all the tips here – hugely appreciated :-)

Thanks. I was given a S108 that turned out to be dead. But thanks to you I got it up and running again

my gs108 died a year ago. it made . i had tried replacing the 6.3v caps but it didn’t help. i had taken one of the large diodes from it for another project.

today i ran into the switch in my box of junk. i stumbled onto two brand new 10v 1000 uf caps. i took a random diode that looked to be of the same size and dropped it into place. low and behold it powered up and linked to another device at 1gb!

the caps i originally tried may have been bad or the diode may have been bad. the project i was going to use the diode in didn’t work. i will test it some day to confirm.

lesson learned:
if you’re going to try and fix something, ensure the parts you’re using to fix it with are confirmed to work to spec. this applies to me trying to originally fix the gs108 with questionable caps and then me stupidly using the diode from the gs108 board which wasn’t working.

Just wanted to say thanks about the explanations about the capacitors, the tanks and the twice the voltage rule.

Those are great tips for hobbyist like me.

thanks

Mine would no go gigabit.
Replaced the caps. All good now.
Thanks a million!!!

Another success. Mine had been out of service for two years, and only lasted a month when I started to use it again.

Just to show how non-critical the cap values are, I took a flyer and dragged two *axial* (leads out the ends) antiques from my part stock. They’re 5000 mf at 6V, and US-made Spragues, so they have to have been born in the mid-seventies. There’s not much DC across them, so I “formed them up” with an AA cell for a few minutes, then discharged them, then trimmed the leads and sleeved them with 1950s nylon cambric tubing. The solder seems lead-free, so I had to prime the through holes with illegal 63/37 1070s solder to suck the excess out. Reamed the holes slightly with a fine dentist’s pick. Installed caps. Fit fine.

I now have the only gigabit switch that would qualify for an old-time radio museum.
