ZyXEL 24-Port Gigabit Ethernet Unmanaged Switch - Fanless Design with 2 SFP Ports [GS1100-24] 24-Ports

Got this in 2012, lasted 5 years in an open network cabinet. The ports started randomly stop working. Power cycle and then good for a little then same. Opened it up, power supply dying(PS capacitor leak) and not providing enough juice. I replaced the cap and it lasted 2 more years. I replaced the PS with an external wall wart good for 4 more years - but now it's happening again. I guess that's it. I was about to replace it with a Trendnet 16 port unit because it's the same dimensions/cabinet layout - but then thought otherwise because maybe they're off brand cousins of each other. So, I'm replacing it with a new Linksys 16 port unit. I've had a same model Linksys switch running in another network for the past 17 years without incident. Should have stuck with a Linksys from the start and paid the extra $30.

Size/footprint is awesome. Only came with 19 inch rack mounts.

I own about 10 ZyXEL products - mostly routers - and I have to say, I've had the best luck with their brand. I had a $150 Cisco that died days after the warranty expired, so I bought a previous model ZyXEL 16-port switch to replace it. That one performed flawlessly for 9 years. I bought this switch to replace that one when it died. When have you had any piece of networking equipment last 9 years? I have 4 ZyXEL routers that travel from location to location to set up temporary networks that serve large crowds and only one is starting to occasionally act finicky after about 8 years.

Ok.. I purchased 4 of these in late 2012. They work well, I had them on 24/7 under pretty heavy loads, no issues just plug them in and go. Now it is Aug 2015 by this time 3 of the 4 have failed. Out of warranty of course. All with the same symptoms. I should have trashed the first 2 but for some reason I just labeled them as bad and put them on the parts shelf. In a past life I was an electronic tech and when this last one went, I decided to take a look at them since each one seemed to fail in the exact same way. The first 2 within weeks of each other. They just simply stopped working all the standard port lights were out. But the 2 SFP and the power light were on solid. A recycle of the power (unplug - plug) did not change anything. This made me think it had to be a common component that was failing and I might be able to eyeball it. Clearly they were not production quality and never could be trusted again but maybe they would be good in a pinch if I needed a switch but did not have a good replacement on hand. Once I opened them up, what I found on for all 3 of the failed switches was that there were bloated capacitors on the power supply(PS). So I took a look at the output of the PS on one of them and it was 4.3vdc but the PS was labeled as 5v. I scrounged up some replacement caps. and replaced them. It was pretty easy to do, just desolder the old caps and put in the new ones of the same or better ratings. I put them in and tested. All fixed up. Next I ordered a few more caps from Amazon.Bluecell pack of 20, 16V 1000uF 105c High Temperature Radial Leads Replacement Aluminium Electrolytic Capacitor and fixed the other 2. You can see in the close up of the PS where the 3 closest Caps are all bulging at the top. and the ones in the back are flat. That is a sure sign of a cap that has seen better days. The other pics are just a good look at the inners of the switch. Note there are no fans. I also include 2 pics of one of the bad caps I removed. Hope this helps someone that might be thinking of purchasing theses. Or someone that has had a similar issue.
