So, three for three..

The last one I think lived a hot life. There was a lot of white dust inside and parts of the black plastic PCB covers were starting to crumble. I blew out the white dust and then felt oddly energetic and focused.

Anyways, after the PSU replacement it booted right-up. Seems to have come from the same place. Config had lots of VLANs. This one started at 2000 and I stopped around 3500.

Thank you once again fohdeesha for your wealth of knowledge and to everyone else who contributed to this thread!

White dust and focus, now that's a hypothesis.

That might add up to the assumption/hypothesis that maxing out the POE usage will lead to running the PSU near its rated load, thus the resulting heat/insufficient passive cooling might be the cause of early PSU failure? Would be nice if one could cram a 40mm fan in to prevent future failures if running at more then several POE devices. Of course, that sort of kills the part about being solid state/silent. Just something to move air over the PSU with a very low noise rating would be a good idea. But to find something that will run at ~50V? might be tough for a 40mm.

If anyone does not need all the ones you have obtained please shoot me a PM.

All 6 have to be flipped. The entire connector needs to be reversed.

If you're not sure about this I would suggest sharing a photo before you plug it in. You will damage something if this is done wrong.
So that's the pin order for the original PSU, 3 black, then 3 white, with the clip facing away. So I just need to swap all three white and black wires, right? Does order matter?

Correct. Order of the individual back or white wires does not matter. All of the black wires are the same. All of the white wires are the same.
Here's some more photos you can compare against with the new PSU installed.

Why not just swap the board connectors? Just get a small flat screwdriver and gently pry up. The one on the new PSU will probably break (all three of mine did) but we’re not using them anyways. Just work the fasteners side to side up the pins and then place in the correct orientation on the new board.

this way, you maintain the correct latch.

Mine just showed up. Power supply is dead with similar symptoms - the output voltage overshoots to ~65V in 40ms and then the supply goes into some kind of protection mode. I ran it up on a bench supply and it powered up no problem.

It looks like the seller might be getting greedy with those 56V power supplies; my $30 (and $35) offers were auto-declined.

Hmm, seller came back with a $60 offer for that SL Power PSU. Anyone got a good alternate source on an open frame supply?

Yeah he did get greedy. I didn't get away with $35, but he did accept $45 a few days ago without countering. I wonder where he got them; same part on Mouser is over $100.

Someone on Reddit mentioned using a FSP 54v 2.2A unit that happened to end in a 4 pin ATX plug, I think these might be it: Lot of 5x FSP Group FSP120-AWAN2 Sparkle 54v 4-Prong Power Supply 2.22A | eBay

So you wouldn't hit the 130W the original is rated for. But apparently it works.

The $40 price is achievable for a new SL Power PSU, the main challenge is the MOQ (160).

BTW, if anyone who is still in the repair stage with a bench-adjustable PSU, can you check if these guys will power up and run with proper POE delivery on 50.4V ? I did see a couple of open frame MeanWells that can be adjustable.

I was doing some reading and I would feel that folks who will be running a bunch of APs/POE devices on these guys might want to consider a higher powered PSU for it.

Looking at the datasheet for several of these open frame supplies show a derating of 33% running convection below 40 degrees Celsius.
Above 40 degrees to 60, there's a somewhat linear drop from 33% to just over 66%.

For example, if you're running this fella at 50 degrees Celcius,115v, the PSU is only rated for 50% load, meaning they only put out 1.16A at the above parameters. With high drain - running a lot of POE devices, and left hot, the 2.32A PSU is probably just going to be hung out to dry in a year or two.

For those that are running a couple of APs/CCTVs should probably be fine.

I've been able to get a source for NOS Gospell G0493s (G0493 250W for PoE Switch with CB CE-Open Frame Power Supply-Shenzhen Gospell Digital Technology Co.,Ltd.-Shenzhen Gospell Digital Technology Co.,Ltd.) which put out 3.4A via convection or 4.4A fan cooled. Same form factor and connectors.

I would expect costs to run ~$45-$55 + ship.

Yes, this places it in approximately the same price range as the eBay one, but this has significantly higher rated power (@ convection) and thus might prove to be more long-lasting given the above derating.

Let me know if anybody is interested. If there is enough interest i'll organize a bulk buy of sorts.

Unfortunately, mine shuts the POE ports down right around 50.6 volts. After the voltage is brought back up the PoE comes back online.

I did notice that on the original power supply there are some crispy components on the daughterboard on the output side near the optocoupler. Looks like a small SMT resistor and a small three-pin IC that is probably a MOSFET got too hot. Not the kind of failure mode I expected and might be evidence of overvoltage on the output. Otherwise the power supply looks like quite a nice unit, heavy heatsinking and well built.
I tested a license upgrade (license install perpetual 1 2x10gr). It applied immediately and I was able to get the SFP+ ports to come up with a Cisco DAC after configuring their speed for 10g-full (they came up at 1gbit by default; perhaps from having been configured that way when it was licensed as 2x1G). This seems like a pretty nice switch so far.

You do seem to be correct that many open frame power supplies have significant derating. However, the spec sheet for this specific PSU claims there is no derating at least up to 70C. Here is a link to the spec sheet: https://assets.alliedelec.com/v1553162720/Datasheets/ac954dc0fc6bc8a2394c8c1f2c657ea9.pdf

I also find it interesting the PSU should be able to handle short duration loads up to 200 watts at 50C. This also makes me wonder if the PSU is basically the same as the LB240S which has the same 130 watt output rating at 70C (and looks strikingly similar visually).

Adding to everyone else's success stories, I also purchased 3 of the switches and 3 power supplies. All 3 switches are running well with the 130 watt PSUs recommended by fohdeesha. Unfortunately, 1 of the 3 power supplies I received does not maintain it's voltage when plugging in any POE device, so the POE shuts off moments after plugging the device in to the port. I expect a replacement of that power supply will rectify the issue.

I'm guessing the PSU can actually put out a bit more if you give it some airflow, but they probably derated it for convection and conduction applications. This batch of broken units probably had the unfortunate task of running a full 12 port POE AP load and was probably stuck in a riser somewhere convenient. I'm guessing most of us would be running them in a bit more friendly environments, so hopefully they will outlast the PSUs this round.

Picked up several of the 3.4A/4.4A Gospower units, so hopefully those should last until the next 40G upgrade.

Thought for sure I had burned out my first attempt because I pulled the clip connector from the old PSU, put it on the new, but didn't flip it (whoops). Unplugged, fixed the stupid, plugged it in and it booted!

Got my SL Power PSU in. One of the PCB corners was bent upwards, but only the mounting hole is in that location, so I suspect it'll be fine. I might see if the seller will send me another one, delamination is a long-term kind of issue. It does power up and run. This is a live-heatsink design (The OEM one wasn't, but most consumer supplies are), so be sure to use the insulating plastic above and below. I didn't bother to switch any pins around, if you apply enough force to the retention plastic on the PSU side it flexes out of the way and you can plug the connector on with the right polarity.

I also found this while surfing around for rack mounting parts:
RUCKUS ICX7150-C12P-2X1G Switch L3 Managed 12 -Port 7150-C12P | eBay

Bit more of a gamble as the price is doubled but it could still be a deal. Sounds like the same symptoms.

Just to add to the success stories. Finally got my devices that were sat at my offices for over a month and swapped out the power supplies. 2 Switches done . 2 successes.

It may have been answered already, and if it has I apologize... Are there different versions of this switch with 1Gb/10Gb SFP+? Or they're all the same and it's only a matter of license? Thanks in advance!

I haven't gotten mine fixed yet, still waiting for my PSUs this week, but from reading, it's a honor system. You simply enable the license.
