Hasivo Switch DAC Support ?

Without more measurement it'll be hard to figure out what's what. It's possible it's 1.8v instead of 3.3v or maybe it's something else (i.e. not enough pull up or pull down). Since they have the RS232 chip fitted, does the other side of the chip result in different serial traffic?
Finally got a terminal after shoving a networking jack in place and using a usb/RJ45 'console' adaptor. Baud was 28800 for some gorrang reason.
Fun things of note; the chip at the bottom is a *knockoff* Max232 chip. You could hook into TTL if you solder on the TTL side, but the other side is RS232 with the fun +/- voltages which explains some of the reasons I was having issues.
Got into uboot using the default mfg password and now trying to bring up the network.

For anyone playing along at home, finally got it working by pulling the firmware, finding the linux image section of the code in hex, rewrote it with a good copy of the firmware and then reflashed.
No, I was able to get an ok uboot RS232 terminal over a plastic RJ45 socket I put there temporarily.
You could probably get ttl off the other side of the MAX232 equivalent, but I cbf'd to solder into the PCB for fear of damaging something.
Uboot was useless on this model, though, as there's no commands compiled in. It's just good enough to tell if it's booted correctly or not.

The SW600-5GT-2S+_SE works fine and tests at 9Gb/s+ with the following:
Sounds good, thanks! In the setup I'm currently considering, the switch would be used solely with DAC cables in terms of the SFP+ slots.
I purchased the L3 version of this switch which has the console port. The firmware version is a little older but the only disadvantage of lacking of English language support. Does any one have the English version of this firmware or know if the one mentioned in this topic is compatible?

Yeah, I saw that one and wondered what the difference was supposed to be between the two besides the console port.
Regarding the firmware, my understanding is that they will send the latest firmware to you if you contact them on AliExpress and ask for it.
Oh wow very interesting, I wonder wheter it's the same realtek chip in there.
If it's the case you could probably crossflash and turn the non l3 into a l3 switch.
You would have to take the heatsink off though or check via uboot.
AFAIK there is also ongoing work to make it openwrt compatible which would be insane.

Did you manage to get an English language firmware from Hasivo?
If not, there is another brand on AliExpress named POEPLUS selling the exact same switch. You might be able to convince them to send an updated firmware if Hasivo doesn't come through for you.
Thanks for the tip, I might give this a try. No nothing from the vendor so far. Would be good to understand from others here which version of firmware is currently shipping. Mine is as follows:Did you manage to get an English language firmware from Hasivo?

I tried the S600WP-5GT-2SX-SE (5 port 2.5Gb with 4 POE, and 2 SFP+ cages, managed). Showed up and POE does not work. Disabled in WebUI and attempting to enable always fails. Will be seeing if the Aliexpress return process even works.

I assume that you tried PoE on all the different RJ45 ports?
I'll have to make sure to test it on mine too then, which I haven't gotten around to yet.
EDIT: Thankfully, PoE works on port 1-4 on my unit. That matches what they saw when reviewing it and it also matches the pictures from the product page on their website, so I assume that's normal. It doesn't match what is printed on the box though, so I might still mention that to Hasivo so that they have a chance to correct it if they want.

I just tried with that DAC and it won't link with my Intel X710-DA2 on either switch port.
Did you have to do anything special to make it work?
What were the cable lengths of the DACs that people tried?
I noticed by doing a loop test that my switch successfully negotiates a 10G link using my 0.5 meter H!Fiber DAC, but not the 2 meter DAC cable of the same model. In essence, it seems like it might have an issue with cable length.
EDIT: I ended up using the ipolex 10GBase-SR transceivers in the end too, and they do indeed work.
Note that just they are manufactured by 10Gtek, so it might be basically the same as the 10Gtek branded one. The same is true for the H!Fiber DACs.
One thing I noticed is that the Hasivo switch doesn't properly show the temperature of the transceivers even though they report a temperature when I check with ethtool when connected to my NIC. They definitely run hotter in the switch than in my NIC though, so I'm much more interested in the temperature of the one in the switch.
