I'd like to know if its possible to use non-arista DAC's from FS like the generic ones or Mellanox to save a few $?

I understand there was two methods to allow 3rd party DAC's however I can't find a definitive answer in this thread so I'm posted again.

I would like to use these for a Lab with some Chelsio T580 cards, does anybody have experience is this is reported working?
What kind of DAC cable? 10G, 25G, etc? I'm not sure what @pjackson issue was. I think DACs are different from SFPs and they might need to be Arista coded. My assumption is if you get those ones from Fiberstore you should be ok. FS is pretty good about RMAing if they don't work but you'll just be out of your time. If you have the "service unsupported-transceiver" command you should be set also but that may not apply to DACs because of how DACs work.

Also it could be as simple as pjackson plugged the DACs in before he issued that command, in which case you just need to re-insert.

FS-coded QSFP28 DACs work fine. At least, I'm pretty sure we got FS-coded DACs, trying to confirm that now. The switches are picky about non-Arista optical modules, but I think DACs are fine. The ones from Mellanox definitely work fine.

Anyone had success updating the switch up to 4.23.5?

Code:
localhost(config)#boot system flash:/EOS-2GB-4.23.5M-INT.swi 
% Software image flash:/EOS-2GB-4.23.5M-INT.swi is not compatible on this hardware

I have heard mixed things about the 2GB firmware. Have you tried the non-2GB firmware to see if that works on your switch?

We're using 4.23.1F 64 bit, according to my staff.

I'm told the 2GB model is only needed on the "non-S" revision of 7050QX-32. For the 7050QX-32S you should use the normal images.

It's strange, I've tried the 4.22 branch without success either:

Code:
localhost(config)#boot system flash:/EOS-2GB-4.22.1F-INT.swi
% Software image flash:/EOS-2GB-4.22.1F-INT.swi is not compatible on this hardware
I'll try with the normal images and report back.

Nice to hear... can I use the EOS64 images? There's EOS64-4.25.1F.swi available.

EDIT: I'm an idiot, you already said that you're using the 64bit release.

Well, that's also the 2GB image. Specifically which switch do you have?

Ha, I was just about to post exactly the same thing, as I just updated both of my switches to 4.25.1F, one 7060CX-32S and one 7050QX-32S, both with the EOS64-4.25.1F image.

Code:
arista>show version
Arista DCS-7060CX-32S-R
Hardware version: 12.00
Serial number: ***********
Hardware MAC address: ****.****.****
System MAC address: ****.****.****

Software image version: 4.25.1F
Architecture: x86_64
Internal build version: 4.25.1F-20005270.4251F
Internal build ID: fd5fd650-197c-40e5-b48c-b1e60cd70826

Uptime: 0 weeks, 0 days, 0 hours and 6 minutes
Code:
localhost>show version
Arista DCS-7050QX-32S-F
Hardware version: 21.32
Serial number: ***********
Hardware MAC address: ****.****.****
System MAC address: ****.****.****

Software image version: 4.25.1F
Architecture: x86_64
Internal build version: 4.25.1F-20005270.4251F
Internal build ID: fd5fd650-197c-40e5-b48c-b1e60cd70826

Uptime: 0 weeks, 0 days, 0 hours and 4 minutes
Incidentally, it also appears that the 2GB images are now EOL, see: End of software support for 7050QX-32 series - Arista . So that means the 7050QX-32 (no S) will no longer receive firmware updates, but the 7050QX-32S is still supported with the non-2GB images.
