Mine arrived today and I'm actually quite impressed. It's in pristine condition and works as advertised. Seller reset it back to factory default so I had to configure access via the serial port. It has no web interface (except a paid one available from Arista), this is no big deal, I won't have to reconfig often and the OS is Cisco-ish enough that it won't be a big deal.
I'm curious if there is a way to unlock the web UI on these for home/lab users.

What helps a bit is shutting down the unused ports.

Just as an example.
This is a switch with:
10x 10Gbe (copper) ports connected and active rest of the ports are shutdown
4x 40Gbe (DAC) ports connected and active
Fans set to 60% speed

Code:
Power                                  Input    Output   Output
Supply  Model                Capacity  Current  Current  Power    Status
------- -------------------- --------- -------- -------- -------- -------------
1       PWR-460AC-R               460W    0.41A    7.12A    85.0W Ok
2       PWR-460AC-R               460W    0.39A    6.12A    73.0W Ok
Total   --                        920W       --       --   158.0W --

If I give all ports a no shutdown ( so making all ports active)

Code:
Power                                  Input    Output   Output
Supply  Model                Capacity  Current  Current  Power    Status
------- -------------------- --------- -------- -------- -------- -------------
1       PWR-460AC-R               460W    0.47A    8.25A    97.0W Ok
2       PWR-460AC-R               460W    0.45A    7.25A    85.0W Ok
Total   --                        920W       --       --   182.0W --
That is 24W difference just for shutting down some unused ports....

Yea, all 10G switches suck up gobs of power. i also have a 10G SFP switch I'm not using because of the power drain. This one I plan to use only as needed for large transfers. One thing on the plus side tho, is it's actually pretty quiet.
its funny, I checked generations of what we still have in prod 5820, no power details, 5920, 343 idle, 5930/5940, 100w idle so at some point someone figured out power had a cost :D

but darn they are awesome units.


what? arista has a gui?! never knew, always just use CLI, and LOVE their CLI.

interesting on shutting down the other ports now I have to try on my newer version of this switch

These numbers are why i still got mellanox sx6036 relics in top of my 2 racks.
8x 40Gbe + 20x sfp+ (breakouts from qsfp) and its not even at 50w.

That 10gbase-t consumption just looks OOF

There is no on-box GUI like Juniper with J-web on JunOS. Arista does offer CloudVision, but that's a pretty hefty service that you have to host internally on bare metal or your virtualization infrastructure (or pay for a cloud subscription). It provides a whole variety of config management and automation functions, as well as monitoring of streaming telemetry from the switches, but it's a beast and fairly complex to stand up in a homelab environment. Not to mention the licensing... ; )

I can live with the cli but the lazy side of me wants a gui. :p

I read that CloudVision (Arista management platform) uses honor based licensing but also "you will however break some EULA so after a while you need to pay up for the features you use. This also means that there are no licensing numbers to put in anywhere - the licensing is purely a paper product (and money moving from your wallet to Arista wallet).".

Can anyone chime in on this?

Also are these mountable to only 2 posts (in a regular 4 post rack) or are they too long for that?

Main thing keeping me from picking one is lack of OS availability, I think?

It's a bit heavy. I wouldn't mount it on 2 posts. I have mine on a rack shelf.

At work, I use 7280SR3s in a service provider network where most of them are mounted in 2-post racks. Arista includes ears intended for the purpose (which may or may not be included with used switches purchased elsewhere), but I would not recommend hanging the switches by ears mounted all the way forward. I attach the ears so they're about halfway back; the switches balance well around their midpoint, and I've never had a problem.

FWIW, there's a thread in the networking section where people looking for different EOS releases tend to congregate. You may want to ask there if there's something you're looking for...

my 40g breakout cable I ordered to test the 40G ports arrived today. They work as expected. So far no surprises with this switch. It's a keeper.
