[FS] [US-ME]: 10/40Gb Arista gear

[bitbckt]

*** OFFERS ACCEPTED ***

I'm clearing out some 10/40Gb equipment, all lovingly used in my lab. I'll upload photos once I get a chance, but here's the rundown:

Item	Quantity Available	Price	Notes
Arista DCS-7050T-52	1	$300	Front-to-rear airflow. Running EOS 4.18.11.M. Comes with inner rails only; they function just fine as ears.
Arista QSFP-40G-XSR4	8 SOLD	$20 ea.
Arista QSFP-40G-SR4	4 SOLD	$10 ea.
Arista CAB-Q-Q-1M	5 SOLD	$10 ea.

FS QSFP 0.5M DAC	2 SOLD	$5 ea.	Arista coded.
Mellanox CX354A	4 SOLD		All have full-height brackets. I may have a couple of half-height brackets laying around, if interested in that instead; first-come first serve if I find them.
16GB DDR4-3200 RDIMMs	8 SOLD		SK Hynix P/N HMA82GR7CJR8N-XN.
Arista DCS-7050QX-32S	2 SOLD		Rear-to-front airflow. Running EOS 4.28.7.1M (32-bit). One has tool-less rack ears, the other has a new(!) pair of tool-less rails.

I accept payment via Wise, Zelle, and PayPal with a G&S invoice. Discounts on multiple item purchases and shipping to be negotiated on a case-by-case basis. I prefer USPS Priority on smaller items, and UPS on larger items.

All items are available for local pickup in the Portland, Maine area and shipping will originate there.

If you load it up with 48 active ports, yes it will need the fans running fast enough that you probably don't want it at home (you have 48x 10Gb copper ports at home, though? ) I used about two dozen ports at a time, and set it to 30% fan speed. I personally wouldn't sit next to it for an extended period, but it would be okay in a closet or basement. Obviously, this is a DC switch, not some Ubiquiti-class device.

At the load I ran it at, it was consuming about 200W. Maybe as high as 250W on occasion, but certainly no more than that. It's definitely less efficient than 1/10Gb SFP+ switching, but running transceivers to adapt to an existing copper cable plant is going to need much more than this option.
