Arista 7150 Low Latency Switches - Refurbished, Used, and New

Best Selling

Arista 7150S switches are 1RU ultra-low-latency 10G switches built for electronic trading, high-performance computing, broadcast and other workloads where every microsecond of port-to-port delay counts. They run Arista EOS, take 1G or 10G SFP+ optics in every front port, and the 64-port model adds four 40G QSFP+ ports for uplinks or breakout. Every chassis is offered in front-to-back (-F) or back-to-front (-R) airflow, and the -CL models add a precision clock for timestamping and PTP. NetworkTigers sells 7150S and 7150SC switches, PWR-460 power supplies, FAN-7000 fan modules and rack mount kits refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which Arista 7150 do I need?

Start with port count: 24 SFP+ ports for a small trading or HPC pod, 52 for a full rack of servers, or the 64-port model when you want four 40G QSFP+ ports for spine uplinks or 4x 10G breakout. Pick a -CL model if your application needs hardware timestamping or a precision clock; the plain 7150S-24 is the choice when it does not. Then match airflow to your rack: -F pulls air in at the port side and exhausts at the power supplies, -R does the reverse, and every power supply and fan module must carry the same -F or -R suffix as the chassis. Choose AC or DC power to suit your feed. Power supplies and fans are sold separately on some listings so you can choose the airflow and feed you need; each listing states what is installed.

Frequently asked questions

Do the 7150S power supplies and fans fit other Arista switches?
Yes. The PWR-460AC and FAN-7000 modules are shared with the Arista 7048, 7050 and 7100 series, so a spare bought for a 7150S can also serve those chassis, as long as the airflow direction matches.

Can I run 1G optics in a 7150S?
Yes. The SFP+ front ports accept 1G SFP optics as well as 10G SFP+ optics and DAC cables, which is useful for management links or slower devices in the same rack.

What is the difference between the 7150S and 7150SC?
The 7150SC models carry the -CLD suffix and are a variant of the same 24 and 64 port designs. Each listing states the exact model and airflow; ask us if you need to confirm a feature before ordering.
