Arista DCS-7160-32CQ-R 32x 100GB QSFP100 Back-to-Front Airflow Switch

The 7160-32CQ is a 1RU high-capacity switch with 32 100G QSFP ports and no separate uplink ports, so every port can face servers, storage or the spine. Its 24 MB packet buffer is fully shared across ports.

Arista rates it at 6.4 Tbps and 2.4 Bpps, with latency from 2 microseconds. The control plane runs a quad-core x86 CPU with 8 GB RAM, expandable to 32 GB, and 4 GB flash. Power draw is 310W typical and 465W maximum.

Two AC power supplies are installed in a 1+1 redundant, hot-swap pair, using C13-C14 cords. Spares are PWR-500AC-R and PWR-500-DC-R for DC. Four hot-swap FAN-7000-R fans in N+1 move air back-to-front (port-side exhaust). Arista also sells the front-to-back version, so pick the one that matches your hot and cold aisles.

Management uses a 100/1000 RJ-45 port, an RJ-45 RS-232 console and USB. The switch weighs 19.2 lb. Advanced Layer 3 features such as BGP and OSPF need an Arista Enhanced L3 license, which is not included and is available from Arista partners.

Arista also sells the DCS-7160-32CQ-F with the opposite airflow. A new DCS-7160-32CQ-R is also available. Matching spares include the PWR-500AC-R power supply and the FAN-7000-R fan module.

This seller refurbished DCS-7160-32CQ-R is tested, working, and covered by the NetworkTigers one-year warranty.
