  • 4 versatile 1/10GbE SFP+ uplinks for flexible connectivity

32-port 40GbE QSFP+ switch for data-centre cores

The Arista DCS-7050QX2-32S-R delivers 32 ports of 40GbE QSFP+ connectivity in a 1 RU chassis. Four additional 1/10GbE SFP+ ports provide flexible uplink options. A dedicated RJ-45 management port and an RS-232 serial console port support out-of-band administration. The switch runs Arista EOS for programmable network operations.

Upgrade from earlier 7050QX models with less memory

This unit replaces the DCS-7050QX-32S by adding improved memory capacity for larger routing tables and richer telemetry. The jump is justified when existing 40GbE fabric switches hit forwarding-table limits or require enhanced buffering for bursty storage and AI workloads. Rear-to-front airflow matches hot-aisle/cold-aisle layouts without re-cabling.

Rear-to-front cooling frees front intake for dense

Two hot-swappable 500 W AC power supplies and four hot-swappable fans maintain rear-to-front airflow, leaving the front of the rack clear for high-density server intake. QSFP+ and SFP+ transceivers are not included, so procurement must match reach and fibre type. Rack-mount rails are also not included and must be sourced separately.

Questions about this item

What rack space does the 1 RU switch require?

The switch fits in a single 1 RU slot in a standard equipment rack.

How are the two 500 W AC power supplies and four fans installed, and what step is often missed?

Slide each power supply and fan module into the rear bays until the latch clicks; the step often missed is confirming the rear-to-front airflow direction matches the rack layout.

When will the hot-swappable fans or power supplies need replacement?

Replace a fan or power supply when the EOS dashboard reports a fault or airflow alert; both modules are hot-swappable so the switch stays online during the swap.
