Arista 7050SX2 128-port switch

The Arista DCS-7050SX2-128-R is a 2 RU data-centre switch that provides 96 ports of 1/10GbE SFP+ connectivity and 8 uplink ports of 40GbE QSFP+. It ships with Arista EOS, two 750W hot-swappable AC power supplies and four hot-swappable fans, all configured for rear-to-front airflow.

Network teams needing dense 10GbE access

This switch suits network teams that need high-density 10GbE server access combined with 40GbE uplinks in a 2 RU chassis. It is not for buyers who need 100GbE interfaces, Power over Ethernet, or a 1U form factor. Management access is provided through two RJ-45 10/100/1000 ports, one RJ-45 RS-232 serial console port and one USB port.

96 SFP+ ports and 8 QSFP+ uplinks

The decisive specification is the port layout: 96 SFP+ ports running at 1 or 10GbE and 8 QSFP+ ports running at 40GbE. Rack mounts are not included, so compatible rails must be sourced separately. The unit includes two 750W power supplies and four fans, all hot-swappable with rear-to-front airflow.

Questions about this item

What does the 10GbE SFP+ interface cap the 96 ports at in practice?

Each of the 96 SFP+ ports runs at 1 or 10 Gbps depending on the transceiver fitted; the hardware does not exceed 10 Gbps per port.

What physical space and mounting hardware does the 2 RU chassis require?

The switch occupies 2 RU in a standard 19-inch rack; rack-mount brackets are not included and must be sourced separately.

How are the two 750 W AC power supplies installed, and what step is often missed?

Slide each hot-swappable PSU into the rear bays until it clicks; the common miss is not verifying the rear-to-front airflow direction matches the four fan modules.
