Description

The Arista 7050S-52 is a 1RU data centre switch from the Arista 7050 Series, built for top-of-rack and cloud 10GbE server access and aggregation where low latency and low power per port matter. It runs Arista EOS and forwards Layer 2, 3 and 4 traffic at wire speed.

This SKU provides 52 x 1/10GbE SFP+ ports with no QSFP+ uplinks, 1.04 Tbps throughput, 780 Mpps forwarding and cut-through latency of 800 to 1150 ns. It has a 9 MB dynamic packet buffer, 128K MAC addresses, 32-way ECMP and a dual-core x86 CPU with 4 GB of memory. Dual 460W AC hot-swap power supplies run in a 1+1 arrangement alongside four N+1 hot-swap fans, with rear-to-front airflow. Typical power draw is 103 W and maximum is 185 W. It ships with the EOS base feature set, with optional licences for Enhanced L3, Virtualization and Monitoring and provisioning.

The SFP+ ports support 10GBASE-CR twinax, 10GBASE-AOC, SR, LR, ER and ZR optics, plus 1G SX, LX and TX modules. Spare parts include FAN-7000-R, PWR-460AC-R and KIT-7000.

FAQs

Q: Does this switch need a licence?
A: It runs Arista EOS with the base feature set covering L2 and L3 forwarding. Optional licences add Enhanced L3 (BGP, OSPF, ISIS, PIM, NAT), Virtualization and Monitoring and provisioning.

Q: What power supplies does it use?
A: It uses dual 460W AC hot-swap power supplies (PWR-460AC-R) in a 1+1 arrangement, accepting 100-240 V AC with IEC C13 inlets. Typical draw is 103 W and maximum is 185 W.

Q: Which optics and cables work in the SFP+ ports?
A: The ports accept 10GBASE-CR twinax up to 5 m, 10GBASE-AOC up to 30 m, and SR, LR, ER and ZR optics. 1G SX, LX and TX modules are also supported.

Q: Which way does the airflow run on this model?
A: This SKU has rear-to-front airflow, so the fans draw air in at the port-facing rear and exhaust at the front. Match it to your hot and cold aisle layout, and use FAN-7000-R for replacement fans.

Q: Does it have QSFP+ uplinks?
A: No. All 52 ports are SFP+ and there are no 40G QSFP+ uplinks on this model.
