Description

The Arista 7130LBR is a 1RU Layer 1 Application+ switch for ultra-low-latency exchange trading, network visibility and monitoring, market data fan-out, tap aggregation and custom in-network FPGA applications. It combines a Layer 1 crosspoint, two Xilinx Virtex UltraScale+ VU9P FPGAs and an integrated R3-series L2/L3 switch chip in one chassis.

This 48S6QD-F model provides 48 x 10G SFP+ ports and 6 x QSFP-DD ports, each running 8 x 10G NRZ lanes for 96 x 10G lanes in total. Layer 1 latency starts from 4 ns at 1-10Gbps per lane. Each FPGA has 32GB of DDR4, and the R-series switch delivers 1.5 Tbps of throughput with a 4 GB packet buffer. An 8-core x86 CPU with 64 GB of DRAM and a 120 GB SSD handles control-plane tasks, and PPS SMA input and output ports support precision timing.

This SKU uses front-to-rear airflow with two hot-swap AC power supplies in a 1+1 arrangement and three N+1 hot-swap fans. It runs Arista EOS from release 4.30.2F and sits in EOS Feature License Group 4. The SFP+ ports accept 10GBASE-CR, AOC, SR, LR, ER, ZR, DWDM and 10GBASE-T optics as well as 1GbE SX/LX/TX, and the QSFP-DD ports accept 40G QSFP+ optics and breakout DACs.

FAQs

Q: What EOS licensing does this switch use?
A: It runs Arista EOS and belongs to EOS Feature License Group 4, with a minimum EOS release of 4.30.2F. Optional Group 4 licences include LIC-FIX-4-E for Enhanced L3, LIC-FIX-4-V for Virtualization, LIC-FIX-4-Z for Monitoring and Automation, and the FLX licences.

Q: What power supplies does the -F model use?
A: It uses two hot-swap AC power supplies in a 1+1 redundant arrangement with front-to-rear airflow. Compatible supplies are PWR-1511-AC (1500W, 200-240V AC), PWR-1511-DC (1500W, -48 to -60 VDC) and PWR-2421-HV (2400W).

Q: Which optics and cables work in the SFP+ and QSFP-DD ports?
A: The SFP+ ports support 10GBASE-CR, AOC, SR, LR, ER, ZR, DWDM and 10GBASE-T (up to 30m over Cat6a), plus 1GbE SX/LX/TX. The QSFP-DD ports run as 8 x 10G NRZ lanes and support 400G/200G/100G/50G/25G-CR breakout DACs and 40G QSFP+ optics.

Q: Can the QSFP-DD ports run at 400G?
A: No. The QSFP-DD ports operate as 8 x 10G NRZ lanes only. Breakout cables expose those lanes in different groupings but do not add higher-speed support.

Q: What spare parts are available for this chassis?
A: Spares include the FAN-7011H fan tray in front-to-rear or rear-to-front airflow, PWR-1511-AC power supplies, the KIT-7101-D, KIT-7101-RK and KIT-7101-LD-RK mounting kits, and the KIT-GND-EXT-1RU grounding kit.
