Description

This Arista 7300X3 fabric module is a hot-swappable replacement or spare for the 7308 8-slot modular chassis. It suits data centre leaf/spine and Spline collapsed-tier deployments, as well as campus roles, where the chassis needs to keep every line card connected in a non-blocking fabric.

The module has integrated hot-swap fan modules and provides front-to-rear airflow. It delivers a full 6.4 Tbps of forwarding to each line card and is required in fabric slots 1-4 of the chassis. Fabric modules run active-active with graceful degradation, and the 7308 chassis supports over 50 Tbps of total switching capacity. Typical power draw is 380W with a 577W maximum, and the module weighs 17.3 lbs (7.8 kg).

It is intended for the Arista DCS-7308 chassis, including the DCS-7308X3 bundles, and works with the 7300X3 line cards DCS-7300X3-32C-LC, DCS-7300X3-48YC4-LC and DCS-7300X3-48TC4-LC, plus the DCS-7300-SUP and DCS-7300-SUP2-D supervisors. The 4-slot DCS-7304 chassis uses the separate DCS-7304X3-FM-F.

FAQs

Q: How many fabric modules does the 7308 chassis need?
A: Four. Fabric modules are required in slots 1-4 of the DCS-7308 chassis, and they operate active-active.

Q: Does this fabric module need a licence?
A: No, the module itself needs no licence. Optional modular-switch licences such as LIC-MOD-2-E are ordered separately at chassis level.

Q: Which line cards and supervisors does it work with?
A: It works with the 7300X3 line cards DCS-7300X3-32C-LC, DCS-7300X3-48YC4-LC and DCS-7300X3-48TC4-LC, and the DCS-7300-SUP and DCS-7300-SUP2-D supervisors.

Q: Can I use it in the 4-slot DCS-7304 chassis?
A: No. This module is for the 8-slot 7308 chassis. The 4-slot DCS-7304 uses the separate DCS-7304X3-FM-F.

Q: How much power does the module draw?
A: Typical power is 380W with a maximum of 577W. The 7308 chassis is powered by up to six 3000W power supplies.

Q: What airflow direction does this version use?
A: It provides front-to-rear airflow through its integrated fan modules.
