Description

This fabric cooling module is a chassis component for the Arista 7816L 16-slot modular chassis in the 7800R4 series. It installs in fabric slot 6 and is aimed at AI/ML and HPC back-end clusters, large data centres and service-provider spine deployments where the fabric section needs dependable cooling.

The module contains 16 individually serviceable, hot-swappable fan modules, the highest fan count in the 7800 fabric cooling range (the 7812, 7808 and 7804 versions use 12, 8 and 4 fans). It supports graceful cooling degradation, so the chassis can keep operating if a fan fails, and it supports the 7800R4 front-to-rear airflow design. It measures 2.5 x 43.3 x 23.7 in (6.4 x 109.9 x 60.1 cm).

This module is used with the 7816L chassis only. It sits alongside DCS-7816LR4-FM fabric modules in slots 1 to 5, 7800R4 line cards and the DCS-7816-SUP1S, DCS-7816-SUP2 and DCS-7816-SUP2-N supervisor modules. Spare fan modules use part number FAN-7800-HS. No licence is required for this passive component.
