Description
Description
The DCS-7816LR3-FM is a hot-swappable fabric module for the Arista 7816L 16-slot modular chassis in the 7800R3 series. It provides fabric switching for large data centre spine, core and router deployments, supporting up to 576 wire-speed 400G ports in the host chassis.
Six modules are required per chassis, installed in fabric slots 1-6. The modules run active-active and provide redundancy, with graceful degradation supported if a module is removed. A cell-spraying fabric delivers any port to any port connectivity with no drops. Each module has 16 individually serviceable fan modules for flexible, redundant cooling, with front-to-rear airflow through the chassis. Typical power draw is 1030 W with a maximum of 1331 W, supplied from the chassis backplane. The module weighs 32 kg.
This fabric module is for the DCS-7816L chassis only. It works with 7800R3 line cards and 7800 supervisors. It needs no licence of its own, although optional EOS licences apply at the chassis level.
