Description

The Arista 7800R3 supervisor module is the control-plane engine for the 7804 and 7808 modular chassis in the 7800R3 series. It runs Arista EOS and handles all control plane and management functions for the chassis. Each chassis has two supervisor slots, so a second supervisor can be fitted for 1+1 redundancy.

This module is built around a 1.9 GHz six-core 64-bit x86 processor with 64 GB of system memory and 4 GB of flash storage. It draws 61 W typical and 72 W maximum, supplied from the chassis power supplies. It measures 2.1 in x 9.0 in x 17.25 in (5.3 x 22.8 x 43.8 cm) and weighs 6.3 lbs (2.9 kg).

It is designed for the 7804 and 7808 chassis. The 7816 chassis uses different supervisor variants, and the SUP1A and SUP1S are sibling modules for the same chassis, so confirm the part number against your chassis before ordering.
