Description

The DCS-7816-SUP is the control-plane supervisor module for the Arista 7800R3 series, built for the 7816L, 7816 and 7812 chassis. It runs Arista EOS and handles all control-plane and management functions. One supervisor is required per chassis, and a second can be added for 1+1 redundancy. It suits large-scale data centre, cloud, carrier-edge and internet-peering deployments built on 7800R3 modular spine or core switch routers.

The module is powered by a 2.0 GHz eight-core x86 64-bit processor with 64 GB of system memory, 4 GB of flash and a 240 GB SSD. Management connectivity comprises one RJ-45 port and one 1G SFP port, plus an RS-232 serial console and two USB 2.0 interfaces. It draws 71 W typical (78 W maximum) from the chassis backplane. This non-Secure Boot version is distinct from the DCS-7816-SUP1S Secure Boot model.

This supervisor operates with the 7816L, 7816 and 7812 chassis only. The DCS-7800-SUP, SUP1A and SUP1S modules are intended for the 7808 and 7804 chassis. No separate licence is required to operate the supervisor itself, as it runs Arista EOS.

Enquire with XS Network Tech for new or used pricing and availability.
