Arista DCS-7816-SUP | 7800R3 Supervisor Module, 64GB, Dual Management Ports

Q: Which Arista chassis models are compatible with the DCS-7816-SUP?
A: The DCS-7816-SUP is compatible with the 7812, 7816, and 7816L chassis of the 7800R3 Series modular switches. Each chassis supports two supervisor slots for redundancy.

Q: Can I run a 7800R3 chassis with only one supervisor module?
A: Yes, one supervisor module is required to run the system. A second DCS-7816-SUP can be added for 1+1 redundancy to provide hitless failover and continuous operations.

Q: What management interfaces does the supervisor module provide?
A: The DCS-7816-SUP includes a serial console port, dual Gigabit Ethernet management ports (one RJ-45 and one SFP optical), two USB 2.0 ports, and a clock input port for precision timing synchronization.

Q: Is the supervisor module hot-swappable?
A: Yes, the DCS-7816-SUP is hot-swappable and accessible from the front of the chassis, allowing for field replacement without powering down the system when redundant supervisors are deployed.

Q: What operating system runs on the supervisor module?
A: The DCS-7816-SUP runs Arista Extensible Operating System (EOS), which handles all control plane functions, routing protocols, system management, CloudVision telemetry, and advanced data center features.
