FAQs

Q: Which Arista 7800 chassis is the DCS-7816-SUP1S compatible with?
A: The DCS-7816-SUP1S Supervisor1S module is compatible with the Arista 7816, 7816L, and 7812 chassis in the 7800R3 Series. It is specifically designed for these larger chassis configurations and provides control plane management for up to 16 line card slots.

Q: What is the difference between the SUP1S and SUP1A supervisor modules?
A: The SUP1S module features Secure Boot enabled for enhanced security and is designed for compatibility with specific 7800 Series chassis including the 7816 and 7812. Both modules feature 64GB of RAM and the same Intel Xeon Broadwell DE CPU, but the SUP1S provides additional security features for environments requiring secure boot capabilities.

Q: Does the DCS-7816-SUP1S support redundant supervisor configurations?
A: Yes, the 7800 Series chassis support 1+1 supervisor redundancy. You can install a second DCS-7816-SUP1S module for high availability, and Arista EOS supports stateful failover between redundant supervisors to maintain continuous operations during maintenance or failures.

Q: Is the supervisor module hot-swappable?
A: Yes, the DCS-7816-SUP1S is a hot-swappable component, allowing you to replace or install the module without powering down the chassis, provided a redundant supervisor is already active in the system.

Q: What management interfaces are available on the supervisor module?
A: The supervisor module provides dual 10/100/1000 Ethernet management ports including one RJ-45 and one optical SFP port for out-of-band management. It also includes a serial console port, two USB 2.0 ports for software updates or configuration transfers, and a clock input port for PPS synchronization.
