Arista DCS-7800-SUP | 7800R3 Supervisor Module for Modular Data Center Switch

Q: Which Arista chassis models are compatible with the DCS-7800-SUP supervisor module?
A: The DCS-7800-SUP is compatible with all 7800 Series modular chassis, including the DCS-7804, DCS-7808, DCS-7812, DCS-7816, and DCS-7816L. Each chassis supports two supervisor slots for redundancy, though only one supervisor is required for operation.

Q: Does the DCS-7800-SUP support redundant supervisor configurations?
A: Yes, the 7800 Series chassis can house two supervisors simultaneously. While operations require only one supervisor, installing a second DCS-7800-SUP provides redundancy with hitless failover capability, ensuring continuous network operations during maintenance or supervisor failures.

Q: What management interfaces are available on the DCS-7800-SUP?
A: The supervisor module provides one serial console port for direct CLI access, two Ethernet management ports (one RJ-45 and one optical), two USB ports for software or configuration updates, and one clock input port. It supports CLI, SNMP, Syslog, and industry-standard APIs for network management.

Q: How long does it take for the 7800 Series switch to boot with the supervisor module?
A: Arista modular switches with the DCS-7800-SUP typically take 15 to 30 minutes to boot completely. This boot time allows the supervisor to initialize the control plane, establish communication with fabric modules and line cards, and prepare the system for network operations.

Q: Can the DCS-7800-SUP be hot-swapped during operation?
A: Yes, the DCS-7800-SUP is a hot-swappable module. In redundant configurations with two supervisors installed, you can remove and replace a supervisor without disrupting network operations. Always ensure at least one supervisor remains operational during maintenance.
