Arista DCS-7130-96S-R | 7130 Connect 96-Port 10G SFP+ Layer 1+ Switch, 2U

Q: What is a Layer 1+ switch and how does it differ from traditional switches?
A: Layer 1+ switches perform bit-for-bit forwarding with full signal recovery and regeneration at the physical layer, with no buffering or packet processing. The DCS-7130-96S-R forwards data between ports in just 6 nanoseconds, making it ideal for ultra-low latency applications like high-frequency trading, while also providing packet-aware statistics and comprehensive management capabilities.

Q: What applications are best suited for the DCS-7130-96S-R?
A: The DCS-7130-96S-R excels in applications requiring deterministic, ultra-low latency including remotely configurable patch panels, one-to-many data broadcast, network tapping and monitoring, ad-hoc packet sniffing, media conversion between different optical types, and signal regeneration for long-haul connections. It is commonly deployed in financial trading networks, network visibility architectures, and high-performance computing environments.

Q: Does this switch require any software licenses?
A: The DCS-7130-96S-R runs Arista MOS (Management Operating System), which is included with the hardware. MOS is Linux-based and provides CLI, web interface, SNMP, JSON-RPC, and other management protocols. Unlike traditional switches, Layer 1+ devices do not require feature licenses for forwarding functionality.

Q: What types of optics and cables are supported?
A: The 96 SFP+ ports support a wide range of transceivers including 1G and 10G SFP/SFP+ modules, long-range multimode LRM optics, passive and active direct-attach copper cables, and various fiber types. All ports support speeds from 100Mbps up to 11.3Gbps with automatic speed negotiation and full signal integrity.

Q: Are power supplies and fan modules included with the DCS-7130-96S-R?
A: Yes, the DCS-7130-96S-R comes with 2x redundant 460W AC power supplies and 3x hot-swappable fan trays configured for rear-to-front airflow. The R suffix indicates rear-to-front airflow direction, which is important for proper data center hot aisle/cold aisle cooling design.
