The Arista DCS-7280SR2K-48C6-M-R is a 1RU 7280R2K large-route switch router with 24 1/10/25GbE SFP25 ports, 24 1/10GbE SFP+ ports and 6 100GbE QSFP100 uplinks. Breakout allows up to 12 50G, 48 25G or 72 10G interfaces in total.
The K designation means larger route scale, 2M IPv4 LPM and 1.4M IPv6 LPM entries with 768K MAC addresses. It is only sold as -M, meaning 32 GB DRAM plus an SSD, not MACsec. Capacity is 2.88 Tbps and 835 Mpps, latency starts at 3.8 microseconds per Arista, and the packet buffer is 4 GB. AlgoMatch and accelerated sFlow are supported.
Two hot-swap 750 W AC supplies (1+1) and four hot-swap fans (N+1) are included. Airflow is back-to-front (port-side exhaust), using blue-handle PWR-747AC-BLUE supplies and FAN-7000H-R fans. Arista also sells the front-to-back DCS-7280SR2K-48C6-M-F, so match the rack. Typical power is 215 W, maximum 370 W.
NEBS compliant, it weighs 20 lb and measures 19 x 16 x 1.75 inches. Advanced Layer 3 features such as BGP and OSPF need an Arista Enhanced L3 license, which is not included and is available from Arista partners.
Matching spares include the FAN-7000H-F fan module.
