The Arista DCS-7280SR3K-48YC8-F is the large-route 7280R3K version of the 48-port 25GbE switch router. This 1RU unit has 48 1/10/25GbE SFP ports and 8 100GbE QSFP100 uplinks, which also run as 8 40G or 16 50G, for up to 80 25G/10G interfaces.
Route scale is profile dependent, reaching up to 3950K IPv4 routes in L3-XXXL or 2850K in L3-XXL, with up to 384K MAC addresses; the L3-Host-XL profile supports 192K ARP entries. Capacity is 2.0 Tbps (4.0 Tbps full duplex) at 1 Bpps, Arista lists latency from 3.8 microseconds, and the packet buffer is 4 GB. MACsec is on separate SR3MK models, not this SKU.
Two hot-swap 500 W PWR-511 AC supplies (1+1) and two hot-swap fans (N+1) are included. Airflow is front-to-back (port-side intake), with PWR-511-AC-RED supplies and FAN-7011M-F fans. Arista also sells the back-to-front DCS-7280SR3K-48YC8-R, so match your rack. Typical power is 154 W, maximum 324 W.
The switch weighs 20.2 lb and measures 17.3 x 18.38 x 1.72 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-7011M-F fan module.
