NEW Arista DCS-7280SE-68-F 48x 10GB SFP+ 2x 100GB QSFP100 F-B Airflow Switch

The Arista DCS-7280SE-68-F is a 1RU 7280E switch with 48 1/10GbE SFP+ ports and 2 100GbE QSFP100 uplinks. Each uplink runs at 100G or 40G, or breaks out to four 10GbE links.

Capacity is 1.36 Tbps with forwarding at 900 Mpps, and Arista lists 3.8 microseconds latency at 64 bytes. The 9 GB packet buffer (3 GB per port group) is the standout, absorbing bursts from storage and leaf traffic. Layer 3 tables are smaller than on the later 7280R, 64K IPv4 LPM, 12K IPv6 LPM, 128K to 256K MAC/host and 96K ARP/ND.

Two hot-swap 500 W AC supplies (1+1) and four hot-swap fans (N+1) are included. Airflow is front-to-back (port-side intake), with PWR-500AC-F supplies and FAN-7000-F fans. Arista also sells the back-to-front DCS-7280SE-68-R; match the switch to your rack. Typical power is 263 W, maximum 405 W.

The switch weighs 22.2 lb and measures 19 x 20.6 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.

Arista also sells the DCS-7280SE-68-R with the opposite airflow. A seller refurbished DCS-7280SE-68-F is also available. Matching spares include the PWR-500AC-F power supply and the FAN-7000-F fan module.

This DCS-7280SE-68-F is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
