Forty-eight 1/10G SFP+ ports fill the front of the 7148SX, a 1RU switch for 10G server access and aggregation. Any port can act as an uplink, so the layout adapts to the rack design.
Arista rates the 7148SX at 960 Gbps and 720 Mpps, with 1200 nanoseconds of latency. Typical power draw is 600W. The control plane has 2 GB DRAM and 2 GB flash, managed through two 10/100/1000 ports, an RS-232 console and USB.
Two 760W AC power supplies (PWR-760AC) are installed in a 1+1 redundant pair, and five hot-swap FAN-7100-R fans in N+1 move air back-to-front (port-side exhaust). Arista also makes a front-to-back version of this switch, so confirm the airflow your rack needs and keep all fans matched.
The chassis measures 17.4 x 20.25 x 1.74 in. 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-7148SX-F with the opposite airflow. A seller refurbished DCS-7148SX-R is also available. Matching spares include the PWR-760AC power supply and the FAN-7100-R fan module.
This DCS-7148SX-R is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
