The 7048T is a 1RU top-of-rack switch with 48 100/1000BASE-T ports and four 1/10G SFP+ uplinks. Its 768 MB packet buffer is far deeper than typical gigabit switches carry, which helps with storage and backup traffic that arrives in bursts.
Arista rates it at 176 Gbps and 132 Mpps, with 3 microseconds of latency. The control plane has 2 GB DRAM and 2 GB flash, with two 10/100/1000 management ports, an RS-232 console and USB. Power draw is 235W typical and 325W maximum.
Two 760W AC power supplies (PWR-760AC) are installed in a 1+1 redundant pair. Five hot-swap FAN-7100-R fans in N+1 move air back-to-front (port-side exhaust). Arista also built the front-to-back version, so match the airflow to your hot and cold aisles.
The chassis is 17.4 x 20.25 x 1.74 in and weighs 22 lb, so check rack depth before installing. 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-7048T-4S-F with the opposite airflow. Matching spares include the PWR-760AC power supply and the FAN-7100-R fan module.
This seller refurbished DCS-7048T-4S-R is tested, working, and covered by the NetworkTigers one-year warranty.
