The 7048T-A is a 1RU top-of-rack switch with 48 100/1000BASE-T ports and four 1/10G SFP+ uplinks. Its 768 MB deep packet buffer helps it ride out bursts from storage and backup traffic without dropping frames, a common problem on shallow-buffer gigabit switches.
Performance is 176 Gbps and 132 Mpps with 3 microseconds of latency. The control plane carries 4 GB DRAM and 2 GB flash, managed through a 100/1000 port, an RJ-45 RS-232 console and USB. Arista lists power draw at 174W typical and 212W maximum.
Two 460W AC power supplies are installed in a 1+1 redundant pair, with PWR-460AC-F as the spare. Four hot-swap FAN-7000-F fans in N+1 move air front-to-back (port-side intake). A back-to-front version also exists, so keep every fan and supply matched to the rack's airflow.
The switch measures 19 x 16 x 1.75 in and weighs 17 lb. 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-A-R with the opposite airflow. A seller refurbished DCS-7048T-A-F is also available. Matching spares include the PWR-460AC-F power supply and the FAN-7000-F fan module.
This DCS-7048T-A-F is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
