Arista 48-port 1RU switch with SFP+ uplinks

This Arista Networks switch fits in a single rack unit and provides forty-eight 100/1000 Base-T copper ports for server or workstation connections. Six SFP+ ports deliver 1 or 10 GbE uplink flexibility. The unit ships with dual 500 W hot-swappable AC power supplies and four hot-swappable fans, all oriented for rear-to-front airflow. Arista EOS runs on the platform.

Who should deploy this switch

Network teams building top-of-rack or aggregation layers that need dense copper connectivity with a modest number of high-speed uplinks will find the port mix practical. The rear-to-front cooling design suits standard hot-aisle/cold-aisle layouts. Buyers who require Power over Ethernet, front-to-rear airflow, or a larger uplink count should evaluate other platforms.

The airflow direction decides rack fit

Rear-to-front airflow is the single specification that determines whether this chassis matches the data-centre cooling plan. If the cabinet expects front-to-rear cooling, this model will not align with the thermal design.

Questions about this item

Should I pick the 48-port 100/1000 Base-T model with six 1/10G SFP+ uplinks or a version with fewer copper ports?

The DCS-7020TR-48-R provides 48 RJ-45 ports at 100/1000 Mbps and six SFP+ uplinks that run at 1 or 10 Gbps, so choose it when you need maximum copper density plus 10 GbE uplink flexibility.

What does the 1/10G SFP+ uplink speed mean once the switch is racked and cabled?

Each of the six SFP+ ports accepts 1 GbE or 10 GbE transceivers, giving up to 10 Gbps per uplink for aggregation or core links while the 48 copper ports serve 100/1000 Mbps endpoints.

Which management interfaces are on the rear panel and what do they connect to?

The rear includes one RJ-45 100/1000 management port, one RJ-45 RS-232 serial console port and one USB port for out-of-band configuration and firmware loading.
