Arista 7048T-A 48-port Gigabit switch

The Arista DCS-7048T-A is a 1 RU network switch providing 48 RJ-45 ports at 100/1000 Mbps and four SFP+ uplinks at 1/10 GbE. It includes a dedicated management port, a serial console port, a USB port, dual hot-swap 460 W AC power supplies and four hot-swap fans with front-to-rear airflow. Zero Touch Provisioning is supported for automated deployment.

Suited for dense copper access layers.

This switch fits environments that need high-density copper connectivity with 10 GbE uplinks, such as campus wiring closets or data-centre top-of-rack roles. Buyers requiring direct fibre connections on every access port or Power over Ethernet support should evaluate other platforms. The fixed port configuration also means the uplinks cannot be repurposed as additional copper ports.

Deciding spec: 48 copper ports

The combination of 48 fixed 100/1000 Base-T ports and four 1/10GbE SFP+ uplinks determines whether this unit matches the cabling plan. If the design calls for more than four uplinks, different uplink speeds or PoE on the access ports, this model will not meet the requirement.

Highlights

  • 1 RU form factor fits dense racks without wasting space
  • Dual 460 W hot-swap supplies keep the switch running during maintenance
  • Zero-touch provisioning automates deployment and reduces manual configuration time
