Management features 1x 100/1000 port and 1x RS-232 serial console (RJ-45), plus USB, enabling flexible data center connectivity with wire-speed performance on all ports.

What is the switching performance of this switch?

The Arista 7048T-A provides 176 Gbps throughput, 132 Mpps forwarding rate, and 3-microsecond latency for 64-byte frames. With 40 Gbps uplink bandwidth and 768 MB packet buffer, it supports non-blocking Layer 2/3 forwarding, ideal for high-density deployments.

Does it support power redundancy?

Yes, it has dual hot-swappable 460W AC power supplies with 1+1 redundancy, operating on 100-240V AC at 50-60 Hz via IEC 320-C13. Typical power draw is 174W at 50% load, ensuring high availability without downtime.

What management features does Arista EOS offer?

Arista EOS includes Web GUI, SSH, Telnet, serial console, SNMP, Syslog, TACACS+, RADIUS, NTP, and ZTP. It supports IEEE 802.1D STP, OSPF, BGP, and Linux-based tools like VMTracer for automated provisioning and monitoring.

What are the environmental specifications?

Operates at 0-40°C, stores at -40-70°C, with 5-95% non-condensing humidity and up to 10,000 ft altitude. 1U form factor (19x1.75x16 inches, 17 lbs) with 4 N+1 fans and configurable airflow for rack efficiency.

Is the 7048T-A suitable for data center leaf-spine?

Yes, its 48x1GbE ports with 4x10GbE uplinks, 176 Gbps non-blocking throughput, and deep 768 MB buffering make it ideal for leaf layer server access, aggregating to 40 Gbps spine uplinks with low 3µs latency.
