Arista DCS-7010T-48-DC-R | 7010T 48-Port Gigabit Switch, 4x 10G SFP+, DC PSU

Q: What deployment scenarios are ideal for the DCS-7010T-48-DC-R?
A: This switch is purpose-built for data center top-of-rack deployments serving 1GbE servers, out-of-band management networks, and IPMI/iLO connectivity. Its DC power supplies make it suitable for telecom and critical infrastructure environments requiring -48V DC power redundancy.

Q: Does this switch support Layer 3 routing protocols?
A: Yes, the 7010T-48 supports advanced Layer 3 features through optional software licenses, including OSPF, BGP, IS-IS, and PIM. The base configuration provides full Layer 2 switching with wire-speed Layer 3 forwarding capability.

Q: What is the power efficiency compared to similar switches?
A: The 7010T consumes approximately 52W typical power draw, translating to less than 1W per port, making it significantly more efficient than typical gigabit switches that consume 100W or more. The DC model supports redundant DC power supplies for high availability.

Q: Can the airflow direction be changed?
A: Yes, the 7010T features a reversible fan module that can be rotated to provide either front-to-rear or rear-to-front airflow without powering down the switch. The -R model ships configured for rear-to-front (cold aisle) airflow.

Q: What optics are compatible with the SFP+ uplink ports?
A: The 4 SFP+ ports support a wide range of 1G and 10G optics including SR, LR, and direct attach copper cables. High-power optics such as ER, ZR, and DWDM are not supported due to the switch's low power design.
