Arista Networks DCS-7500E-36Q Data Center Switch

The Arista DCS-7500E-36Q-LC is a 36-port, 40 GbE QSFP+ line card for Arista’s 7500E modular data center switch family, enabling dense high-speed connectivity with 36 independent 40 GbE interfaces for spine/leaf aggregation in large-scale data centers. The module is designed for installation in a 7500E chassis and is specified with a power draw of 450 W typical and 556 W maximum, informing facility planning for power and cooling. It is documented in Arista’s modular switch literature as a line-card module (DCS-7500E-36Q-LC) alongside other 7500E line cards such as 72S-LC and 48S-LC, reinforcing its role within the 7500E ecosystem. The 36 QSFP+ ports support 40 GbE connectivity for uplinks or inter-switch links, contributing to scalable, low-latency data-center networks. Arista has published an end-of-sale advisory for the DCS-7500E-36Q-LC line card, indicating it is being phased out of the active product lineup; customers planning new deployments should verify current availability and consider alternative 7500E line cards to meet their port and speed requirements.
