The Arista DCS-7300X3-48YC4-LC is a switch line card from Arista designed for the 7300X3 series chassis. It features a modular form factor and supports 48 x 25 Gigabit SFP28 interfaces along with 4 x 100 Gigabit QSFP28 uplink ports, delivering high-speed data transmission capabilities.
This line card integrates into compatible Arista modular switches such as the DCS-7316 or similar systems within the same family. With its port layout of forty-eight downlink SFP28 slots and four uplinks via QSFP28 modules, it provides aggregation support in spine-leaf architectures or large-scale layer three switching applications. The unit utilizes front-to-rear airflow when installed in supported enclosures and derives power through the host chassis backplane connection without requiring independent PSU integration.
