Description

The Arista 7800R3 Series 48-Port 100GbE QSFP line card delivers high-density 100 Gigabit Ethernet connectivity for the Arista 7800R3 modular chassis, purpose-built for large-scale data centre and cloud fabric deployments. With 48 x QSFP100 ports and an integrated CPU, this line card supports advanced telemetry, stateful forwarding, and distributed control-plane processing — enabling intelligent, high-performance routing and switching at the chassis level. It is ideally suited for spine, core, and interconnect roles in hyperscale or enterprise data centre environments demanding terabit-scale throughput.

Designed as part of Arista's EOS ecosystem, the DCS-7800R3-48CQ2-LC integrates seamlessly with Arista's CloudVision management platform for centralised provisioning, streaming telemetry, and network-wide visibility. The onboard CPU enables local intelligence without relying solely on the central supervisor, improving resilience and forwarding consistency.

FAQs

Q: What chassis is the DCS-7800R3-48CQ2-LC compatible with?
A: This line card is designed specifically for the Arista 7800R3 Series modular chassis. It is not compatible with other Arista chassis generations such as the 7800R or 7800R2 without verification from Arista.

Q: What is the purpose of the integrated CPU on this line card?
A: The onboard CPU enables distributed control-plane processing at the line card level. This improves resilience and ensures consistent forwarding behaviour even under complex routing scenarios, reducing dependency on the central supervisor module.

Q: What transceivers are supported in the 48 QSFP ports?
A: The ports support QSFP28 100GbE transceivers, including SR4, LR4, CWDM4, and PSM4 variants. QSFP+ 40GbE modules may also be supported in compatible modes. Always verify optics compatibility with Arista's transceiver compatibility matrix.

Q: Is this line card suitable for data centre spine or core deployments?
A: Yes. The 48 x 100GbE port density and distributed CPU architecture make this line card well-suited for spine, core, and interconnect roles in large enterprise or hyperscale data centre fabrics requiring terabit-scale capacity.

Q: Does this line card support Arista CloudVision?
A: Yes. As part of the Arista EOS ecosystem, the DCS-7800R3-48CQ2-LC supports integration with Arista CloudVision for centralised network management, streaming telemetry, zero-touch provisioning, and network-wide analytics.

Q: Can I purchase the Arista DCS-7800R3-48CQ2-LC in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware specialist and can supply Arista data centre line cards including the DCS-7800R3-48CQ2-LC. Contact the team for pricing, availability, and configuration advice tailored to your deployment.
