Frequently asked questions

What is the total switching capacity and port density of the DCS-7500R-36Q-LC?

The DCS-7500R-36Q-LC delivers 1.44Tbps of full-duplex wire-speed switching capacity with 36x40GbE QSFP+ ports and 6x100GbE QSFP100 ports. Each 40GbE port supports flexible breakout to 2x25GbE or 4x10GbE, enabling up to 96x10GbE total density. This non-blocking architecture ensures simultaneous wire-speed forwarding across all ports with 8GB packet buffer.

How does the DCS-7500R-36Q-LC support multiple speeds and breakout configurations?

The line card supports 5 speeds (10GbE, 25GbE, 40GbE, 50GbE, 100GbE) through flexible optics and cable combinations. Native 40GbE QSFP+ ports can breakout to 2x50GbE or 4x25GbE when populated with appropriate optics. The 6x100GbE ports provide native 100G connectivity. This flexibility allows operators to optimize port allocation for diverse workload requirements without hardware changes.

What redundancy and high-availability features does this line card provide?

The DCS-7500R-36Q-LC integrates with the 7500R chassis architecture featuring dual supervisor module redundancy, N+1 fabric module redundancy, and N+1 fan module redundancy. The modular design supports grid and power-supply redundancy with AC/DC power options. Advanced monitoring includes LANZ for microburst detection, sFlow (RFC3176), IEEE 1588 PTP, and CloudVision integration for proactive management.

Which chassis platforms support the DCS-7500R-36Q-LC line card?

The DCS-7500R-36Q-LC is compatible with three modular chassis: DCS-7512N (12 line card slots), DCS-7508N (8 line card slots), and DCS-7504N (4 line card slots). All chassis support dual supervisors, 6 fabric modules, and multiple power supply slots. The line card plugs in from the front while fabric modules and power supplies insert from the rear, utilizing a passive midplane architecture.

What are the power consumption and environmental operating specifications?

Typical power consumption is measured at 25°C ambient with 50% load on all ports. Operating temperature range is 0-40°C with storage temperature -40 to 70°C. Relative humidity tolerance is 5-90% non-condensing. Operating altitude up to 10,000 feet (3,000 meters). Front-to-rear airflow design optimizes cooling efficiency in data center deployments.

What monitoring and telemetry capabilities does the DCS-7500R-36Q-LC support?

The line card supports comprehensive monitoring via LANZ for microburst detection, sFlow (RFC3176) for standard telemetry integration, IEEE 1588 PTP for precise time synchronization, and CloudVision for centralized management. Advanced Event Monitoring and VM Tracer VMware integration enable real-time visibility into network performance and virtual machine traffic patterns across the fabric.

How does the DCS-7500R-36Q-LC compare to the newer 7500R3 series line cards?

The DCS-7500R-36Q-LC is part of the original 7500R series with 1.44Tbps throughput and 8GB buffer. The newer 7500R3 series delivers significantly higher performance with 230Tbps system throughput, supporting up to 36x100G ports per line card or 72x50G ports. The 7500R3 uses advanced Jericho2 chipsets and supports denser 400G/100G configurations, though the 7500R-36Q-LC remains suitable for existing deployments and cost-sensitive applications.
