Power Consumption of Aggregation Switch S10506

The H3C S10506 switch's power consumption varies by module configuration, fan speed, and operational load, with each card and fan tray contributing to the total power draw.

Modular Power Consumption

The S10506 uses a modular design, meaning the total power consumption depends on the installed components: Line cards: Each card has a static power consumption when idle (ports down, no transceivers) and a dynamic power consumption when all ports are active and transmitting traffic. The exact wattage varies by card model and interface type. Switch fabric modules: Required for full throughput, these modules also contribute to the overall power draw.

Service modules and MPU: These sections consume additional power depending on the installed modules and operational load.

Fan Tray Power

The S10506 is equipped with fan trays that adjust speed automatically based on heat dissipation. Power consumption of the fans depends on the speed setting: Low-speed operation consumes less power. High-speed operation increases power draw to maintain optimal cooling under heavy load.

Power Supply and Redundancy

The switch supports 1 to 4 power supply modules, which can be installed in any slot. Redundant power supplies ensure high availability but also affect total power consumption. Each power supply has its own efficiency rating, which influences the overall energy usage.

Estimating Total Power

While exact numbers depend on the specific configuration, the total power consumption can be estimated by summing: Static or dynamic power of all installed line cards. Power of switch fabric, service, and MPU modules. Power consumed by fan trays at operational speed.

Overhead from power supply inefficiency. For example, a fully loaded S10506 with multiple line cards, switch fabric modules, and fans running at high speed will consume significantly more power than a minimal configuration with fewer modules and idle ports.

Practical Considerations

Data center planning: Ensure sufficient power capacity and cooling for peak load scenarios. Energy efficiency: Using fewer active ports or lower-speed fan settings can reduce power consumption. Monitoring: H3C switches often provide real-time power monitoring via management interfaces to track consumption per module.

In summary, the H3C S10506's power consumption is highly dependent on its modular configuration, operational load, and cooling requirements, and careful planning is required to estimate total energy usage accurately.
