PRODUCT IDENTIFICATION: power consumption max load idle state (PLATFORM SERIES NX-9000)

This document serves as the definitive technical datasheet for the power consumption max load idle state series of carrier-grade Ethernet switching platforms. Designed for energy-optimized datacenter and campus core deployments, this series introduces industry-leading granularity in power telemetry, enabling network architects to baseline, monitor, and dynamically scale operational expenditure (OPEX) against real-time traffic loads.

CORE INTERNAL TOPOLOGY & POWER RAIL ARCHITECTURE

The power consumption max load idle state platform integrates a dual-rail, 80 PLUS Titanium-rated power delivery network (PDN) with per-port power gating. Each forwarding ASIC (model Q-Silicon Gen5) is subdivided into 12 independent power domains. At idle state (zero traffic, link-up with LLDP), the device autonomously clocks down unused pipeline stages and places inactive SerDes lanes into a deep-sleep mode. At maximum load (line-rate non-blocking 100G traffic across all interfaces), the voltage-frequency scaling (AVFS) logic operates at peak efficiency, delivering deterministic performance with transparent thermal headroom reporting.

SWITCHING & POWER SUBSYSTEM CAPABILITIES

- IDLE STATE POWER DRAW: 78W (typical, 25°C ambient, dual PSU active/standby)

- MAXIMUM LOAD POWER DRAW: 445W (100% throughput, 64-byte frames, all ports active)

- HOT-SWAPPABLE POWER SUPPLIES: 2 x 550W AC/DC (1+1 redundancy, hot-swap)

- POWER EFFICIENCY RATIO (PER 10G): 0.18W per 10G at idle / 1.04W per 10G at max load

- TELEMETRY PROTOCOLS: In-band PMBus 1.3, SNMP Power-MIB, gRPC streaming

OPERATIONAL ADVANTAGES FOR ENERGY-AWARE NETWORKS

Compared to legacy fixed-configuration switches, the power consumption max load idle state series reduces average annual power consumption by up to 42% in typical mixed traffic patterns. The embedded intelligent power orchestration (IPO) engine automatically aligns PSU phase shedding with real-time load, eliminating redundant conversion losses. For greenfield deployments, this enables precise capacity planning without over-provisioning cooling or UPS infrastructure.
