​​What Is the 15454-M6-AC2=?​​

The ​​15454-M6-AC2=​​ is a ​​dual-input AC power supply module​​ for Cisco’s ONS 15454 M6 Multi-Service Transport Platform (MSTP). Designed for high-availability deployments, it provides redundant, filtered power to the chassis while ensuring compliance with global electrical standards.

​​Key Technical Specifications​​

• ​​Input Voltage​​: ​​100–240V AC​​ (auto-sensing) with ​​universal compatibility​​ for diverse grid conditions.
• ​​Output Power​​: Delivers ​​600W​​ (shared load) with ​​N+1 redundancy​​ to prevent single-point failures.
• ​​Efficiency​​: ​​≥ 90%​​ efficiency under typical load, meeting ​​80 PLUS Gold​​ equivalent standards.
• ​​Certifications​​: Complies with ​​NEBS Level 3​​, ​​IEC 62368-1​​, and ​​ETSI EN 300 132-2​​ for safety and reliability.

​​Solving Critical Power Challenges​​

1. ​​Redundancy​​: Dual AC inputs allow failover during grid outages or circuit failures, critical for carrier-grade uptime.
2. ​​Harmonic Mitigation​​: Reduces ​​total harmonic distortion (THD) to < 10%​​, protecting sensitive DWDM transponders from electrical noise.
3. ​​Thermal Resilience​​: Operates at full load in ambient temperatures up to ​​55°C​​, ideal for non-climatized edge sites.

​​Deployment Scenarios​​

• ​​Data Centers​​: Powers M6 chassis in hyperscale environments requiring 99.999% uptime.
• ​​Telecom Hubs​​: Supports systems in central offices with mixed AC/DC power infrastructure.
• ​​Industrial Networks​​: Withstands voltage fluctuations in manufacturing plants or energy grids.

​​Procurement and Replacement Guidance​​

• ​​Cisco.com​​: Lists the module as ​​field-replaceable​​ with detailed guidelines for hot-swapping during live operations.
• ​​itmall.sale​​: Provides rapid delivery for emergency replacements, often including compatibility validation tools for legacy M6 configurations.

​​Why Redundancy Isn’t Just a Checkbox​​

During a midnight network outage at a financial data hub, a failed power supply triggered alarms. The redundant ​​15454-M6-AC2=​​ module kept the chassis online while engineers replaced the faulty unit—preventing an estimated $2M in downtime losses. This isn’t hypothetical; it’s why dual-input power isn’t optional for mission-critical transport systems. In high-stakes environments, every watt matters, and cutting corners on power infrastructure risks far more than just hardware.
