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
- Redundancy: Dual AC inputs allow failover during grid outages or circuit failures, critical for carrier-grade uptime.
- Harmonic Mitigation: Reduces total harmonic distortion (THD) to < 10%, protecting sensitive DWDM transponders from electrical noise.
- 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

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.
