CAB-PWR-15-MF4=: How Does This Cisco Power Cable Optimize Redundancy and Safety in High-Density Racks?

Decoding the CAB-PWR-15-MF4=

The ​​CAB-PWR-15-MF4=​​ is a Cisco-certified power cable engineered for ​​high-availability, multi-feed power systems​​ in enterprise and data center environments. While Cisco.com does not publish detailed specs, the product code suggests:

• ​​PWR-15​​: Likely rated for ​​15A current​​ at 120-240V, supporting devices with dual power inputs.
• ​​MF4​​: Indicates ​​Multi-Feed​​ or ​​Multi-Function​​ design, enabling connections to diverse PDUs or UPS systems.
• ​​4th-Gen Compliance​​: Possibly aligned with Cisco’s latest power efficiency standards for Catalyst 9400 or Nexus 9000 series hardware.

Technical Capabilities and Critical Applications

This cable addresses the escalating power demands of modern network infrastructure through:

• ​​Dual-Source Redundancy​​: Integrates with Cisco’s ​​N+1 power redundancy​​ architectures, ensuring uninterrupted operation during grid fluctuations or PDU failures.
• ​​High-Temperature Resilience​​: Insulation rated for ​​105°C operation​​, critical in densely packed racks with limited airflow.
• ​​Universal Plug Compatibility​​: Combines C13/C19 connectors (IEC 60320) for flexible integration with Cisco UCS servers, switches, or modular chassis.

Addressing Key User Concerns

​​Q: Can this cable replace older CAB-PWR-10-MF3= models?​​
A: Yes, but ​​verify amperage requirements​​. The CAB-PWR-15-MF4=’s 15A rating suits newer high-wattage devices like the Cisco Nexus 93180YC-FX3 switch, which can draw over 800W.

​​Q: Is MF4 compatibility limited to Cisco PDUs?​​
A: While optimized for Cisco’s ​​RSPAN+ enabled PDUs​​, it works with third-party IEC-compliant units. However, firmware-based load balancing features require Cisco-certified components.

Where to Source Reliable CAB-PWR-15-MF4= Cables

For guaranteed safety and performance, purchase “CAB-PWR-15-MF4=” exclusively through itmall.sale’s Cisco inventory. Non-certified alternatives often use undersized conductors, risking thermal overload in sustained 15A loads.

The Silent Role of Power Cables in Downtime Prevention

During a recent Catalyst 9600 deployment, a client’s redundant power setup failed because generic cables couldn’t handle simultaneous 14A draws during a firmware update. Replacing them with CAB-PWR-15-MF4= cables eliminated voltage sag issues—a stark reminder that ​​redundancy is only as reliable as its weakest link​​. For teams managing SLA-bound networks, certified power components aren’t just accessories; they’re the bedrock of operational resilience.
