CW9166I-F: What Is Cisco’s Latest Wi-Fi 6 A
Overview of the CW9166I-F The Cisco C...
Product Overview and Functional Role
The CBR-PEM-AC-6M= is a Cisco AC power entry module designed to provide redundant, high-efficiency power distribution for enterprise-grade Cisco chassis systems. With a 6-meter input cable and dual AC power inputs, it ensures uninterrupted power delivery to critical networking hardware like the Cisco ASR 9000 or Catalyst 9400 Series.
Key Technical Specifications
- Input Voltage: 100–240V AC (50/60Hz).
- Output: Distributes power to chassis backplane with up to 3000W capacity.
- Cable Length: 6 meters (suits installations with distant power sources).
- Connector Type: IEC 60320 C19/C20 inlets.
- Compatibility: Cisco ASR 9006/9010, Catalyst 9407/9410 chassis.
Primary Use Cases
- Data Center Redundancy: Supports N+1/N+N power redundancy configurations.
- Remote IDF Closets: Extends power reach in distributed network closets.
- High-Availability Deployments: Minimizes downtime during grid fluctuations or PSU failures.
Critical Compatibility Requirements
- Chassis Support: Requires Cisco ASR 9006/9010 or Catalyst 9407/9410 chassis with PEM slots.
- Power Supply Pairing: Designed to work with Cisco’s 3kW AC power supplies (e.g., PWR3K-AC).
- Rack PDUs: Ensure rack PDUs support IEC 60320 C19 outlets for seamless integration.
User Concerns: Addressing Key Questions
Q: Can this PEM module support DC power inputs?
A: No—the CBR-PEM-AC-6M= is AC-only. For DC deployments, use Cisco’s CBR-PEM-DC-6M= variant.
Q: Is the 6-meter cable length sufficient for raised-floor data centers?
A: Yes, but verify cable routing paths to avoid tight bends exceeding the 50mm bend radius.
Q: Does it require dedicated circuit breakers?
A: Yes—each AC input should connect to a 20A circuit breaker for safety.

Performance Comparison: Cisco vs. Generic PEM Modules
| Criteria | CBR-PEM-AC-6M= | Generic PEM Module |
|---|---|---|
| Surge Protection | 6kV/3kA | 2kV/1kA (typical) |
| Operating Temperature | -40°C to 75°C | 0°C to 60°C |
| MTBF (Mean Time Between Failures) | 500,000 hours | 200,000 hours (estimated) |
Engineer’s Perspective: The Hidden Risks of Non-Cisco PEMs
In power distribution, subtle design flaws—like inadequate surge protection or undersized conductors—can lead to catastrophic failures during grid anomalies. While generic PEMs might meet basic specs, their lack of end-to-end Cisco validation leaves networks vulnerable. For mission-critical environments, the CBR-PEM-AC-6M= isn’t just a component; it’s the backbone of operational resilience.
