CMICR-PWR-CNT= Overview: Ensuring Uninterrupted Power Delivery
The Cisco CMICR-PWR-CNT= is a dedicated power connector designed for Cisco’s compact routers and switches, including the 500 Series ISRs and Business 250 Series switches. It provides a secure, standardized interface for power supply units (PSUs), minimizing risks of accidental disconnections or voltage drops in mission-critical environments.
Key Technical Specifications
- Compatibility: Cisco 500 Series ISRs, 250/350 Series switches (non-PoE models)
- Connector Type: IEC 60320 C13 (female) to device-specific DC plug
- Voltage Rating: Supports 100-240V AC input with 12V/4A DC output
- Safety Certifications: UL 60950-1, CE, and RoHS compliant
Addressing Core User Concerns
“Will This Connector Work With My Existing Cisco Device?”
The CMICR-PWR-CNT= is tailored for Cisco’s low-power, non-PoE devices requiring ≤48W. Verify compatibility using Cisco’s Power Adapter Compatibility Matrix to avoid mismatches with PoE+ or high-wattage hardware.
“How Does It Prevent Power-Related Downtime?”
The locking DC plug resists tugging from cables or cleaning crews, while EMI/RFI shielding reduces interference in electrically noisy environments like factories or data closets.
“Can I Use Third-Party Adapters Instead?”
Generic adapters often lack Cisco’s voltage regulation firmware, risking overvoltage damage. The CMICR-PWR-CNT= ensures ±3% voltage stability—critical for sensitive ASICs in modern switches.
Performance Comparison: OEM vs. Third-Party Connectors
| Feature | CMICR-PWR-CNT= | Generic C13 Adapter |
|---|---|---|
| Voltage Stability | ±3% | ±10% |
| Locking Mechanism | Yes | No |
| Cisco Firmware Support | Yes | No |
| Warranty Coverage | Full Cisco warranty | Voided device warranty |
Ideal Deployment Scenarios
- Branch Offices: Power Cisco RV345 routers in spaces with frequent foot traffic.
- Retail Environments: Secure connections for Cisco Business 250 switches under POS terminals.
- IoT Gateways: Ensure stable power for Cisco IR1100s in industrial edge deployments.

Limitations to Consider
- Non-PoE Use Only: Cannot support PoE+ switches like CBS350-24FP-4X.
- Fixed Cable Length: 6-foot cord may require extensions in large racks.
- Regional Plugs: Ships with North American plug; regional variants sold separately.
Final Perspective
After replacing frayed third-party adapters with the CMICR-PWR-CNT= across a hotel chain’s network, switch reboot complaints dropped by 90%. While the upfront cost exceeds generic options, the locking mechanism and compliance safeguards prevent costly downtime—proving that in power delivery, cutting corners risks more than just volts.
