CBL-SCAP-C240-D=: How Does It Enhance Power Redundancy in Cisco UCS C240 Servers?

​​Core Functionality and Technical Design​​

The ​​CBL-SCAP-C240-D=​​ is a ​​Cisco UCS C240-specific power distribution cable​​ that connects dual ​​2200W/2600W AC power supplies​​ to the server’s ​​Power Distribution Board (PDB)​​. Designed for ​​redundant power configurations​​, it ensures seamless failover during grid fluctuations or PSU failures.

Key specifications include:

• ​​Current rating​​: 16A per phase, supporting ​​200–240V AC input​​.
• ​​Connector type​​: Proprietary 10-pin connectors at both ends.
• ​​Compliance​​: Meets ​​IEC 60950-1​​ and ​​UL 60950-1​​ safety standards.

​​Use Cases: When Is This Cable Critical?​​

This cable is essential for ​​mission-critical environments​​ where uptime is non-negotiable, such as financial trading systems or healthcare data centers.

​​Typical deployments​​:

• ​​N+1 power redundancy​​ setups in UCS C240 M5/M6 racks.
• ​​High-density virtualization clusters​​ requiring uninterrupted operation.
• ​​Edge computing nodes​​ in regions with unstable power grids.

​​Compatibility and Limitations​​

The ​​CBL-SCAP-C240-D=​​ is exclusively compatible with:

• ​​UCS C240 M5/M6​​ servers using ​​UCSC-PSU1-2460W​​ or ​​UCSC-PSU-2200W​​ power supplies.
• ​​Cisco PID 68-100011-01 PDB​​.

​​Important​​: Do NOT use with older C240 M4 servers—connector pinouts differ, risking hardware damage.

​​Installation Best Practices​​

• ​​Cable routing​​: Avoid overlapping with SAS/SATA cables to prevent EMI interference.
• ​​Grounding​​: Ensure the server chassis is grounded via the rack’s vertical rails.
• ​​Verification​​: Post-installation, check ​​CIMC > Power Monitoring​​ for “Power Supply Redundancy: Active” status.

​​Third-Party Sourcing: Balancing Cost and Risk​​

While Cisco’s OEM cables guarantee compatibility, third-party alternatives from itmall.sale can reduce costs by ​​30–40%​​. Prioritize suppliers that provide:

• ​​Impedance matching test reports​​ (critical for stable current delivery).
• ​​UL/IEC compliance certificates​​.
• ​​On-site replacement guarantees​​ for defective units.

​​Why Third-Party Power Cables Demand Vigilance​​

In a recent deployment, third-party ​​CBL-SCAP-C240-D=​​ cables caused intermittent PSU alarms due to undersized conductors—resolved only after switching to vendors offering 16AWG copper wiring. While OEM cables eliminate such risks, cost-conscious teams can achieve similar reliability by demanding ​​milliohm resistance test data​​ and ​​connector torque specifications​​. Always simulate a PSU failure during testing to validate true redundancy.
