CAB-C13-CBN-C=: What Cisco Hardware Needs It, How Does It Ensure Compliance, and Why Do Generic Cables Fall Short?

​​Defining the CAB-C13-CBN-C= Power Cable​​

The ​​CAB-C13-CBN-C=​​ is a Cisco-certified AC power cable combining a C13 connector (IEC 60320) with a country-specific CBN plug. Designed for devices requiring precise voltage delivery and regional safety compliance, this cable bridges Cisco hardware with localized power infrastructure while adhering to stringent certification protocols.

​​Core Technical Specifications​​

• ​​Voltage Range​​: 100–240V AC, 50/60Hz (global dual-voltage support).
• ​​Connectors​​: C13 (equipment end) to CBN plug (regionally optimized, e.g., Brazil’s NBR 14136 Type N).
• ​​Certifications​​: Regional safety marks (e.g., INMETRO for Brazil, KC for Korea) + Cisco’s internal validation.
• ​​Compatibility​​: Cisco UCS C-Series servers, Catalyst 9300/9400 switches, and ASR 1000 routers.

​​Primary Use Cases​​

• ​​Multinational Deployments​​: Powering UCS C220 servers in regions with strict plug compliance (e.g., Brazil, South Korea).
• ​​Hybrid Data Centers​​: Ensuring Catalyst 9400 switches meet local electrical codes without adapter reliance.
• ​​Edge Sites​​: Supporting ASR 1000 routers in areas requiring fused plugs for overcurrent protection.

​​User Concerns Addressed​​

​​Can the CAB-C13-CBN-C= replace generic C13-to-regional cables?​​

No. While generic cables may fit physically, the ​​CAB-C13-CBN-C=​​ is firmware-validated for Cisco’s power management. Third-party cords risk tripping PSU fault protections or failing safety audits.

​​Is this cable backward-compatible with older UCS M4 servers?​​

Yes, provided the server’s PSU uses a C14 inlet (paired with C13). Verify voltage compatibility (100–240V) on the PSU label.

​​How does it differ from CAB-C15-C20= high-temp models?​​

The ​​CAB-C15-C20=​​ uses a C19/C20 connector rated for 120°C environments (e.g., data center hot aisles), while the CBN-C variant prioritizes regional plug compliance and standard thermal ranges.

​​Does the CBN plug support daisy-chaining PDUs?​​

No. The CBN plug is designed for direct wall/outlet connections. For PDU use, opt for C13-to-C14 cables like ​​CAB-C13-C14=​​.

​​Procuring Reliable CAB-C13-CBN-C= Cables​​

To avoid counterfeit units lacking regional certifications, source directly from ​​itmall.sale’s Cisco inventory​​, which guarantees authentic, compliance-ready cables with full warranty coverage.

​​Engineer’s Viewpoint​​

In regions where plug compliance isn’t just a technicality but a legal mandate, the ​​CAB-C13-CBN-C=​​ transcends being a mere accessory—it’s a liability shield. While generic cables might save pennies upfront, the fallout from failed inspections or thermal mismatches in high-load scenarios dwarfs those savings. For global deployments, cutting corners on localized power infrastructure is a gamble no prudent engineer should take.
