​​Overview of the CP-6861-3PW-NA-K9=​​

The ​​CP-6861-3PW-NA-K9=​​ is a ​​3kW AC power supply module​​ designed for Cisco Catalyst 6800 Series switches. According to Cisco.com, this unit supports high-density deployments by delivering redundant, scalable power to chassis like the ​​Cisco Catalyst 6880-X​​. Its ​​North American (NA) voltage compliance​​ ensures compatibility with regional power grids, making it ideal for enterprise data centers requiring stable, high-capacity power distribution.

​​Key Technical Specifications​​

• ​​Power Output​​: 3000W AC, supporting dual-mode operation (combined or redundant).
• ​​Input Voltage​​: 100-240V AC, 50/60Hz.
• ​​Hot-Swappable​​: Enables replacement without disrupting switch operations.
• ​​Compatibility​​: Works exclusively with ​​Catalyst 6807-XL and 6880-X chassis​​.

​​User Concerns: Installation and Performance​​

1. ​​Can this PSU support third-party chassis?​​
   Cisco explicitly states the ​​CP-6861-3PW-NA-K9= is incompatible with non-Catalyst 6800 Series systems​​, including older 6500 platforms.

2. ​​Is redundancy automatic?​​
   Redundancy requires ​​two identical PSUs​​ installed in the chassis. A single unit operates in combined mode.

3. ​​What thermal considerations apply?​​
   At full load, the module generates significant heat. Ensure chassis airflow meets Cisco’s ​​Thermal Management Guidelines​​ to avoid overheating.

​​Sourcing the CP-6861-3PW-NA-K9=​​
