What Is the Cisco CP-6823-3PC-CE-K9=? Power Capabilities, Redundancy, and Deployment Insights

​​Understanding the CP-6823-3PC-CE-K9=​​

The Cisco CP-6823-3PC-CE-K9= is a ​​3000W AC power supply module​​ designed for the Catalyst 6800 Series switches, specifically the ​​Catalyst 6807-XL and 6880-X chassis​​. It delivers high-capacity, redundant power to support PoE+ (Power over Ethernet) and non-PoE workloads in data centers, campuses, and industrial networks.

​​Core Technical Specifications​​

• ​​Input Voltage​​: 200-240V AC, 50/60Hz, with ​​active power factor correction (PFC)​​ for 94% efficiency.
• ​​Output​​: Provides ​​3000W total power​​, with up to ​​2400W allocated for PoE+ devices​​ (30W per port).
• ​​Redundancy​​: Supports ​​N+N or N+1 configurations​​ to eliminate single points of failure.
• ​​Compatibility​​: Exclusively works with Catalyst 6807-XL and 6880-X chassis running IOS-XE 16.6.1 or later.

​​Key Use Cases​​

High-Density PoE Environments

Ideal for powering ​​IP cameras, wireless APs, and VoIP systems​​ in large campuses, stadiums, or smart buildings requiring hundreds of connected devices.

Data Center Core Networks

Ensures stable power delivery for 40G/100G line cards handling traffic from virtualization clusters, storage arrays, or high-frequency trading platforms.

​​Addressing Common User Concerns​​

​​Q: Does this module support PoE++ (90W) or UPOE?​​
A: No. The CP-6823-3PC-CE-K9= is limited to ​​PoE+ (30W per port)​​. For higher power demands, consider Cisco’s UPOE-compatible modules.

​​Q: Is the power supply hot-swappable?​​
A: Yes. Failed units can be replaced without shutting down the chassis, ensuring ​​zero downtime during maintenance​​.

​​Procurement and Compatibility Checks​​

Always verify your chassis model and IOS-XE firmware version before purchasing. For genuine Cisco components and warranty support, visit the “CP-6823-3PC-CE-K9=” product page.

​​Final Observations​​

The CP-6823-3PC-CE-K9= remains a cornerstone for legacy Catalyst 6800 Series deployments, particularly where PoE+ density is non-negotiable. While newer UPOE solutions offer higher per-port wattage, this module’s proven reliability in high-stakes environments makes it a pragmatic choice for organizations with existing infrastructure. That said, future-proofing efforts should weigh the cost of maintaining older hardware against migrating to modern platforms.
