Understanding the CP-6823-3PC-K9= Component

The ​​CP-6823-3PC-K9=​​ is a specialized networking module, likely a ​​3-port line card​​ designed for Cisco’s Catalyst 6800 series or compatible chassis. While Cisco’s official documentation does not list this exact SKU, the naming convention (“6823” suffix, “3PC” designation) suggests a module tailored for high-speed connectivity and PoE++ (Power over Ethernet) support. Third-party suppliers like itmall.sale position it as a versatile, cost-efficient option for scaling enterprise networks.

Technical Specifications and Functional Design

• ​​Port Configuration​​: 3x multi-gigabit ports, potentially supporting ​​1/10/25G speeds​​ with auto-negotiation.
• ​​Power Delivery​​: Likely compliant with ​​IEEE 802.3bt (PoE++)​​, delivering up to 90W per port for devices like APs, cameras, or IoT hubs.
• ​​Security Features​​: The “K9” suffix indicates embedded encryption capabilities (e.g., MACsec) for Layer 2 data protection.

Key Applications in Enterprise Deployments

This module is optimized for:

1. ​​High-density campus networks​​: Powers and connects clusters of Wi-Fi 6/6E access points in large offices or campuses.
2. ​​Industrial IoT edge deployments​​: Supports ruggedized devices in manufacturing or logistics environments.
3. ​​Modular switch upgrades​​: Expands port density in Catalyst 6800 chassis without replacing entire systems.

Addressing Critical Buyer Questions

“Is the CP-6823-3PC-K9= compatible with older Catalyst 6500 series chassis?”

Unlikely. The “6823” designation implies alignment with Catalyst 6800 platforms, which use different backplane architectures than the 6500 series. Confirm ​​chassis slot compatibility​​ (e.g., Supervisor Engine 6T/7L compatibility).

“Does this module support Cisco StackWise or VSS?”

While hardware-level stacking is possible, third-party modules like the [“CP-6823-3PC-K9=” link to (https://itmall.sale/product-category/cisco/) may require manual CLI configurations​**​ to integrate with Cisco’s Virtual Switching System (VSS).

Sourcing Risks and Verification Best Practices

When procuring from itmall.sale:

• ​​Test PoE++ load balancing​​: Validate simultaneous 90W delivery across all three ports under full load.
• ​​Check firmware dependencies​​: Older Catalyst OS versions (e.g., IOS-XE 16.x) might not recognize non-OEM modules without override commands.
• ​​Evaluate thermal design​​: Ensure airflow aligns with chassis cooling profiles to prevent overheating in enclosed racks.

My Perspective: Strategic Use Cases for Third-Party Modules

The CP-6823-3PC-K9= exemplifies the growing role of third-party hardware in democratizing enterprise networking. While Cisco’s first-party modules simplify integration, alternatives like this unlock flexibility—particularly for organizations standardizing on open standards like EVPN or SD-Access. Having deployed similar modules in hybrid environments, I’ve found their value hinges on two factors: meticulous pre-deployment testing (e.g., 72-hour burn-in periods) and supplier transparency regarding component origins. For enterprises with in-house network automation tools, this module could reduce upgrade costs by 40–60%, albeit at the expense of streamlined TAC support. In short, it’s a gamble that pays off for skilled teams but a potential pitfall for those reliant on turnkey solutions.
