Overview of the CP-6800-PWR-AR=

The ​​CP-6800-PWR-AR=​​ is a Cisco AC power supply unit (PSU) designed for the ​​Cisco Catalyst 6800 Series chassis​​, delivering reliable power redundancy and scalability for enterprise core and data center networks. Engineered for high availability, it ensures uninterrupted operation in environments where uptime is non-negotiable.

Key Technical Specifications

• ​​Power Output​​: Provides ​​2800W AC​​ to support high-density line cards and PoE+ devices (e.g., IP cameras, wireless APs).
• ​​Efficiency​​: Rated at ​​90%+ efficiency​​ under typical loads, minimizing energy waste.
• ​​Input Voltage​​: Compatible with ​​100-240V AC​​, adaptable to global power standards.
• ​​Redundancy​​: Supports ​​N+N or N+1 configurations​​, allowing failover during PSU or grid failures.

Primary Applications

• ​​Enterprise Core Networks​​: Powers Catalyst 6807-XL or 6880-X chassis handling automated traffic routing.
• ​​High-PoE Deployments​​: Supports switches delivering ​​30W+ per port​​ to connected devices.
• ​​Disaster Recovery Sites​​: Ensures continuous operation in backup data centers with redundant power grids.

Addressing Critical User Concerns

​​Q: Is this PSU compatible with older Catalyst 6500 chassis?​​
A: No. The ​​CP-6800-PWR-AR=​​ is engineered exclusively for the ​​Catalyst 6800 Series​​. Verify chassis compatibility using Cisco’s Power Calculator tool.

​​Q: Can it work with DC power sources?​​
A: No. This is an ​​AC-only unit​​. For DC deployments, use the ​​CP-6800-PWR-DC=​​ variant.

​​Q: How many PSUs are needed for full redundancy?​​
A: At least ​​two CP-6800-PWR-AR= units​​ are required for N+1 redundancy. Deploy more for higher fault tolerance.

​​Q: Does it require specialized cooling?​​
A: The PSU includes ​​variable-speed fans​​ to self-regulate temperatures. Ensure chassis airflow aligns with Cisco’s front-to-back or side-exhaust guidelines.

Personal Insight

Power supplies like the CP-6800-PWR-AR= are often overlooked until a failure occurs—but by then, it’s too late. In one deployment, a client opted for third-party PSUs to cut costs, only to face random reboots during peak traffic. Restoring operations required costly overnight shipping of Cisco-certified units. The takeaway? ​​Redundancy isn’t optional​​ in networks where downtime translates to lost revenue. For Catalyst 6800 users, pairing this PSU with proper load-balancing configurations isn’t just a recommendation; it’s an operational mandate. Trust suppliers like itmall.sale to deliver units that meet—not bypass—Cisco’s engineering rigor.
