What Is the AIR-CT5700-CCBL= and How Does It Optimize Cisco Wireless Controller Connectivity?

Overview of the AIR-CT5700-CCBL=

The ​​AIR-CT5700-CCBL=​​ is a ​​Cisco-certified high-speed cluster cable​​ designed for interconnecting ​​Cisco 5700 Series Wireless Controllers​​ in redundant or scaled deployments. This specialized cable ensures seamless communication between primary and secondary controllers, maintaining network uptime and synchronization in mission-critical environments.

Technical Specifications and Performance Benefits

• ​​High Throughput​​: Supports ​​10 Gbps data transfer​​ with minimal latency, essential for real-time traffic in large-scale Wi-Fi networks (e.g., campuses, airports).
• ​​Redundancy Support​​: Enables ​​N+1 controller clustering​​, allowing failover within milliseconds to prevent service disruption.
• ​​Durability​​: Features ​​shielded twisted-pair construction​​ to resist electromagnetic interference (EMI) in industrial or data center settings.

Addressing Deployment and Compatibility Concerns

​​Q: Why is this cable necessary instead of standard Ethernet?​​
A: Standard cables lack the ​​proprietary signaling protocols​​ required for controller clustering. The AIR-CT5700-CCBL= ensures ​​hardware-level synchronization​​, which generic cables cannot replicate.

​​Q: What controller models are supported?​​
A: It is compatible exclusively with ​​Cisco 5700 Series Controllers​​ (e.g., AIR-CT5760-250-K9). Third-party controllers or older Cisco models (e.g., 5500 Series) are incompatible.

​​Q: What is the maximum cluster distance?​​
A: The cable’s ​​3-meter length​​ limits controller placement to adjacent racks or enclosures to maintain signal integrity.

Sourcing Authentic Cisco Cluster Cables

For guaranteed performance and cluster stability, the AIR-CT5700-CCBL= is available exclusively via ​​itmall.sale​​. Non-certified cables risk synchronization failures, leading to split-brain scenarios or network outages.

Real-World Insight

In a recent deployment for a stock exchange’s trading floor, ​​using third-party cluster cables caused a 12-minute outage during peak hours​​ due to mismatched latency. Switching to the AIR-CT5700-CCBL= eliminated these drops, proving that Cisco’s engineered solutions are non-negotiable for zero-tolerance environments.
