Cisco StackWise-480, 50cm - InfiniBand cables

Cisco StackWise‑480 50 cm InfiniBand Stacking Cable

The Cisco StackWise‑480 50 cm InfiniBand Stacking Cable is a high‑performance interconnect designed to enable seamless stacking of Cisco Catalyst switches that support the StackWise‑480 technology. This cable provides a dedicated, low‑latency link between stack members, allowing them to operate as a single logical device while preserving individual management and redundancy.

Key Features

• InfiniBand Interface: Utilizes the InfiniBand protocol for ultra‑fast data transfer, delivering up to 100 Gbps of aggregate bandwidth across stacked units.
• Compact Length: At exactly 50 cm (0.5 m), the cable offers a balance between flexibility and signal integrity, ideal for dense rack environments.
• Robust Construction: Shielded twisted‑pair design protects against electromagnetic interference (EMI) and crosstalk, ensuring reliable operation in high‑density data centers.
• Plug‑and‑Play Compatibility: Fully compatible with Cisco Catalyst 3850, 3850‑24, 3850‑48, and other StackWise‑480 capable switches without the need for additional configuration.
• High Reliability: Designed to meet Cisco’s stringent quality standards, providing consistent performance over extended periods of operation.

Technical Specifications

Installation Guidelines

1. Select the correct port: On each switch, locate the dedicated StackWise‑480 InfiniBand ports. These are typically labeled “Stack” or “InfiniBand.”
2. Insert the cable: Connect one end of the 50 cm cable to the first switch’s stack port and the other end to the second switch’s corresponding port.
3. Secure connections: Ensure that each connector is fully seated; a snug fit guarantees optimal signal integrity.
4. Power on the switches: Once all cables are connected, power up the stack members. The switches will automatically detect the link and integrate into the stack.
5. Verify stack status: Use the switch’s command‑line interface (CLI) or graphical management tool to confirm that both units appear in the same stack group and share a unified configuration.

Operational Benefits

• Unified Management: Treat multiple physical switches as a single logical device, simplifying configuration, monitoring, and firmware upgrades.
• High Availability: If one switch fails, the remaining stack members continue to operate without interruption, maintaining full network throughput.
• Scalable Architecture: Add or remove switches from the stack with minimal downtime, allowing organizations to grow their switching capacity as needed.
• Reduced Cabling Complexity: A single InfiniBand cable replaces multiple Ethernet uplinks, freeing rack space and reducing clutter.

Maintenance & Troubleshooting Tips

• Visual Inspection: Periodically check connectors for dust or damage. Clean with a dry, lint‑free cloth if necessary.
• Signal Integrity Checks: Use the switch’s diagnostic commands (e.g., “show stack‑link”) to monitor link status and error rates.
• Replace Faulty Cables: If a stack member reports a link failure, swap the cable with a known good unit to isolate the issue.
• Firmware Updates: Ensure that all stack members run compatible firmware versions; mismatched software can cause stack instability.
