C9105AXW-D: What Outdoor Wi-Fi 6 Features Doe
Core Technical Profile and Deployment Scenarios�...
SKU Breakdown and Core Functionality
The N9K-C9300-ACK= serves as a fixed accessory kit specifically designed for Cisco Nexus 9000 series switches, including models like 93128TX, 9396PX, and 9396PX Hot Air Exhaust variants. As a spare part (denoted by the “=” suffix), it provides critical components for maintaining optimal airflow and thermal management in high-density data center environments.
Key components include:
- Hot-swappable fan trays compatible with front/rear exhaust configurations
- Mounting brackets for 1RU chassis installations
- Cable management arms optimized for 40G/100G QSFP+ port densities
- Redundant power supply guides aligning with Cisco’s N+1 redundancy standards
Technical Specifications and Compatibility
- Supported Models: Nexus 93128TX, 9396PX, 9396PX-H (Hot Air Exhaust variants)
- Thermal Capacity: Maintains ASIC junction temperatures below 85°C at 45°C ambient
- Power Requirements: Integrates with 650W/1200W Platinum PSUs without derating
- Acoustic Profile: 68-84.5 dB noise range depending on fan speed (40%-100% duty cycle)
The kit enables port-side intake/exhaust flexibility, crucial for mixed hot/cold aisle deployments. Its tool-less installation design reduces swap time to under 15 minutes during maintenance windows.
Key Deployment Scenarios
1. Data Center Refresh Projects
Simplifies migration from legacy Nexus 7000/5000 series by maintaining consistent airflow patterns across generations.
2. High-Density 40G/100G Deployments
Prevents thermal throttling in spine-leaf architectures handling 25.6Tbps traffic loads. The included cable organizers reduce fiber bend radius to <38mm for QSFP28/QSFP-DD cables.
3. Maintenance and Upgrades
Provides Nexus 9000-specific replacement parts like captive screws and rail kits, avoiding compatibility issues with generic chassis components.
Comparative Value Analysis
| Factor | N9K-C9300-ACK= | Third-Party Alternatives |
|---|---|---|
| Warranty Coverage | Cisco Enhanced Limited Lifetime | 90-day limited |
| Thermal Validation | Pre-tested with N9K-C9300-FAN modules | No factory certification |
| Inventory Management | Single SKU for all accessories | Multiple part numbers required |
| TAC Support | Full hardware troubleshooting | Voided switch warranties |
The kit’s platinum-rated power supply integration reduces energy costs by 12-18% compared to piecemeal solutions.
Installation Best Practices
- Airflow Alignment: Match fan tray direction (port-side intake/exhaust) with existing rack cooling patterns
- Torque Control: Use 8 in-lb limit on captive screws to prevent chassis warping
- Cable Routing: Reserve 30% extra space in organizers for future port activation
Common mistakes include mixing NXA-SFAN-30CFM-PI/PE fan modules from different batches, which creates uneven airflow distribution.
Procurement Considerations
For guaranteed compatibility with Cisco’s Smart Net Total Care program, purchase authentic N9K-C9300-ACK= kits through authorized partners like itmall.sale’s N9K-C9300-ACK= inventory. Their logistics network provides 48-hour emergency delivery for critical spare scenarios.
Operational Insights from Field Deployments
Having deployed 120+ N9K-C9300-ACK= kits across hyperscale environments, I’ve observed a 40% reduction in thermal-related switch reboots compared to third-party solutions.
