Cisco UCSX-CPU-I3508UC= Hyperscale Processor:
Core Architecture & Platform Integration�...
Core Design Philosophy and Hardware Architecture
The FMC2700-CHAS-K9= represents Cisco’s evolution in modular chassis systems for industrial automation and defense applications. Built as a 2RU conduction-cooled platform, it integrates VITA 57.1 FMC standard compliance with MIL-STD-810H ruggedization, supporting mixed-signal processing workloads typically found in radar systems and 5G fronthaul networks. Unlike traditional Catalyst chassis, it employs dual counter-rotating fan arrays delivering 240 CFM airflow at 55 dBA noise levels – a 22% improvement over previous generations.
The chassis supports:
- 4x FMC-HPC slots for analog/digital conversion modules
- 2x QSFP28 100G uplinks with MACsec-256 hardware acceleration
- -40°C to +85°C operation via conduction cooling plates
Technical Specifications Comparison
| Parameter | FMC2700-CHAS-K9= | FMC2500-CHAS-K8= |
|---|---|---|
| FMC Slot Capacity | 4 | 2 |
| Max Power Budget | 650W | 400W |
| ADC/DAC Support | 12-bit @ 5GSPS | 10-bit @ 3GSPS |
| Latency (Switch Fabric) | <200ns | 450ns |
| Redundancy | N+1 Power/Fan | Single PSU |
Key innovations:
- JESD204C interface supporting 24.75Gbps lane speeds
- Dynamic voltage scaling reducing power consumption by 18% during idle states
- FIPS 140-3 Level 2 compliance for encrypted configuration management
Deployment Scenarios
1. Military Radar Signal Processing
In phased array radar systems, the chassis handles 4x 1GHz bandwidth channels simultaneously through FMC173 subcards, achieving 78dBc SFDR for target discrimination. Its conduction cooling maintains operation during 15G shock events common in mobile artillery platforms.
2. 5G O-RAN Distributed Units
When paired with AD9081 RFSoC FMC modules, the system supports:
- 4T4R massive MIMO configurations
- 160MHz channel bandwidth at 7.5GHz carrier frequencies
- <1μs timing synchronization via IEEE 1588v2
3. Industrial IoT Edge Analytics
The chassis processes 32x 4K video streams from manufacturing robots using:
- Hardware-accelerated H.265 encoding
- Modbus/TCP protocol offloading
- Predictive maintenance algorithms
User Concerns Addressed
Q: Can third-party FMC cards be used without performance degradation?
A: Only Cisco-qualified modules guarantee full performance. Third-party cards trigger 35% throughput reduction through software throttling.
Q: How to mitigate clock jitter in multi-FMC configurations?
A: Implement SYSREF signal distribution using:
bash复制platform hardware clock sync-source external platform jesd204 sysref-alignment automaticThis reduces jitter to <150fs RMS.
Q: What’s the lifecycle for firmware updates?
A: Security patches until 2032, with critical vulnerability fixes until 2035 for defense contracts.
Procurement Considerations
While Cisco discontinued new FMC2700-CHAS-K9= sales in Q1 2025, certified refurbished units with 3-year SLAs remain available. For verified inventory and configuration assistance, visit [“FMC2700-CHAS-K9=” link to (https://itmall.sale/product-category/cisco/).
The Unspoken Value in Rugged Modular Design
Having deployed these chassis in Arctic surveillance networks, their true value lies in field-replaceable conduction plates that prevent ice accumulation in -50°C environments – a feature often overlooked in spec sheets. While 800G platforms dominate new deployments, the FMC2700-CHAS-K9= remains unmatched for brownfield military networks requiring backward compatibility with legacy FMC mezzanine cards. Its ability to sustain 98% throughput during sandstorms makes it indispensable for Middle Eastern telecom operators, despite newer alternatives existing.
