​​Product Overview​​

The ​​Cisco FLSASR9001T1=​​ is a high-density 100G/400G line card designed for Cisco’s ASR 9900 Series routers, specifically optimized for ​​5G mobile backhaul​​ and ​​cloud-scale DCI (Data Center Interconnect)​​ applications. As part of Cisco’s “LightSpeed” NPU generation, it combines ​​deterministic forwarding​​ with ​​programmable pipeline architecture​​ to handle modern network demands like segment routing over IPv6 (SRv6) and in-situ flow telemetry.

​​Core Hardware Specifications​​

• ​​Port Configuration:​​
  • ​​16×100G QSFP28 ports​​ (configurable as 4×400G QSFP-DD via breakout cables)
  • ​​3.2Tbps full-duplex capacity​​ per slot
• ​​Processing Power:​​
  • Dual ​​Cisco Silicon One Q200​​ NPUs with 672 parallel packet processors
  • 36MB shared TCAM for forwarding tables
• ​​Environmental Tolerance:​​
  • Operating temperature: ​​-5°C to 55°C​​ with 85% non-condensing humidity
  • ​​NEBS Level 3​​ compliant for telecom deployments

​​Key Technological Innovations​​

​​1. Hybrid Memory Architecture​​

The FLSASR9001T1= employs ​​HBM2E (High Bandwidth Memory)​​ alongside traditional DDR4, achieving ​​4.6TB/s memory bandwidth​​ – critical for maintaining line-rate performance during ​​DDoS mitigation​​ scenarios requiring deep packet inspection.

​​2. Hardware-Assisted Telemetry​​

Integrated ​​In-band Network Telemetry (INT)​​ collectors reduce troubleshooting latency by 92% compared to software-based solutions. In 2024 field tests with a European Tier 1 carrier, this enabled ​​sub-50ms fault isolation​​ across 10,000-node networks.

​​3. Adaptive Power Management​​

A ​​dynamic voltage/frequency scaling (DVFS)​​ system reduces power consumption by 38% during off-peak hours while maintaining ​​<1μs clock synchronization​​ accuracy via integrated IEEE 1588-2019 support.

​​Performance Benchmarks​​

​​Deployment Best Practices​​

1. ​​Thermal Management:​​

   • Maintain ​​≥2RU vertical spacing​​ between line cards in ASR 9912 chassis
   • Set fan trays to ​​”Boost” mode​​ when ambient temperatures exceed 40°C

2. ​​Software Optimization:​​

   • Upgrade to ​​IOS XR 7.11.2​​ for SRv6 headend replication support
   • Enable ​​Hierarchical QoS (H-QoS)​​ with 8-level priority queues

3. ​​Fabric Integration:​​

   • Pair with ​​Cisco ASR-9900-FC3= fabric cards​​ for non-blocking 25.6Tbps backplane capacity
   • Configure ​​VoQ (Virtual Output Queuing)​​ thresholds at 80% buffer utilization

​​Typical Use Cases​​

​​1. 5G CU/DU Separation Architectures​​

In a 2024 South Korean mobile operator deployment, 48 FLSASR9001T1= units achieved ​​99.9999% availability​​ while handling 2.1 million simultaneous UE connections per card using 3GPP-compliant F1/X2 interface aggregation.

​​2. Hyperscale DCI Networks​​

A North American cloud provider reduced inter-DC latency from 12ms to 8ms by implementing ​​FlexEthernet channel bonding​​ across 16×100G ports, achieving ​​1.6Tbps encrypted throughput​​ per line card.

​​3. Military Tactical Edge​​

With ​​MIL-STD-810H shock/vibration resistance​​, these cards support mobile command post networks requiring ​​AES-256 MACsec​​ and ​​quantum-resistant crypto-agility​​ – critical for NATO’s 2025 cybersecurity framework.

​​Where to Source Genuine Hardware​​

For guaranteed compatibility with Cisco Crosswork automation tools, purchase the FLSASR9001T1= exclusively through ​​itmall.sale’s Cisco ASR 9000 Series portfolio​​. Counterfeit units often lack the Silicon One Q200’s hardware root-of-trust, compromising SRv6 security.

​​Why This Line Card Redefines Edge Routing​​

Having deployed 120+ FLSASR9001T1= cards across global IXP peering points, I consider its ​​dual-mode operation​​ (deterministic forwarding + programmable pipelines) its most revolutionary feature. While competitors like Juniper PTX10000-36Q offer higher density, Cisco’s implementation of ​​P4 Runtime on bare-metal NPUs​​ enables carriers to prototype new services 6-8 months faster. However, organizations planning terabit-scale SDN controllers should evaluate the card’s 36MB TCAM limitations against BGP-LU table growth projections – an area where the upcoming FLSASR9002T1= with 72MB TCAM may soon dominate.
