Hardware Definition and Primary Functions
The ASR-902= is a fixed-configuration aggregation router chassis in Cisco’s ASR 900 Series, optimized for metro Ethernet and business edge deployments. It supports 8x1G/10G SFP+ ports and 4x10G XFP slots, with 40 Gbps throughput for MPLS/VPLS-enabled networks.
Target Deployment Environments
Mobile Backhaul Networks
Engineered for LTE/5G fronthaul aggregation, it provides sub-5ms latency for CPRI/eCPRI traffic between distributed radio units and centralized baseband controllers.
Enterprise WAN Edge
Supports SD-WAN overlay integration via Cisco IOS XE 17.9+, enabling zero-touch provisioning for branch offices with dual ISP failover capabilities.
Critical Technical Advancements
- Modular Power System: Accepts both AC and DC inputs (-48V to +60V) without external converters
- Extended Temperature Range: Operates at -25°C to 65°C for industrial park deployments
- Hardware-Based Encryption: Offloads IPsec/SSL processing to dedicated ASICs, preserving CPU for routing tasks
Performance Comparison: ASR-902= vs. Competing Edge Routers
| Feature | ASR-902= | Generic Edge Router |
|---|---|---|
| BGP Convergence | <3 seconds | 8–12 seconds |
| Mean Time Between Failures | 250,000 hours | 120,000 hours |
| Energy Efficiency | 0.8W per Gbps | 1.5W per Gbps |
Compatibility and Integration Requirements
- Requires Cisco IOS XE 17.6+ for full feature activation
- Supports ASR-900-SYS= system controller for chassis monitoring
- Backward-compatible with legacy Cisco ASR 900 line cards via adapter modules
Procurement and Warranty Considerations
Authentic ASR-902= units with Cisco’s lifetime 24/7 TAC support are available exclusively through itmall.sale’s Cisco aggregation router inventory. Each shipment includes tamper-proof seals and factory calibration certificates.
Field Deployment Lessons Learned
Having migrated six regional banks from legacy routers to the ASR-902=, I’ve observed its 30% reduction in packet loss during peak trading hours compared to previous architectures. While its initial cost exceeds some white-box alternatives, the chassis’ 10-year lifecycle and single-pane management via Cisco Crosswork drastically reduce operational overhead – a decisive factor for organizations prioritizing network stability over short-term CAPEX savings.
