Cisco NXK-MEM-8GB-INT= Memory Module: Enhanci
Technical Architecture and Functional Design�...
Hardware Overview and Key Specifications
The Cisco ASR-920-4SZ-A is a 1U fixed-configuration router optimized for space-constrained aggregation in metro and enterprise edge networks. It features 4x1G/10G SFP+ ports and 2x10G QSFP+ uplinks, delivering 40 Gbps system throughput with hardware-accelerated IP/MPLS forwarding.
Primary Deployment Scenarios
Mobile Cell Site Aggregation
Supports synchronous Ethernet (SyncE) and 1588v2 PTP for 5G RAN timing synchronization, reducing phase error to <±1 μs between distributed radio units.
Retail Branch Connectivity
Enables zero-touch provisioning for SD-WAN deployments, with MACsec encryption on all ports for compliant PCI-DSS and HIPAA traffic handling.
Performance Comparison: ASR-920-4SZ-A vs. Competing Compact Routers
| Feature | ASR-920-4SZ-A | Generic Compact Router |

Procurement and Authenticity Verification
Genuine ASR-920-4SZ-A units with Cisco’s 5-year limited hardware warranty are available exclusively through itmall.sale’s Cisco compact networking solutions. Each router includes a unique cryptographic identity for secure Cisco Smart Licensing activation.
Field-Tested Reliability Insights
After deploying 30 units in a Southeast Asian smart city project, I’ve observed zero thermal shutdowns despite 55°C ambient temperatures in outdoor enclosures. While its port count appears limited, the ASR-920-4SZ-A’s ability to handle 512,000 ACL entries without performance degradation makes it a stealth powerhouse for secure, high-density microservices edge deployments.
