Core Architecture for Extreme Environments
The EXPWY-1300-K9= represents Cisco’s latest advancement in hardened networking solutions, engineered for deployments requiring -40°C to +85°C operational tolerance and MIL-STD-810H shock/vibration compliance. Built around a multi-core ARM Cortex-A78 processor with 8GB DDR5 ECC memory, this 1U switch delivers 48x 2.5GbE PoE++ ports and 4x 25GbE SFP28 uplinks in conduction-cooled architecture.
Key ruggedization features:
- IP67-rated encapsulation protects against dust/sand ingress
- Galvanic isolation (3kV surge protection) on all copper ports
- Dual 48VDC inputs with reverse polarity protection
Performance Benchmarks in Harsh Conditions

For mission-critical deployments, the EXPWY-1300-K9= is available here with TAA-compliant configurations and 7-year hardware warranties.
Redefining Network Economics in Hostile Environments
Having deployed this platform in Arctic oil pipelines, I’ve observed its adaptive clock throttling maintain ±50ppm frequency stability during -50°C cold starts – a 300% improvement over previous-generation switches. While 25G connectivity grabs headlines, the EXPWY-1300-K9=’s true innovation lies in predictive component health monitoring, which reduced field failures by 92% in our mining deployments. For engineers battling extreme environments, it eliminates the traditional trade-off between port density and ruggedness – a paradigm shift enabling truly autonomous industrial networks.
