Field Maintenance Insights
From 17 enterprise deployments monitored via Cisco TAC:
- Mean Time Between Failures: 146,000 hours (16.7 years) with dual supervisors
- Common Configuration Errors:
- Under-provisioning BFD timers (<200ms causes false positives)
- Mismatched airflow direction in mixed chassis environments
Operational Reality Assessment
The N9800-HV-TRAY= redefines chassis-based switching economics – its modular power shelf design allows incremental 6.4kW expansions without service interruption. While the $284,000 base chassis cost appears steep, the 400G readiness eliminates fork-lift upgrades for 10+ years. For enterprises requiring >100Tbps non-blocking fabrics, this platform outperforms alternatives in OpEx/performance ratio by 4:1 (Cisco Validated Design 16.2).
