What Is the ASR-914-PWR-FAN=?
The ASR-914-PWR-FAN= is a combined power supply and fan tray module designed for Cisco’s ASR 914 Aggregation Services Router. It provides N+1 reduncy for power delivery and active cooling, ensuring continuous operation in service provider edge and enterprise WAN deployments. Unlike standalone power or fan units, this integrated solution aligns with Cisco’s thermal design to prevent overheating in high-ambient environments.
Core Technical Capabilities
- Power Output: 3000W AC or 2400W DC, supporting ASR 914’s full slot capacity (up to 800G per slot).
- Fan Speeds: Variable-speed fans auto-adjust based on temperature sensors, reducing noise during low-load periods.
- Redundancy: Hot-swappable design allows replacement without chassis downtime.
- Compatibility: Works only with ASR 914 chassis (not backward-compatible with ASR 900 or 9000 Series).
Why the ASR-914-PWR-FAN= Is Non-Negotiable
| Factor | ASR-914-PWR-FAN= | Generic PSU/Fan Combos |
|---|---|---|
| Thermal Design | Precision airflow for ASR 914’s layout | Generic airflow risks hot spots |
| Power Efficiency | 94% efficiency (Platinum-rated AC) | 80–88% efficiency (no certification) |
| Cisco Smart Net | Fully covered under support contracts | Voids ASR 914 warranty |
| Alarm Integration | Sends SNMP traps for pre-failure alerts | No native chassis integration |
Critical Deployment Scenarios
1. High-Density Edge Deployments
In 5G mobile backhaul nodes, the module’s dual power feeds and adaptive cooling prevent throttling during peak traffic surges.
2. Industrial Environments
Rated for -40°C to 70°C operation, it supports transportation or utility networks with extreme temperature fluctuations.
3. Data Center Interconnects
Ensures uninterrupted service during brownouts or cooling failures, critical for financial and cloud peering traffic.
Addressing Common Maintenance Concerns
-
How Often to Replace?
Cisco recommends preventive replacement every 5 years or 50,000 hours, whichever comes first. -
Can Third-Party Fans Be Used?
No. Mixing non-Cisco fans disrupts airflow balance, risking thermal shutdowns. -
Troubleshooting Fan Errors
-
Verify chassis firmware is updated to 17.8.1+ (fixes false RPM alarms).
-
Clean air filters monthly in dusty environments.

Field-Tested Insight
After witnessing a major ISP’s ASR 914 chassis fail during a heatwave due to third-party fans, the value of Cisco’s integrated module became irrefutable. While upfront costs are higher, the ASR-914-PWR-FAN= eliminates guesswork in thermal management—a critical factor when uptime SLAs dictate revenue. For networks prioritizing predictability over penny-pinching, this module isn’t optional; it’s insurance.
