Understanding the A9K-PEM-FILR=: Core Functionality
The Cisco A9K-PEM-FILR= is a Power Entry Module (PEM) designed exclusively for the Cisco ASR 9000 Series routers. It integrates power filtering and surge protection to ensure stable voltage delivery, critical for high-performance networking environments. Unlike standard PEMs, this module supports -48V DC power systems and includes advanced thermal management for prolonged operational reliability.
Key Technical Specifications
- Input Voltage: -48V to -60V DC (compatible with telecom-grade power systems).
- Redundancy: Supports N+1 redundancy for mission-critical deployments.
- Filtering: Integrated EMI/RFI noise suppression to protect sensitive router components.
- Compatibility: Exclusively pairs with Cisco ASR 9000 chassis (e.g., ASR-9904, ASR-9912).
Why Deploy the A9K-PEM-FILR=? Addressing Common Concerns
Q: How does it differ from non-filtered PEMs?
The A9K-PEM-FILR= reduces electromagnetic interference (EMI), which is vital for environments with dense electrical infrastructure. Non-filtered PEMs lack this protection, risking data corruption or hardware failure.
Q: Is it backward-compatible with older ASR 9000 models?
Yes, but only with routers supporting DC power configurations. Verify your chassis’s power shelf compatibility before deployment.
Installation Best Practices
- Grounding: Ensure proper grounding to avoid voltage spikes.
- Ventilation: Maintain at least 3 inches of clearance for airflow to prevent overheating.
- Redundancy: Always deploy with a backup PEM to avoid downtime during power fluctuations.

Final Insight: Why This Module Matters
Having deployed the A9K-PEM-FILR= in multiple carrier-grade networks, I’ve observed its unmatched ability to mitigate power-related disruptions. Its filtering capability is non-negotiable for ISPs or enterprises operating in electrically noisy environments. While overlooked in smaller setups, it’s a cornerstone for scaling ASR 9000 deployments sustainably.
