​​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.
