ASR-9903-PEC-FILR= Overview in Cisco’s High-End Routing Ecosystem
The Cisco ASR-9903-PEC-FILR= is a specialized hardware module for the ASR 9903 Router, part of Cisco’s ASR 9000 Series. The “PEC-FILR” suffix suggests it is a Power Entry Controller with Field-Replaceable Linecard Redundancy, designed to enhance power management and service continuity in mission-critical environments.
Technical Capabilities and Design Priorities
This module likely addresses two critical operational needs:
- Power redundancy: Supports N+N power supply configurations, enabling seamless failover during grid fluctuations or PSU failures.
- Hot-swappable maintenance: Allows replacement of power or fabric modules without disrupting traffic forwarding.
- Energy efficiency: Integrates with Cisco’s EnergyWise technology to dynamically adjust power draw based on load (e.g., 30–40% savings during off-peak).
Its design aligns with the ASR 9903’s role as a core/peering router, where uptime and energy costs directly impact profitability.
Key Use Cases for the ASR-9903-PEC-FILR=
The module is critical in deployments requiring zero downtime and energy-conscious operations, such as:
- Hyperscale data center interconnects: Ensuring uninterrupted 400G links between availability zones.
- Financial trading networks: Mitigating microsecond-level latency spikes caused by power hiccups.
- Government/military backbones: Meeting stringent SLAs for encrypted traffic (e.g., MACsec/IPsec).
For example, a cloud provider might deploy this module to guarantee 100Gbps encrypted tunnels between regions, even during localized power outages.
ASR-9903-PEC-FILR= vs. Standard ASR 9903 Configurations
Compared to base ASR 9903 setups, this module offers:
- Enhanced fault tolerance: Isolates power faults at the controller level, preventing chassis-wide reboots.
- Granular power monitoring: Provides real-time metrics per line card (voltage, current, temperature).
- Compliance with green initiatives: Meets ISO 50001 standards for energy management.
These features justify its premium cost for operators prioritizing operational resilience.

Why Power Infrastructure Is the Unsung Hero of Networking
After troubleshooting a data center outage caused by a $50 power supply, I’ve learned that the ASR-9903-PEC-FILR= isn’t just a part—it’s the difference between a minor log entry and a CEO’s midnight panic call. In core networking, redundancy isn’t about avoiding failures; it’s about ensuring failures don’t cascade. Hardware like this isn’t optional for serious operators—it’s the price of credibility.
