About This Part
The Alcatel 3HE03661AA is a critical DC Power Entry Module (PEM-3) designed specifically for the Alcatel 7750 Service Router (SR) series, particularly the 7750 SR-7 chassis. This module serves as a primary power interface, converting incoming DC power to the required operational voltages for the router's internal components. As a PEM-3, it is engineered for high reliability and efficiency, ensuring stable power delivery to maintain continuous operation of high-performance routing and switching functions. It typically accepts a nominal -48V DC to -60V DC input, crucial for telecom and data center environments that rely on robust DC power infrastructure. The design emphasizes fault tolerance, often supporting redundant configurations to prevent single points of failure within the network core, thereby safeguarding network uptime and service continuity. Deployment of the Alcatel 3HE03661AA is integral to the operational integrity of the Alcatel 7750 SR-7, typically occupying a designated power slot within the chassis, such as slot position 1. This module is essential for telecom operators, internet service providers (ISPs), and large enterprise data centers that leverage the 7750 SR platform for core routing, edge routing, and aggregation services. It addresses the critical need for uninterrupted power in environments where network downtime is unacceptable, supporting applications ranging from broadband aggregation to MPLS services and carrier Ethernet. By ensuring a stable and redundant power supply, the 3HE03661AA helps maintain the high availability required for mission-critical network functions, serving as a direct replacement for failed units or an upgrade to enhance power resilience in existing deployments.
