Genband 805-0115-141 PAC-2 Power and Alarm Card

The Genband 805-0115-141, identified as the PAC-2 (Power and Alarm Card), is an essential infrastructure component for the Genband G9 Converged Gateway chassis. This module is engineered to provide integrated power distribution and comprehensive system monitoring functions within a high-availability telecommunications environment. The PAC-2 acts as a centralized interface for DC power input, ensuring regulated distribution to the system backplane and protecting the internal modules from overcurrent and voltage fluctuations. Beyond its power management capabilities, the PAC-2 serves as the primary hardware interface for environmental and system alarm monitoring. It features physical ports for dry contact alarms and external sensor inputs, allowing the G9 platform to communicate critical status alerts (such as temperature thresholds, fan failures, or power loss) to a Network Operations Center (NOC) or an external alarm panel. The module supports redundant configurations, typically installed in pairs within the G9 chassis to prevent a single point of failure in power delivery or system telemetry.

The hardware architecture of the 805-0115-141 includes integrated LED status indicators for real-time visual diagnostics of the power feeds and alarm states. It is designed for continuous 24/7 operation in carrier-class central offices, meeting NEBS requirements for reliability and electromagnetic compatibility. The card connects directly to the chassis midplane, facilitating seamless integration with the system control boards for centralized management of power parameters and alarm logs.
