Applications
Smart Node Alarm Cards like the SNAC are used in telecom and network equipment enclosures to aggregate and relay alarm signals from installed modules or line cards back to a central network management system. They are common in carrier-grade and enterprise network infrastructure, particularly in DSL, T1/E1, and legacy DSLAM or multi-service access node (MSAN) platforms. The dual COM ports allow connection to local craft terminals or external alarm equipment, while the Ethernet port enables integration with IP-based network management systems (NMS) for remote alarm monitoring. These cards are typically sought by telecom network engineers and maintenance teams supporting legacy PDSi-based node equipment.
This GNP PDSi 1-503759A Smart Node Alarm Card (SNAC) has been inspected and is in good condition. The card is intact and shows normal light wear consistent with careful prior use. The dual COM ports and Ethernet port are present. Note that the faceplate is missing — please refer to the photos for a clear view of the card's current state.
