The Cisco A9K-DC-PEM-V2 is a Version-2 DC Power Entry Module (PEM) designed for the ASR-9000 Series routers. It provides robust, redundant DC power infrastructure with an input voltage range of about −40 to −72 VDC, supporting high availability and efficiency in service provider networks and data centers. This module is compatible with V2-compatible chassis such as ASR-9001, ASR-9006, ASR-9010, and other ASR-9000 systems, enabling modular power system scaling with redundancy and streamlined maintenance. Key Features & Benefits Supports DC input of −40 to −72 VDC, suitable for telecommunications and carrier-grade power environments. Version 2 (V2) PEM design for ASR-9000 V2 chassis – improved reliability and modularity. Redundancy: can be deployed in N 1 redundant configuration (DC power shelf / trays) for higher uptime. Shared / load-sharing power infrastructure in power trays; no strict power zones; designed so that adding more modules increases available power as needed. Designed for high MTBF, hot-swappable maintenance, and reliability in harsh DC power conditions.
