Description
The Ciena CN-PSM-DC400 is a high-performance DC power supply module engineered for use in Ciena networking systems, particularly within carrier-grade and enterprise environments. Designed for reliability and efficiency, this module provides a steady 400W of DC power to support critical network operations. It features a compact, plug-in form factor that allows for easy installation and replacement within compatible Ciena chassis. The durable metal enclosure and front-facing status indicators ensure both physical protection and immediate visibility into operational status.
This unit supports a -48V DC input and is built to meet stringent telecom-grade power requirements, making it suitable for deployment in mission-critical infrastructure. Integrated thermal management helps maintain optimal operating temperatures, while built-in protection mechanisms guard against over-voltage, over-current, and thermal overloads. The CN-PSM-DC400 is compatible with a range of Ciena platforms, including the 6500 series, and is ideal for those looking to maintain or expand existing Ciena systems with cost-effective, pre-owned hardware. Each used unit is typically tested for full functionality and may show minor cosmetic wear consistent with previous use.
