Ciena CN-PSM-DC400 4200 Power Supply Image 1

Ciena CN-PSM-DC400 400W -48V DC power supply module for the Ciena 4200 chassis.

The Ciena CN-PSM-DC400 is a 400W DC power supply module for the Ciena 4200 optical transport chassis, also carrying the part references B-720-0018-002 and WMP1BMANAA. It runs from a -48V DC feed, the standard telecom central-office and cabinet supply voltage, and slots into the CN 4200 chassis power bay alongside a second module for N+1 redundancy.

The CN 4200 platform is Ciena’s metro/regional DWDM and Ethernet transport chassis, and each shelf typically carries two PSM modules so a single supply failure doesn’t take the shelf down. The 400W rating covers a fully populated chassis running multiple optical line, amplifier and switching cards.

This is a common spares and replacement item for sites maintaining a CN 4200 estate on -48V DC power. Tech-Star (UK-based, shipped worldwide) checks every power module before it ships. Get in touch to confirm compatibility with your CN 4200 shelf.
