C111178 Nokia Nokia Optical Transport Power Supply

The Nokia C111178, also identified as the PSC6-AB, is a power supply card designed to provide regulated DC power to Nokia optical transmission and network infrastructure equipment. This module delivers reliable power conversion and distribution within multi-slot chassis systems, ensuring stable operation of line cards and system modules.

The PSC6-AB is typically deployed in Nokia’s optical networking platforms, where it serves as part of a redundant power architecture supporting carrier-grade telecommunications infrastructure. These power supply cards are essential components in systems requiring continuous uptime and hot-swappable maintenance capabilities.

As a legacy Nokia component, the PSC6-AB may be associated with discontinued or end-of-life optical transport platforms. However, it remains a sought-after spare part for operators maintaining existing network deployments where like-for-like replacement is required.
