The Arris D5 CPCI-DC-6U is the redundant DC power supply unit (PSU) module designed for the Arris D5 Universal Edge QAM (UEQ) chassis.

It is specifically built for cable headend and hub sites that utilize -48 VDC station power (battery plants) rather than commercial AC power.

Key Specifications
Form Factor: 6U High, CompactPCI (cPCI) standard compliant (PICMG 2.11).

Input Voltage: -48 VDC nominal. It typically operates within a range of -36 VDC to -72 VDC to accommodate battery discharge curves.

Redundancy: Hot-swappable and supports N+1 redundancy (usually 2 units per chassis), allowing for seamless failover if a power feed or module fails.
