Linecard CAT 126-3375-003 Power Supply Repair Service

Professional diagnostic and board-level repair service for this Linecard CAT 126-3375-003 Power Supply.

Linecard CAT 126‑3375‑003 is a modular industrial power supply unit used in high‑current linecard chassis for data‑center and telecom equipment. Common failure modes for this class include degraded MOSFETs or IGBTs, blown electrolytic capacitors on the DC output stage, and overheating of the internal heat sink due to inadequate airflow. First‑check steps: verify that the input AC voltage is within spec and that the unit receives power; inspect the PCB for bulging or cracked capacitors and check the temperature of the heat sink under load; review any error codes from the host system’s diagnostic interface for indications of output voltage dropout or over‑current protection trips.
