How to Install HPE FlexFabric 12902E 1800W DC Power Supply Unit

• Power down and unplug the equipment before installation. Ensure you follow your data center’s safety procedures and wear appropriate PPE as required.
• Identify the correct hot-plug power supply bay or slot within the enclosure or server chassis compatible with the 12902E unit. Confirm that the chassis supports redundant DC power supplies and that there is an available slot.
• Remove the existing power supply, if present, by releasing the retention mechanism and carefully pulling the unit out of the bay. Handle the unit by its frame and avoid touching electrical contacts.
• Align the 12902E with the bay rails and slide it gently into place until the retention latch engages. Listen for a click indicating a secure installation, then ensure the unit sits firmly and is not loose.
• Connect the DC input cables to the power supply using approved cables and connectors per your data center standards. Route cables to avoid interference with airflow and other hardware, and secure them to prevent accidental disconnections.
• Power on the device and monitor the status indicators. Confirm that the supply reports healthy operation in your management interface, and verify that redundancy is functioning if a second power supply is present.
