HPE X712 Back To Front

The HPE X712 Back To Front (JG553-61101-RFB) is a refurbished fan tray for directing airflow in supported HPE networking equipment. Its back-to-front design moves air from the power side toward the port side, helping match the switch’s required airflow direction.

HPE describes the X712 as a high-volume airflow fan tray and lists it for the FlexFabric 5900CP switch JG838A. That switch requires two fan trays with the same airflow direction. This listing identifies the item as refurbished and uses the exact code JG553-61101-RFB.
