Why a PoE card fails to be registered on S series switches

The ES0D0G48VA00 card is the PoE card for the S12700 and S7700, and the LE0DG48VEA00 card is the PoE card for the S9300. Possible causes of a PoE card registration failure are as follows:
No PoE power module is installed in the PoE power slot of the switch.
The PoE power module is not powered on.
The dual in-line memory module (DIMM) is faulty. For the handling methods, see "Fault Locating Guide - Card Registration Failure" in Huawei S Series Campus Switches Maintenance Guide.
