Huawei 03033WJF Power Supply Module (STL6CPWRE01 / STL6CPWE03) for OceanStor Dorado 5300 V6

The 03033WJF Power Supply is a replacement power module for the Huawei OceanStor Dorado 5300 V6 all-flash storage system, supplied under model codes STL6CPWRE01 and STL6CPWE03. In a production array, a failed PSU is not a small problem — it removes redundancy, triggers alarms, and leaves the enclosure one fault away from an outage. This module restores that redundancy in minutes.

Key Specifications

Restore Redundancy Before It Costs You an Outage

Dorado 5300 V6 enclosures are designed to run with redundant power feeds, so that a single module or feed failure does not interrupt service. Once one module fails, that protection is gone: the remaining module carries the full load, runs hotter, and any second event takes the array down. Keeping a spare 03033WJF on the shelf — or replacing a failed unit immediately — is the cheapest insurance in the rack.

Hot-Swap Service Without Downtime

The module is hot-swappable in a redundant configuration. With the array running on the healthy module, you release the latch, slide the failed unit out, seat the replacement, and confirm the status LED and management alarm clear — no scheduled maintenance window required. Always verify the remaining module is healthy before starting the swap.

Genuine Huawei Module, Correct Telemetry

Third-party power modules often power up but fail to report correctly to the storage management plane, leaving you with phantom alarms or missing power telemetry. This is a genuine Huawei module, so the enclosure recognizes it, fan and power thresholds report accurately, and firmware updates apply as expected.

Confirm the Variant Before Ordering

The 03033WJF is supplied under two model codes, STL6CPWRE01 and STL6CPWE03. Before ordering, compare the code on your existing module’s label with the listing — mixing variants in the same enclosure can cause imbalance alarms. If you are unsure, send us a photo of the label and we will confirm fitment.
