Huawei 03020DQY/WD22FEMA transmission and access equipment Telecom System Card / Module

The Huawei 03020DQY/WD22FEMA is an FMUA Fan Environment monitor board for Huawei transmission and access equipment. Parts in this range are ordered by their part number rather than by description, because several share a physical format and are told apart only by the number printed on the label. A part of this kind is held as a spare because a failure takes the function it serves out of use until it is replaced, and equipment of this generation is no longer supplied new by the manufacturer. Where a revision is marked, it forms part of the identification rather than being a batch code, because revisions are qualified against particular software releases. Match the part number and revision against the unit you are replacing before ordering. Tech-Star (UK-based, shipped worldwide) supplies Huawei hardware for maintenance and spares holding.
