Identification & compatibility checks
- Photograph manufacturer, full model number, revision, serial/date codes, connector faces, and included brackets or cables before installation.
- Confirm electrical interface, connector pinout, physical dimensions, power requirements, firmware/driver support, and the host device’s documented compatibility.
- Do not infer compatibility from a shared brand, socket silhouette, connector shape, or marketing family name. Revisions and regional SKUs may differ.
- When a unit’s identity is uncertain, compare component markings against the manufacturer manual and avoid applying power until the pinout and condition are known.
Context & archival notes
