Siemens 6GK5491-2AC00-8AA2 is identified in Siemens conformity documentation as the SCALANCE X media module MM491-2LD. It belongs to the industrial communication hardware used with compatible SCALANCE X equipment. Because the available official record confirms the exact designation but does not expose a complete current configuration or lifecycle record, this page does not add connector counts, transmission distances, port speeds or lifecycle wording. Procurement review should match the complete suffix, MM491-2LD designation, host equipment, module slot and installed network documentation. Stockoems commercial terms cover condition, availability and warranty, with coordinated compatibility review, packaging and worldwide shipping.
Official Siemens conformity documentation confirms the complete part number and MM491-2LD designation. Connector configuration, transmission range, port speed and lifecycle wording are omitted because they were not confirmed in a current exact-product catalog record.
Condition, availability and warranty are Stockoems commercial terms, not Siemens manufacturer commitments.
