      6ES7952-1AM00-0AA0 belongs to the Siemens S7-400 platform. Match the rack or station, front connector, adjacent modules, bus architecture and saved hardware configuration; a visually similar Siemens part is not automatically interchangeable.

      Before removal, isolate energy, save the project or channel parameters and identify every conductor and connector. After installation, check supply, diagnostics, communication and all affected functions under a controlled commissioning procedure.

      Technical notes

      This SIMATIC S7-400 MC 952 RAM memory card provides 4 MB capacity for compatible S7-400 CPUs. Retention depends on the CPU backup and power strategy, so a complete verified program backup is required before power-down or card removal. Record the CPU execution, firmware and existing card marking before replacement and use ESD-safe handling. After installation, confirm memory recognition, restore only the approved project and complete the documented controller restart and diagnostic checks.

      Exact Model & Electrical Configuration

      Verify the complete 6ES7952-1AM00-0AA0 marking, hardware release, product function and documented ratings. RAM contents depend on the CPU retention and backup strategy. The exact CPU execution, current program backup and approved power-down/card handling procedure must be confirmed before replacement. Preserve the installed connector, wiring and hardware configuration unless the approved engineering change specifically requires otherwise.

      Replacement & Functional Test

      Record the exact slot or rack position, labels, wiring, addresses, configuration and accessories before removal. After installation, confirm connector seating and diagnostics, then test every affected input, output, interface or CPU function using the approved machine or process test procedure.
