Choose the Alternative High-Speed Module Arrangement for Hirschmann MSP40-00200SCY999HHE2AXX.X.XX MSP40 Layer 2 Advanced Industrial Ethernet Base
Hirschmann MSP40-00200SCY999HHE2AXX.X.XX identifies Type MSP40-20-2A, part number 942076012. The MSP40 base supports modular Gigabit networking with alternative high-speed uplink arrangements. The exact record describes sixteen Gigabit ports plus four 2.5-Gigabit ports, or sixteen Gigabit ports plus two 10-Gigabit ports. These are module-dependent alternatives, not port groups that can be added together or assumed to be fitted when ordering the base.

Choose one supported assembly before requesting supply
Define which high-speed arrangement the project requires and specify the compatible media modules. Record copper or optical interfaces and any transceivers separately. A base reference establishes the selected platform and HiOS Layer 2 Advanced software, but the complete module schedule determines the actual connections available to the network.

Distinguish delivery scope from platform capacity
The documented scope includes the backplane and power module, terminal blocks and safety information. It does not confirm delivery of all Ethernet modules. Ask an offer for a complete switch assembly to list the module references, quantities and positions. For base-only replacement work, identify existing modules that must remain compatible.
Review a complete power and cabinet schedule
This exact selection specifies 24 V DC with an 18–32 V input range, IP20 and 0 to +60 °C operation. The 19 W base consumption excludes media-module and PoE loads. Use the chosen assembly for supply calculations, and allow cable access beyond the 314 × 148 × 142 mm base dimensions.
Information for configuration-specific supply
Send HKXY the full Layer 2 base code, quantity and destination. Specify the preferred uplink arrangement and module list, with required documents, so the quotation describes a clearly defined assembly rather than theoretical capacity.
