What to Confirm Before Ordering Hirschmann D4K-12TP-RJ45 for an Industrial Network Project
Confirm the exact modular component
Hirschmann D4K-12TP-RJ45 identifies the Hirschmann DRAGON MACH4000 field-replaceable media module, model D4K-12TP-RJ45, part number 942155001. The manufacturer record describes it as: DRAGON MACH4x00 media module with 12 x FE/GE TX ports; field-replaceable. Keep the model and part number together because this item is a chassis component or accessory, not a complete operational switch.

Match the parent DRAGON MACH4000 system
Confirm the exact DRAGON MACH4000 or DRAGON MACH4500 chassis, available slot and accepted hardware or software revision before ordering. A similar module faceplate does not prove electrical, mechanical or system compatibility. Photograph the chassis label and existing module arrangement.
Review interface, power and mechanical data
The saved manufacturer data lists interfaces as 12 x 10/100/1000 Mbit/s RJ45 sockets für TP cable, auto-crossing, auto-negotiation, auto-polarity, operating supply as power supply via the backplane of the switch, power reference as 15 W, and dimensions of 220 mm x 334 mm x 23 mm. Check rack clearance, airflow, slot position, transceiver or cable needs and the complete installed load rather than reviewing one module in isolation.

Build the complete bill of materials
List the chassis, management or routing engine, media modules, power supplies, fan unit, blanking panels, SFP transceivers, patch leads and mounting accessories as separate line items. Ask the quotation to state what is included so a panel, power module or line card is not mistaken for a complete switch system.
Replacement and maintenance planning
Before removal, back up the current switch configuration and record the installed slot, adjacent modules, LED state, cabling and fault symptoms. Follow the approved shutdown, hot-swap, ESD and site safety procedure appropriate to the exact component. Retain the removed label for comparison with the delivered item.
Prepare a component-specific RFQ
Request Hirschmann D4K-12TP-RJ45, part number 942155001, with quantity, destination and target delivery date. Include the parent chassis, installed slot, full module inventory, system release and required documentation. For expansion work, add the port plan, expected traffic, transceiver types and redundancy design where applicable.
Receipt and lifecycle record
At receipt, verify the delivered part number, hardware revision and packing contents before installation. Store label photographs, acceptance checks, configuration backups and the approved bill of materials under the parent switch asset so later maintenance can distinguish the accepted build from nearby D4K variants.
Technical reference: manufacturer source for D4K-12TP-RJ45. Verify current documentation and the delivered revision before final engineering approval.
