Key technical data

Installation and acceptance

Before servicing D4K-12TP-RJ45, record existing wiring, port assignments, operating status and configuration where applicable. Use the manufacturer's installation procedure and the site's authorized maintenance window. Record the pre-change state so the equipment can be restored if the replacement does not pass acceptance.

After D4K-12TP-RJ45 is installed, check the relevant power, link, alarm and application behavior against the original baseline. File the serial number, final code, test result and any approved deviation together. Successful power-up alone does not prove functional equivalence.

Where this item fits

For D4K-12TP-RJ45, start with the equipment already installed and the role it performs in the network or cabinet. This field-replaceable card needs a compatible DRAGON MACH4x00 chassis, not a separate power supply. The visible type name identifies the enquiry; the actual site wiring, accessories and software determine whether the offer fits.

Do not assume D4K-12TP-RJ45 can substitute for another member of the D4K family. Similar model strings can represent different interfaces, environmental options, power inputs or software packages. Preserve the installed label photograph and the manufacturer's record with the purchase request.

Similar-looking model references

Specification and ordering checks

When requesting D4K-12TP-RJ45, provide quantity, condition requirements, the complete printed code and any available order number. Label all twelve cables and verify each port is recognized by the host after the card is fitted. Ask the supplier to state what is included, especially modules, connectors, optics, licenses, mounting parts or power components where applicable.

A quotation for D4K-12TP-RJ45 should separately identify the manufacturer's stated specification and any seller-proposed substitution. Check physical fit, electrical supply and connected media before approving that substitution. If the source code has an option placeholder, confirm the actual production revision on the device label.

Interface and system context

When evaluating Hirschmann D4K-12TP-RJ45, identify the connected host or neighboring equipment first. 12 FE/GE twisted-pair RJ45 ports; item 942155001. Document cable or module positions, the cabinet layout, and the normal operating state. This turns D4K-12TP-RJ45 from a text-only enquiry into a configuration that can be checked against the manufacturer's information.

For D4K-12TP-RJ45, note which components are included in the offered assembly. A switch base, optical module, wireless radio, connector, power unit or fan cannot be evaluated from its family name alone. Compare the actual interfaces and accessories with the site bill of materials before approving an alternative.

Replacement decision

The key replacement question for D4K-12TP-RJ45 is whether the installed function will be restored without changing the design intent. This field-replaceable card needs a compatible DRAGON MACH4x00 chassis, not a separate power supply. Keep photographs of the full label, any revision marking and the current network or wiring diagram in the service record.

Ask the supplier to confirm the exact D4K-12TP-RJ45 designation in writing. Label all twelve cables and verify each port is recognized by the host after the card is fitted. If a related-looking code is proposed, compare it as a separate variant and record the reason it is acceptable. After receipt, inspect physical condition and test the item in the intended host or network under the approved procedure.

Buyer handover

For D4K-12TP-RJ45, retain the written offer, manufacturer identification and received-item inspection. Clarify availability, warranty or return terms and whether the item is new, refurbished or a tested spare. A complete handover reduces the risk of ordering a similar-looking but unsuitable D4K variant.
