Identify the exact hardware before quotation
Hirschmann RED25-04002Z6TT-TDDY9HPE2SXX.X.XX identifies Type RED25-2TX/2SFP, part number 942137003. The manufacturer record describes it as a redundancy-focused managed industrial Ethernet switch. Procurement teams should retain the complete Type and, where present, the configured product code because a shortened family name does not define the same interface, software, environmental or power selection.
Plan the connected network
The recorded interface arrangement is 4 ports in total: 2 x 10/100 Mbit/s Twisted Pair / RJ45 ; 2 FE-SFP slot. Translate that statement into a port schedule showing each controller, remote I/O station, operator panel, camera or uplink. Confirm speed and media at both ends of every connection. This prevents a quotation based only on port count from overlooking connector type, optical reach or endpoint capability.

Specify optical components separately
SFP or fixed-fiber references require a complete optical plan. State fiber type, wavelength, connector, link distance and the remote interface, then identify compatible transceivers and patch leads separately. A switch with an optical position does not automatically include the transceiver needed for the project.
Review cabinet power and environment
The source lists 12-48 VDC (nominal), 9.6-60 VDC (range) and 24 VAC (nominal), 18-30 VAC (range); (redundant), an operating reference of -40 to +60 °C °C, and dimensions of 47 mm x 131 mm x 111 mm. Check the complete supply range, protective device, grounding, cabinet temperature and service clearance against current installation instructions. Published device dimensions do not include all cable bend and maintenance space.
Prepare a useful RFQ
For Hirschmann RED25-04002Z6TT-TDDY9HPE2SXX.X.XX, send HKXY the exact Type, part number, quantity and destination. Add the required delivery date, project environment, interface schedule and documentation needs. Ask the quotation to distinguish included hardware from separately ordered power supplies, media modules, transceivers, connectors or mounting accessories.
Documentation for lifecycle support
Keep the quotation, delivered label photograph, manufacturer documents and final network drawing under the same equipment reference. Record separately supplied accessories by their exact part numbers. A complete lifecycle file helps purchasing distinguish the approved configuration from visually similar family members and supports faster troubleshooting during planned maintenance.
