Hirschmann RED25-04002T1TT-TDDY9HPE2SXX.X.XX Interface Schedule, Cabinet Conditions and Quotation Preparation Guide
Identify the exact hardware before quotation
Hirschmann RED25-04002T1TT-TDDY9HPE2SXX.X.XX identifies Type RED25-4TX, part number 942137002. 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: 4x 10/100 Mbit/s Twisted Pair / RJ45. 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.
Check copper cabling and endpoint speeds
Confirm cable category, connector condition, segment length and the supported rate of each attached device. Auto-negotiation does not correct unsuitable cabling or an incompatible endpoint. Keep the accepted port map with the equipment record so commissioning and later replacement work use the same assumptions.

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 RED25-04002T1TT-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.
Commissioning record
Before energizing the installation, compare the delivered label with the approved purchase record and current manual. Save the port assignment, software or configuration status, supply measurements and acceptance results. This evidence gives maintenance teams a dependable baseline and reduces ambiguity when a future replacement or network expansion is requested.
