Hirschmann LRS40-7TX/3SFP/1C Product Details for Maintenance Teams, System Integrators and Industrial Procurement

Identify the exact hardware before quotation

Hirschmann LRS40-7TX/3SFP/1C identifies Type LRS40-7TX/3SFP/1C, part number 942328003. The manufacturer record describes it as a LEMUR lite-managed DIN-rail 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 7x FE/GE TX, 3x FE/GE SFP, 1x FE/GE Combo. 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.

Technical identity and installation data

Review cabinet power and environment

The source lists 24 VDC, an operating reference of -40 to +60 °C °C, and dimensions of 68x135x118 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 LRS40-7TX/3SFP/1C, 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.

Replacement assessment

A matching port count alone does not establish interchangeability. Review enclosure space, connectors, supply range, environmental limits, management level and project approvals together. Where an existing unit is being replaced, photograph its label and wiring, export available settings, and record the reason for replacement before disconnecting the installed device.
