Hirschmann LRS42-7TX/3SFP/1C-HP Interface Schedule, Cabinet Conditions and Quotation Preparation Guide

Identify the exact hardware before quotation

Hirschmann LRS42-7TX/3SFP/1C-HP identifies Type LRS42-7TX/3SFP/1C-HP, part number 942328104. 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, PoE on up to 8 ports. 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.

Calculate the PoE budget from actual loads

List every powered device and its required class, then compare the combined demand with the documented switch budget and input supply. Include cable losses, startup demand and temperature derating where applicable. The switch consumption and available PoE output must not be treated as the same figure.

Prepare a useful RFQ

For Hirschmann LRS42-7TX/3SFP/1C-HP, 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.
