Assign the mixed-speed copper interfaces of Hirschmann BRS30-20042T2T-STCY99HHSESXX.X.XX
Hirschmann BRS30-20042T2T-STCY99HHSESXX.X.XX is the Hirschmann BRS30-24TX BOBCAT managed DIN rail configuration with 20 10/100BASE-TX RJ45 ports and four 10/100/1000BASE-TX RJ45 ports. The catalog specifies an operating temperature range of 0 to +60 °C. Identify the unit by its complete Product code and part number 942170087 when planning an installation or requesting a repeat order. The interface arrangement, environmental values and documented software functions below define the selection more precisely than a family name alone.
Reserve the higher-rate copper interfaces deliberately
The twenty-four RJ45 interfaces comprise twenty 10/100BASE-TX ports and four 10/100/1000BASE-TX ports. A design should identify which connections need the higher-rate positions before allocating all remaining devices. Include links to the surrounding network and any redundancy connections in that allocation. The total port count does not mean that twenty-four Gigabit endpoints can be connected at Gigabit speed. Review traffic across shared connections and confirm that the connected devices support the intended operating rates. Label the cable destinations and record normal speed and duplex indications after commissioning. If a cable is later moved, check the new port capabilities against the equipment requirement rather than relying on an identical connector shape. Preserve the accepted settings and port map with the full Product code so replacement and expansion work has a reliable baseline.
Include installation details in the equipment schedule
The manufacturer lists 16 W power consumption and pc-abs housing. The supply specification is 2 × 12–24 V DC. The published enclosure dimensions are 109 mm x 138 mm x 115 mm. The specified device weight is 1160 g. The enclosure is specified for DIN rail mounting and IP30 protection. Leave practical access to the connection area when arranging neighboring equipment. Check the manufacturer wiring instructions when selecting and connecting the DC supply, and record the arrangement where both inputs are used. Include connected cable space in the layout rather than reserving only the enclosure dimensions. Keeping the mechanical data and connection requirements beside the full code helps panel builders and maintenance staff work from the same equipment definition.

Commission the port roles with the actual equipment
Label the cable destinations before testing. Verify negotiated copper link speed and duplex settings against the equipment requirements, and check optical links separately where fitted. A link indication is one useful observation, but acceptance should also cover the communication that the machine or installation depends on. If redundancy is part of the design, test the configured behavior with the participating devices and retain the results. Identify spare interfaces in the final drawing rather than leaving their role ambiguous. This gives later service personnel a documented starting point when a connection or application changes.
What the receiving team should verify
Compare the delivered label with Hirschmann BRS30-20042T2T-STCY99HHSESXX.X.XX and part number 942170087. Check the supplied items against the accepted quotation, including separately listed accessories. Retain the manufacturer documents used by the installation team and identify the device location in the equipment register. Before putting the unit into routine service, confirm authorized management access and the communication required by the application. Keep the accepted configuration with the full product identity so a future replacement request has both the hardware reference and the settings associated with the installed network.
Monitoring a copper network across service visits
The management feature list includes HTTPS, SSHv2, SNMP v1/v2/v3 and LLDP, while diagnostics provide copper cable testing, link-speed and duplex monitoring, event logging and port mirroring. Choose which information the maintenance team needs and where it will be retained. A logged event is easier to interpret when port destinations and recent configuration changes are known. HIPER-Ring, MRP and RSTP support planned redundancy arrangements, subject to correct configuration across the network. Acceptance should confirm the selected arrangement rather than simply checking that all link LEDs are illuminated.
Configuration files belong with the machine documentation
The documented configuration tools include USB-C management support, XML-based configuration files and automatic configuration undo. Remote configuration backup when saving is also listed. Select the backup method used by the site and test the procedure during commissioning. Store the accepted file with the machine reference and the full switch code, and record later authorized changes. A file without a clear device association can be as difficult to use as a missing backup. Identify service accessories separately if the maintenance procedure depends on a particular cable or adapter. Keep a dated record of accepted configuration changes.
