Hirschmann BRS30-0804OOOO-STCY99HHSESXX.X.XX: A Compact BOBCAT Platform for Copper-to-Fiber Networks

The Hirschmann BRS30-0804OOOO-STCY99HHSESXX.X.XX is a fanless, DIN-rail managed industrial Ethernet switch from the Hirschmann BOBCAT family. Its combination of eight Fast Ethernet copper ports and four SFP uplinks suits control cabinets that need to aggregate local devices and carry traffic over fiber to another production area, control room or network layer.

This ordering code should be reviewed as a complete configuration, not simply as a generic BRS30 switch. Port count, temperature class, software package, approvals and revision details can affect replacement and expansion projects.

Where this 8TX/4SFP layout fits

A practical use case is a machine or process cell with several copper-connected endpoints and more than one fiber path. The four SFP positions allow the network designer to separate uplink, ring and expansion links without consuming the eight local RJ45 connections. Before selecting optics, document the connector, fiber type, wavelength, distance and speed at both ends of every link.

• Eight RJ45 ports provide local Fast Ethernet connectivity for PLCs, HMIs, drives and other cabinet devices.
• Four SFP slots support flexible 100/1000 Mbit/s optical uplinks; transceiver type must match fiber, wavelength and distance.
• Managed functions include VLAN, QoS, SNMP, RSTP/MRP and diagnostic tools for maintainable industrial networks.
• Dual 12-24 V DC inputs support redundant power planning, subject to the final cabinet wiring design.

Verified configuration snapshot

The specifications above follow the model-specific Belden/Hirschmann catalog record for product code BRS30-0804OOOO-STCY99HHSESXX.X.XX. Confirm current documentation and the offered hardware/software revision before ordering.

Replacement and commissioning questions buyers should ask

For a maintenance replacement, export the existing switch configuration before the outage and record VLANs, ring roles, management addresses, SFP assignments and security settings. A matching physical port layout does not automatically guarantee configuration compatibility with another BOBCAT or legacy Hirschmann model.

For a new cabinet, verify rail space, 12-24 V DC power feeds, grounding, ambient temperature and cable routing. The switch, SFP modules and fiber patch leads should be listed as separate bill-of-material items so that quotations can be compared on the same scope.

Related BOBCAT models for comparison

The BRS30 family also includes configurations with higher copper-port counts, while BRS20, BRS40 and BRS50 variants address different port and uplink arrangements. Compare the full ordering codes rather than choosing by family name alone. Common searches include BRS30-1604OOOO-STCY99HHSESXX.X.XX for 16TX/4SFP and BRS30-2004OOOO-STCY99HHSESXX.X.XX for 20TX/4SFP.

What to include in an RFQ

Send the exact keyword Hirschmann BRS30-0804OOOO-STCY99HHSESXX.X.XX, required quantity, destination country and requested delivery date. For replacement work, attach a clear nameplate photo and state whether SFP transceivers, terminal blocks or a configuration accessory are also required. HKXYTECH can then check availability and quote the requested scope without treating optional accessories as part of the base switch.
