Supply & Industrial Networking Update | August 11, 2026

Industrial Ethernet projects are moving beyond basic Gigabit access as machine cells, vision systems, edge computers and redundant fiber rings generate more traffic at the control-cabinet level. This is increasing interest in high-density, fanless DIN-rail switches that combine conventional copper access ports with faster optical uplinks. One configuration receiving procurement attention is the Hirschmann BRS50-00242Q2Q-ETDZ99HHSEAXX.X.XX BOBCAT managed switch.

This exact configuration is the 24-port member of the BRS50 all-Gigabit family. It combines 20 copper ports with four tri-speed SFP slots and should not be confused with the smaller 12-port BRS50-00122Q2Q configuration, even though both official generated data sheets display the BOBCAT configurator part number 942170999.

Configuration Breakdown: BRS50-00242Q2Q-ETDZ99HHSEAXX.X.XX

Belden's official generated technical data sheet identifies the following hardware and environmental configuration:

• Platform: Hirschmann BOBCAT BRS50 managed industrial Ethernet switch.

• Total ports: 24.

• Copper access: 20 x 10/100/1000BASE-TX RJ45 ports.

• Fiber uplinks: 4 x SFP slots supporting 100, 1000 or 2500 Mbit/s, arranged as two uplink groups of two slots.

• Power input: two 12-24 VDC inputs through the power and signal-contact terminal block.

• Power consumption: 20 W according to the generated data sheet.

• Operating temperature: -40°C to +70°C.

• Construction: metal housing, DIN-rail mounting, IP30, conformal coating on the PCB.

• Dimensions and weight: approximately 123 x 140 x 115 mm and 1.62 kg.

• Additional interfaces: USB-C for local management and device replacement, plus one digital input.

Why Four 2.5 Gigabit-Capable SFP Uplinks Matter

The four SFP slots are not ordinary fixed-speed Gigabit uplinks. They can operate at 100 Mbit/s, 1 Gbit/s or 2.5 Gbit/s when paired with a supported Hirschmann transceiver. This gives engineers a migration path from legacy Fast Ethernet fiber to Gigabit and 2.5 Gigabit backbones without changing the switch chassis.

For a 20-port copper access layer, the higher uplink rate can reduce oversubscription when several cameras, controllers, HMIs or edge devices communicate simultaneously. The four slots also support designs that need separate production, supervisory and redundant ring connections. SFP modules are selected separately according to fiber type, distance, speed and temperature requirement; the full switch order code does not by itself specify the optical transceivers.

Managed Networking, Redundancy and TSN

The HHSEA software configuration provides the advanced managed feature set represented in the official data sheet. Published capabilities include VLAN and QoS functions, IGMP snooping and querying, link aggregation, RSTP, MSTP, Media Redundancy Protocol, HIPER-Ring, SNMP management, secure web and SSH access, SFP diagnostics and OPC-UA server support.

Belden also lists TSN 802.1Qbv support on designated interfaces. TSN capability should be treated as part of an engineered system rather than a plug-and-play performance claim. End devices, traffic classes, time synchronization, HiOS configuration and the complete network path must all be reviewed before deterministic traffic behavior can be expected.

Understanding 942170999: Configurator Number Versus Exact Variant

942170999 is shown by Belden as the BOBCAT configurator part number. It is used across many customized BRS variants and is not sufficient to distinguish this 24-port metal-housing switch from other port counts, temperature grades, housings, approvals or software levels.

Procurement documents should therefore retain the full string BRS50-00242Q2Q-ETDZ99HHSEAXX.X.XX. A quotation that lists only 942170999 should be supported by the generated configuration data sheet or manufacturer order confirmation. Buyers should also check whether a more specific hyphenated material-number suffix is assigned for the final manufactured variant.

Installation and Replacement Planning

The 123 mm cabinet width and 20 W power consumption require more panel space and thermal planning than the compact 12-port BRS50 variant. Engineers should verify DIN-rail clearance, cable bend radius, terminal access and ventilation before using the model as a replacement for a narrower legacy OpenRail switch.

The two power inputs can support redundant DC feeds, but redundancy depends on correct upstream power architecture and alarm-contact wiring. Configuration backup, firmware compatibility, SFP support and ring protocol settings should be documented before migration. A bench test is recommended when the new switch will replace an active ring manager or TSN participant.

Current Supply Chain Availability

HONGKONG XIEYUAN TECH CO., LIMITED is supporting enquiries for BRS50-00242Q2Q-ETDZ99HHSEAXX.X.XX, the BOBCAT configurator family 942170999 and related Hirschmann BRS50 variants. Stock-oriented sourcing and fast-delivery coordination are available for industrial network expansion, shutdown replacement and installed-base support.

Lead time depends on the complete configuration, quantity, software level, approvals and SFP requirements. Buyers should request confirmation of the full order string, housing, temperature range and port map before approving a substitute.

Buyer's Verification Checklist

1. Confirm 24 total ports: 20 RJ45 plus four tri-speed SFP slots.

2. Verify the full BRS50-00242Q2Q-ETDZ99HHSEAXX.X.XX code, not only 942170999.

3. Check the metal housing, -40°C to +70°C range and conformal coating requirement.

4. Confirm 12-24 VDC power design, cabinet space and 20 W load.

5. Select compatible SFP transceivers separately.

6. Review HiOS, redundancy and TSN configuration before commissioning.
