Ordering Hirschmann BRS20-08009999-STCY99HHSEAXX.X.XX: Eight RJ45 Fast Ethernet Ports and Configuration Checks for the BRS20-8TX-2A Switch
Hirschmann BRS20-08009999-STCY99HHSEAXX.X.XX corresponds to BRS20-8TX-2A, the eight-port BOBCAT managed DIN rail switch listed as part number 942170104. The complete product code distinguishes this preset configuration from other BRS20-8TX versions that can share the same enclosure and port count. Use that code throughout quotation and purchase documents when the project calls for the -2A Type.

Do not shorten the ordering reference
The eight physical interfaces are 10/100BASE-TX RJ45 connections. Matching those interfaces establishes only the basic media layout, not equivalence between ordering variants. Keep the SEAXX portion of the supplied code and ask the supplier to confirm the exact delivery configuration. Do not infer an additional hardware feature or a specific software entitlement merely from the -2A shorthand.

From a parts list to an installation plan
The fanless housing is PC-ABS with an IP30 protection rating. Check that the intended enclosure provides the environmental protection the installation requires. Review the 0 to +60 °C operating range, local heat sources and terminal accessibility together; a cabinet that accepts the mounting dimensions may still need a different environmental arrangement.
Questions to settle during replacement review
Which current port carries the upstream connection? Are all eight interfaces already assigned? Is the current switch configuration backed up and approved for transfer? Answers to these questions make the requested replacement more precise. The manufacturer lists a six-pin terminal block for power/signaling and a separate two-pin digital input, which should be included in the wiring review.
Request a configuration-specific HKXY quotation
For BRS20-8TX-2A, quote part 942170104 together with the full product code rather than an abbreviated family name. HKXY can prepare an enquiry using your quantity, device-label photographs, firmware requirements and destination. Confirm accessories, documentation and lead time before ordering.
