Hirschmann BRS20-04009999-STCX99HHSESXX.X.XX BRS20 Four-Port HL Procurement with Copper Port Mapping and Approval Review
Hirschmann BRS20-04009999-STCX99HHSESXX.X.XX is the BRS20-4TX-HL configuration of the Hirschmann BOBCAT family. For an installed four-port BRS20 network, preserving the HL order variant can matter as much as preserving the Ethernet connections. This standard-temperature configuration provides four RJ45 ports in a fanless DIN rail device.
For spare-parts identification, record 942170023 alongside the complete configuration printed above. The short Type remains useful for the installed-equipment register.

Four-port replacement with the HL option
Before disconnecting an existing switch, label each cable and record its network role. Keep the full replacement code alongside the saved configuration, so purchasing can compare the proposed hardware with the engineering-approved bill of materials.
Software selection alongside the hardware
For an HL replacement, compare the software baseline as well as the physical connections. Belden lists EtherNet/IP, PROFINET, Modbus TCP and IEC 61850 MMS switch-model profiles. Preserve the profile used by the existing system and confirm compatibility before accepting a change to the replacement configuration.
Is the HL version also the extended-temperature EEC version?
Not in this listing. Its published operating range is 0 to +60 °C. An EEC-HL requirement should be quoted as its own complete configuration.
Document the installed connections
- Photograph the installed label and tag the four RJ45 leads before disconnecting anything.
- Compare the standard-temperature HL code and software revision with the replacement offered.
- Restore approved settings, verify communication with all connected devices and retain the completed port map.
Purchasing details for the exact model
