Hirschmann BRS20-0600M2M2-STCX99HHSESXX.X.XX Multimode Fiber Replacement Checks for the Standard-Temperature 4TX/2FX-HL Model
Hirschmann BRS20-0600M2M2-STCX99HHSESXX.X.XX is the BRS20-4TX/2FX-HL configuration of the Hirschmann BOBCAT family. A six-port switch may have fixed fiber, removable optics or only copper connections. This HL configuration specifically combines four RJ45 ports with two fixed multimode SC ports, so optical interface identification is central to replacement planning.
Use Type BRS20-4TX/2FX-HL together with numeric part 942170025 when comparing the supplier offer with the engineering request.

Replace the optical variant as well as the port count
Record the existing cable labels, SC patch lead arrangement and remote switch model before preparing a replacement. Match the configuration and review any location-specific approval requirements independently of the Ethernet link specification.
Network configuration requirements
A maintenance replacement may need to preserve the controller-facing integration as well as the multimode fiber links. Check the installed software against the catalog references to EtherNet/IP, PROFINET, Modbus TCP and IEC 61850 MMS switch-model profiles, then document any proposed change before it reaches the site.
Can a single-mode SC version use the same multimode installation?
It should not be assumed. The SC connector shape can be the same even when the optical interface and required fiber are different.
Document the installed connections
Identify the standard-temperature HL version from its label before ordering the spare. Record both multimode SC destinations and all four local RJ45 assignments. After installation, check the applied management settings and test the intended copper and optical paths before returning the cabinet to service.
