Hirschmann BRS20-0600S2S2-STCX99HHSESXX.X.XX Standard-Temperature Single-Mode HL Replacement Planning with Full Order-Code Matching
Hirschmann BRS20-0600S2S2-STCX99HHSESXX.X.XX is the BRS20-4TX/2FX-SM-HL configuration of the Hirschmann BOBCAT family. Where an existing design specifies the HL single-mode version, replacing it with a generic six-port Ethernet switch can omit essential ordering details. This configuration retains four RJ45 ports and two fixed SC single-mode links at Fast Ethernet speed.
For spare-parts identification, record 942170027 alongside the complete configuration printed above. The short Type remains useful for the installed-equipment register.
A targeted replacement for fixed single-mode links
Confirm the remote optical interface before swapping the switch. Save the existing network configuration and record port assignments so that the hardware change can be followed by a controlled connectivity and management check.
Should an EEC model be ordered when the purchase request specifies this standard-temperature HL code?
Any change should be reviewed and stated on the quotation. The exact requested code remains the reference for checking environmental ratings and software configuration.

Network configuration requirements
When replacing this HL configuration, identify the network profile currently used by the plant. Belden lists EtherNet/IP, PROFINET, Modbus TCP and IEC 61850 MMS switch-model profiles. Ask the supplier to state the software revision and review any difference before planning the cutover of the single-mode connections.
Power checks for the selected hardware
Catalog supply: 2 x 12 VDC ... 24 VDC; listed power consumption: 7 W. A planned HL replacement should record the DC terminal identification before network cables are removed. Compare the proposed device and existing installation documentation, then confirm the supply arrangement during commissioning. Keep any wiring deviations visible in the maintenance record.
