Hirschmann BRS20-20009999-TTDY99HHSESXX.X.XX: BRS20-20TX-EEC Selection and Replacement Guide for Twenty Copper Ethernet Connections
Hirschmann BRS20-20009999-TTDY99HHSESXX.X.XX is the BOBCAT BRS20-20TX-EEC configuration, catalog part number 942170082. Its twenty 10/100BASE-TX RJ45 ports support a copper Fast Ethernet network layout. The managed, fanless DIN rail unit is specified with a metal housing and a -40 to +70 °C operating range, making temperature and mounting conditions central to the selection process.

Replacing a dense copper-port switch
When matching an installed unit, retain the complete product code rather than ordering by twenty-port capacity alone. Compare the Type, supply arrangement, temperature requirement and existing management setup. Record which RJ45 links serve devices and which connect to other switches. A clear port map helps keep maintenance work aligned with the approved plant network.
Electrical and environmental checks
Published power data specifies two 12–24 V DC inputs and 15 W consumption. The housing has IP30 protection; a suitable enclosure is needed where the application calls for greater environmental protection. Relative humidity is listed at 1–95%, non-condensing. Evaluate actual cabinet temperature during operation, because the surrounding equipment and enclosure design determine the conditions experienced by the switch.

Fast Ethernet links and commissioning scope
The twenty RJ45 ports use 10/100BASE-TX, with a catalog twisted-pair range of 0–100 m per segment. The published port arrangement has no fiber slots. Before commissioning, compare the required speed and media with every link. The listed industrial profiles include PROFINET, EtherNet/IP, Modbus TCP and IEC 61850 MMS server / switch-model functions; verify required software support and preserve the approved configuration for the replacement process.
