Hirschmann BRS20-2400ZZZZ-TTDY99HHSESXX.X.XX: BRS20-20TX/4SFP-EEC Technical Guide for Wide-Temperature Copper and Optical Network Cabinets
Hirschmann BRS20-2400ZZZZ-TTDY99HHSESXX.X.XX refers to BRS20-20TX/4SFP-EEC, part number 942170058. This managed BOBCAT configuration offers twenty copper 10/100BASE-TX RJ45 ports and four 100 Mbit/s SFP slots. Its metal housing, DIN rail mounting and -40 to +70 °C operating specification are relevant to installations where both a larger port schedule and extended temperature capability must be addressed.

Optical-link compatibility comes first
Before approving an optical network bill of materials, establish the supported SFP type, speed, fiber medium, wavelength, connector and remote endpoint. The slots are listed at 100 Mbit/s. Their presence does not define the maximum optical distance; use the selected module's specifications and the actual link budget. Check each module's temperature rating against the intended environment as well.
Fit the switch into the cabinet design
Published dimensions are 123 × 140 × 115 mm. Plan space for the twenty RJ45 connections, optical patch leads and accessible power terminals. The catalog gives two 12–24 V DC supply inputs and 16 W consumption. Both enclosure heat and fiber routing deserve review when many connections are concentrated in one DIN rail location.
Document the managed installation
Create a port schedule covering local devices and all connections to neighboring switches. The RJ45 links operate at 10/100 Mbit/s and have a stated twisted-pair segment range of 0–100 m. The profile list includes EtherNet/IP, PROFINET, Modbus TCP and IEC 61850 MMS server / switch-model functions. Confirm the necessary firmware and retain the approved configuration so a future replacement can be matched accurately.
Request the specified configuration from HKXY
Submit the complete code, BRS20-20TX/4SFP-EEC and part number 942170058 to HKXY with the quantity required. Define the SFP scope, fiber distances, operating-temperature requirement and documentation needs. For an installed-system spare, include a label photograph and software reference, then confirm the offered configuration and delivery scope.
