Hirschmann BRS20-2400ZZZZ-STCY99HHSESXX.X.XX: BRS20-20TX/4SFP Network Design Guide for Copper Access Ports and Optical Inter-Switch Links
Hirschmann BRS20-2400ZZZZ-STCY99HHSESXX.X.XX is the catalog ordering identity for BRS20-20TX/4SFP, part number 942170057. The switch combines twenty 10/100BASE-TX RJ45 ports with four 100 Mbit/s SFP slots, giving twenty-four ports in total. Its fanless managed DIN rail design provides a single device to evaluate for a copper device network that also requires optical connections.

Separate access-port demand from optical-link demand
Use the twenty copper ports for the intended device and copper-link schedule, and define a separate list for the four SFP connections. Optical paths can connect different sections of a network when the chosen transceivers and fiber support the design. The catalog specifies 100 Mbit/s SFP slots here; module selection must match that requirement and the receiving endpoint.

Specify the optical components in the quotation
Fiber reach is determined by the supported SFP module and the installed optical path, not by the switch Type alone. Identify single-mode or multimode fiber, required distance, connector type and the existing remote optic. State module quantities and whether spare transceivers are required. This information lets a switch inquiry describe a complete intended connection rather than an unspecified optical slot.
Panel dimensions, power and configuration
The PC-ABS unit is listed at 109 × 138 × 115 mm and 1050 g. It operates from two 12–24 V DC inputs, with 16 W published consumption and a 0 to +60 °C operating range. Preserve space for copper plugs and safe fiber routing. Managed-network commissioning should include a port map, approved configuration and firmware requirements, with any required industrial profile checked against the offered device.
Check the offer against the installation
For an HKXY quotation, identify BRS20-20TX/4SFP, full product code and part number 942170057. Include switch quantity, required SFP modules, link distances and panel temperature. Send the installed label and software requirement if this is a replacement, and confirm accessories and delivery timing in the offered scope.
