Hirschmann BRS20-1000S2S2-TTCX99HHSESXX.X.XX Single-Mode Fiber and Eight-Port Copper Selection for an Extended-Temperature EEC-HL Industrial Network
Hirschmann BRS20-1000S2S2-TTCX99HHSESXX.X.XX is the BRS20-8TX/2FX-SM-EEC-HL configuration in the Hirschmann BOBCAT range. Eight copper device connections and two fixed single-mode SC fiber ports make this a specific ten-port Fast Ethernet selection. Its EEC-HL identity should remain intact when an engineering request passes from network design to purchasing, particularly where temperature and installation documentation are separate acceptance requirements.
Start with the installed fiber route
The optical connections are fixed 100BASE-FX single-mode interfaces, not interchangeable SFP slots. Record the remote switch interface, fiber type, termination and measured link loss. The matching SC connector alone cannot establish compatibility; compare both optical endpoints before accepting a replacement or adding a new branch to the network.

Review EEC and HL as separate purchasing details
The listed operating range is -40 to +70 °C. That temperature range does not establish suitability for a classified location. If the project requires location approvals, request the current certificate, device marking and installation conditions for the exact ordered version. Keep those documents with the accepted bill of materials.
What should maintenance retain?
Save the existing configuration and a clearly labelled port schedule before replacing hardware. Identify the eight copper devices, the two fiber destinations and the DC supply circuits. A ten-port count is useful for capacity planning, but the full product code is needed to preserve the specified hardware and software choices.
Request the complete EEC-HL single-mode configuration
Send HKXY the required quantity, destination, fiber endpoint information and project documentation requirements. Include the complete order code so the quotation can identify the requested configuration and separately describe any proposed alternative.
