Review Hirschmann BRS40-00129999-TTCY99HHSESXX.X.XX for BRS40-12TX-EEC Applications Requiring All-Gigabit Copper Ports and -40 to +70 °C Operation
Hirschmann BRS40-00129999-TTCY99HHSESXX.X.XX corresponds to Hirschmann BRS40-12TX-EEC, part 942170078. The twelve RJ45 ports all support 10/100/1000BASE-TX, and the EEC device operating range is -40 to +70 °C. This combination is useful to assess when an industrial cabinet requires Gigabit-capable copper connections and operating conditions outside the standard-temperature BRS40-12TX range.

Temperature selection should follow the enclosure review
Consider cold startup and the hottest expected operating period near the switch. Nearby power equipment can affect the local temperature inside an otherwise acceptable room. The extended range does not establish protection against rain, condensation or dust exposure. Review the PC-ABS IP30 housing as part of the complete enclosure arrangement and installation instructions.

Make the copper-only scope clear
This twelve-port configuration has no SFP slots in its listed port arrangement. Plan copper routes and confirm the required connection speed at each endpoint. The manufacturer provides a 0–100 m twisted-pair segment reference; evaluate cable condition and termination as part of commissioning. If a route requires optical media, select the appropriate interface configuration.
A maintenance spare needs more than an EEC label
Preserve the current port schedule and approved management configuration. Compare the full ordering code, supply requirements and installation space before accepting a replacement. The source lists 11 W consumption, two 12–24 V DC inputs and a 73 mm-wide housing. Those figures provide a practical cabinet reference while the delivered instructions govern the actual installation.
Ordering information for HKXY
Contact HKXY with BRS40-00129999-TTCY99HHSESXX.X.XX, part 942170078, quantity and destination. State the EEC temperature requirement and include existing label details for replacements. Confirm the supplied preset, required accessories, documentation and delivery schedule rather than relying on a generic twelve-port switch description.
