Evaluate Cabinet Temperature and Eight-Port Ethernet Capacity with Hirschmann BRS40-00089999-TTCY99HHSESXX.X.XX BRS40 EEC Managed BOBCAT Switch
Hirschmann BRS40-00089999-TTCY99HHSESXX.X.XX identifies Type BRS40-8TX-EEC, part number 942170018, in the Hirschmann BOBCAT range. The distinguishing environmental detail of this eight-port version is its -40 to +70 °C operating range. The specified network layout remains eight 10/100/1000BASE-TX RJ45 connections in a fanless DIN rail device. It is a specific choice for projects that require the EEC range without moving to a larger port configuration or a fiber-based connection arrangement.
Use the local cabinet temperature for selection
Assess the conditions beside the switch, including heat from neighboring equipment and the expected minimum startup temperature. The extended rating does not remove the need to check ventilation, installation clearances and condensation control. Confirm the installation requirements for the supplied revision before relying on the catalog range as part of an equipment acceptance specification.

EEC does not always mean a metal housing
This exact eight-port configuration uses PC-ABS, with dimensions of 73 × 138 × 115 mm and IP30 protection. Other EEC BOBCAT versions can have different construction. Specify the actual order code and current drawing rather than transferring assumptions from a higher-port-count model. Enclosure protection should be assessed independently of the device operating temperature.
Prepare a practical network handover
Allocate the eight copper ports to local equipment, upstream connectivity and any service requirement. Record intended speeds, cable labels and the accepted settings, and retain a clear device-label photograph. The listed USB-C service interface should be used according to the applicable documentation. Keep the full EEC reference in the spare-parts record so a standard-temperature version is not supplied without review.
Enquire with HKXY
Send HKXY the exact EEC code, required quantity and delivery destination. Include cabinet temperature requirements, requested documents and accessory needs, then confirm the offered configuration and schedule in writing.
Technical reference: Belden catalog for BRS40-8TX-EEC. Confirm the current documentation and supplied revision before final engineering approval.
