Hirschmann BRS20-1000M2M2-TTCX99HHSESXX.X.XX Selection Notes for Extended-Temperature BOBCAT Networks and Multimode Fiber Approval Review
Hirschmann BRS20-1000M2M2-TTCX99HHSESXX.X.XX is the ordering reference for BRS20-8TX/2FX-EEC-HL, part number 942170037. This managed BOBCAT switch combines eight RJ45 Fast Ethernet ports, two fixed multimode SC optical ports, and a -40 to +70 °C operating range. The original manufacturer record also lists ISA12.12.01 for the HL configuration; review that documentation independently from the network connection design.

Define the installation before choosing the variant
A specification for this switch should identify the required environmental range, the site documentation requirements and the fiber interface together. A standard-temperature version or a model with single-mode optics is not an automatic substitute. The complete code prevents those differences from being lost when several BOBCAT variants appear similar in a parts list.

What belongs in the optical assessment?
Both fiber ports are fixed 100BASE-FX MM-SC interfaces. Confirm multimode cable type, far-end equipment and the loss introduced by patch panels and splices. Preserve connector cleanliness during installation and follow the equipment instructions. Neither a long fiber route nor the presence of an SC connector by itself establishes compatibility with this configuration.
Keep the approval boundary explicit
The hazardous-location listing is ISA12.12.01. Obtain the applicable certificate and installation conditions for engineering review; this description does not assign an ATEX category, site zone or gas group. Compare the delivered label with the ordered configuration and retain the supporting documents with the equipment maintenance record.
Information for your HKXY enquiry
Include BRS20-1000M2M2-TTCX99HHSESXX.X.XX, part 942170037, quantity, destination and required certificate documents in your HKXY enquiry. For a replacement, add the old label and fiber-route information. Confirm delivery scope and scheduling for this specific EEC-HL version before purchase.
