Hirschmann BRS20-0600Z6Z6-TTCY99HHSESXX.X.XX Matching Extended-Temperature Switch Hardware and SFP Modules for DIN Rail Networks
Hirschmann BRS20-0600Z6Z6-TTCY99HHSESXX.X.XX is the BRS20-4TX/2SFP-EEC configuration of the Hirschmann BOBCAT family. The EEC switch offers an extended operating range, but that rating must also be checked for the fitted optical modules. This configuration has four copper ports and two 100 Mbit/s SFP slots for separately selected optical connections.
Use Type BRS20-4TX/2SFP-EEC together with numeric part 942170022 when comparing the supplier offer with the engineering request.
The switch and SFP must share the required environment
When preparing a complete bill of materials, include both SFPs, patch leads and the remote optical interface. Confirm approved module compatibility and the permitted temperature range of each component rather than using the switch rating for the entire link.

Electrical installation record
Catalog supply: 2 x 12 VDC ... 24 VDC; listed power consumption: 7 W. When installing the EEC SFP version, assess the operating conditions of the switch, modules and cabinet power equipment separately. Record the two supply inputs and their protection. Environmental suitability of one component does not establish suitability of the assembled network node.

Replacement acceptance checks
Check the temperature ratings of both SFPs as well as the EEC switch. Retain the module list, remote optical details and network settings before maintenance. During acceptance, confirm the physical links and required management functions, then keep the complete assembly record for the next service interval.
Can any Gigabit SFP be fitted because the physical module size is similar?
Do not assume it. These are specified as 100 Mbit/s SFP slots; the proposed module must be supported by the switch and the intended link.
Quote the switch and installation scope
Enquiry reference: Hirschmann BRS20-0600Z6Z6-TTCY99HHSESXX.X.XX; Type BRS20-4TX/2SFP-EEC; part 942170022.
Request suitable switch and module temperature grades as separate requirements. Include the intended SFPs, optical link details, quantity and destination; this allows the quotation to identify the EEC switch and any separately supplied optical components without ambiguity.
Technical reference: Belden catalog configuration for BRS20-4TX/2SFP-EEC. Confirm the current datasheet and supplied hardware revision before final engineering approval.
