Hirschmann BRS20-0600M2M2-STCY99HHSESXX.X.XX Mixed Copper and Multimode Fiber Network Planning for a Six-Port BOBCAT Switch
Hirschmann BRS20-0600M2M2-STCY99HHSESXX.X.XX is the BRS20-4TX/2FX configuration of the Hirschmann BOBCAT family. The four copper ports can connect nearby Ethernet devices while two fixed multimode fiber ports provide links to other network locations. This configuration is useful to assess when the existing optical cabling uses SC connectors and 100BASE-FX interfaces.

Local copper connections with fixed multimode uplinks
Identify the fiber core size and the specification of the far-end optical interface. Connector fit does not confirm an optical match: wavelength, transmit level, receiver limits and link loss must be checked together.

Cabinet supply planning
- Catalog supply: 2 x 12 VDC ... 24 VDC; listed power consumption: 7 W.
- A mixed copper and fiber cabinet still needs a separately planned DC supply. Record the two input connections, the upstream protective circuits and accessible isolation points. Include the switch consumption in the cabinet calculation together with the other installed communication equipment.

Replacement acceptance checks
- Separate the four local copper connections from the two multimode fiber links on the drawing.
- Label each SC connection and record the model at the opposite end of the fiber.
- Verify the optical links and controller communications following commissioning, using the accepted project configuration.
Are these two optical ports SFP slots?
No. The selected code describes two fixed 100BASE-FX multimode SC interfaces. A switch requiring removable SFP modules is a different order configuration.
