Hirschmann BRS30-16042T2T-STCY99HHSESXX.X.XX All-Copper Cabinet Network Planning with Sixteen Device Ports and Four Higher-Speed Ethernet Connections
Hirschmann BRS30-16042T2T-STCY99HHSESXX.X.XX is the BRS30-20TX configuration in the Hirschmann BOBCAT range. For a network that uses copper cabling throughout, this twenty-port configuration provides sixteen 10/100BASE-TX ports and four 10/100/1000BASE-TX ports. It offers a clear ordering choice when RJ45 connectivity is required at every position and removable optical modules are outside the intended equipment scope.
Allocate capacity by port speed, not total count
A twenty-device schedule should identify the speed requirement of each connection before a switch is selected. Four ports support Gigabit operation, while the other sixteen are Fast Ethernet. Reserve the appropriate connections for the intended higher-speed links and confirm the actual endpoint capabilities during network commissioning.

Copper cabling and cabinet access
Check cable routes, connector access and the space needed to service a fully populated front panel. Record the cable destination at both ends so maintenance does not rely on memory. The device dimensions provide a housing reference, but installation drawings should also allow for plugs, terminal wiring and bend requirements.
Does twenty TX mean twenty Gigabit ports?
No. The exact port breakdown is sixteen 10/100 ports plus four 10/100/1000 ports. Retaining that distinction avoids a misleading comparison with an all-Gigabit switch. If fiber connectivity becomes a project requirement, review a different verified configuration rather than treating this copper-only variant as an SFP model.
Request the twenty-port copper configuration
For an HKXY quotation, include the complete product code, required quantity and delivery destination. Add the intended port schedule if a configuration comparison is needed, and specify required accessories or documentation as separate items on the enquiry.
