Combine copper device connections and fiber uplinks with Hirschmann BRS20-2000ZZZZ-STCY99HHSESXX.X.XX
Hirschmann BRS20-2000ZZZZ-STCY99HHSESXX.X.XX is the Hirschmann BRS20-16TX/4SFP managed industrial switch, part number 942170055. This configuration provides twenty network ports in total: sixteen 10/100BASE-TX RJ45 connections and four 100 Mbit/s SFP slots. It suits network designs that need copper connections at the equipment level together with fiber connections between network locations.
Select fiber interfaces around the actual link
The four SFP slots are arranged in two uplink groups with two slots in each group. The specified slot rate is 100 Mbit/s. Choose compatible transceivers according to the fiber type, optical wavelength, connector and link budget required by the installation. An SFP slot alone does not define the transmission distance. Include the selected optical modules in the inquiry when they are required, so that the supply scope can be confirmed.
Keep the copper and uplink port roles clear
A port schedule helps distinguish the sixteen RJ45 device connections from the four fiber connections. Consider how traffic from the copper ports will share the uplinks, and identify the intended redundancy arrangement before commissioning. VLANs, QoS, IGMP snooping and ingress storm protection are listed in the switching functions. HIPER-Ring, MRP and RSTP are available among the documented redundancy options, subject to the topology and configuration used.

Commission and service the switch locally or over the network
Hirschmann BRS20-2000ZZZZ-STCY99HHSESXX.X.XX supports HTTPS, SSHv2 and SNMP management, with USB-C listed for local management and device replacement. Port mirroring, cable testing, link speed monitoring and Syslog support network diagnostics. Preserve a configuration backup and record the optical module identities alongside the switch’s management settings; both are relevant when restoring a fiber-connected installation after maintenance.
Allow for power, enclosure space and optical modules
The fanless DIN rail unit has a PC-ABS housing, IP30 protection and a 0 to +60 °C operating range. Its listed power consumption is 15 W. Dimensions are 109 × 138 × 115 mm and weight is 950 g. Specify Hirschmann BRS20-2000ZZZZ-STCY99HHSESXX.X.XX, part number 942170055, quantity and required SFP modules when requesting a quotation. This identifies the mixed copper/fiber version rather than a sixteen-port copper-only switch.
Define the optical link before selecting the transceiver
A fiber connection depends on more than the presence of an SFP slot. For each link, identify the far-end interface, fiber type, connector arrangement and the optical requirements of both ends. Review the optical budget for the installed path, including intermediate connections, when choosing a compatible module. The switch specification identifies four 100 Mbit/s SFP slots; it does not assign a universal transmission distance to those slots. Keep the switch order code and the optical module references as separate entries in the equipment schedule.
This approach is especially useful when Hirschmann BRS20-2000ZZZZ-STCY99HHSESXX.X.XX connects local copper devices to another cabinet. The sixteen RJ45 connections and the fiber uplinks serve different roles in the port plan. Record which uplink leads to each network location and how traffic will be distributed over the available connections. The two groups of SFP slots should be identified clearly in the drawing so that installation and maintenance teams can trace the intended paths.
A handover record for mixed copper and fiber networks
At acceptance, retain the switch configuration, port schedule and optical module list together. For the copper connections, record normal link speed and duplex status. For the fiber paths, record the far-end equipment and the approved module reference at each end. Labeling the patch leads and documenting their destinations helps the service team distinguish a cabling issue from a configuration change. When redundant paths are used, include a controlled test of the selected redundancy method in the commissioning plan.
When requesting Hirschmann BRS20-2000ZZZZ-STCY99HHSESXX.X.XX, state whether the quotation should include the required SFP modules and any related installation accessories. Confirm the quantity of each module type rather than assuming that every slot must use the same optical interface. A clear supply schedule links the twenty-port switch configuration to the actual network design and makes comparisons between offers more meaningful.
