Hirschmann BRS20-16009999-STCY99HHSEAXX.X.XX: sixteen Fast Ethernet ports with expanded documented access-control and diagnostic functions
The Hirschmann BRS20-16TX-2A combines a sixteen-port Fast Ethernet hardware configuration with an expanded set of documented software functions. Its full reference is Hirschmann BRS20-16009999-STCY99HHSEAXX.X.XX, with part number 942170116. This version is a candidate when the network specification calls for functions such as DHCP snooping, Dynamic ARP Inspection or IP Source Guard alongside managed switching.
Match security functions to the network policy
The catalog lists DHCP snooping, Dynamic ARP Inspection, IP Source Guard, time-based ACLs and MACSec support for this configuration. It also includes 802.1X port-based access control, RADIUS, a TACACS+ client and local user management. These are configuration capabilities, not a promise that every connection is protected automatically. Determine which controls the network design requires, identify the supporting authentication services and apply the relevant settings during commissioning.
Inspect traffic beyond basic port status
RSPAN, SFLOW and email notification appear in the documented diagnostics, alongside port mirroring, copper cable testing and Syslog. The management list also includes an OPC-UA server. These functions give engineers additional options for collecting information and integrating switch status into their operating processes. Choose the monitoring methods that fit the site rather than enabling services without an operational purpose.
Prepare the configuration as part of the installation
Hirschmann BRS20-16009999-STCY99HHSEAXX.X.XX provides sixteen 10/100BASE-TX RJ45 ports in a fanless DIN rail package. Its standard operating range is 0 to +60 °C. Before deployment, establish management access, plan VLAN membership, preserve a configuration backup and confirm the required firmware feature availability for the supplied unit. Security functions should be evaluated with the connected devices and the site’s existing network services.

Order the 2A configuration explicitly
The BRS20-16TX and BRS20-16TX-2A share a sixteen-port description, but their published feature lists differ. Use Hirschmann BRS20-16009999-STCY99HHSEAXX.X.XX and part number 942170116 on the purchase inquiry to identify the intended version. Include any mandatory software functions in the request so that the offered configuration can be checked against the project specification.
Introduce access controls in a planned order
The functions listed for Hirschmann BRS20-16009999-STCY99HHSEAXX.X.XX support a more detailed network policy, but the deployment should follow an agreed sequence. Begin by identifying the management users, permitted management paths and authentication services used at the site. Establish and verify administrative access before applying controls that could restrict it. Record the intended VLAN assignments and the devices expected on each access port. This provides a defined starting point for evaluating 802.1X, RADIUS integration or other access-control settings in the network design.
DHCP snooping, Dynamic ARP Inspection and IP Source Guard should be considered together with the addressing plan and the behavior of connected equipment. Confirm how statically addressed devices are handled and which interfaces have infrastructure roles before applying a policy. Likewise, the presence of MACSec support in the feature list does not establish that encryption is active or that the peer configuration is compatible. Required features should be checked against the supplied software and the site configuration.
Use diagnostics to support an operational process
Additional visibility is useful when somebody is responsible for reviewing the information. Decide which events should reach the maintenance team, where logs will be retained and how monitoring data will be used. The documented diagnostics include RSPAN, SFLOW and email notification in addition to basic link monitoring, mirroring and Syslog. Select the methods that suit the available monitoring systems and define a normal baseline before the switch is handed over.
For a project inquiry, list mandatory software functions alongside Hirschmann BRS20-16009999-STCY99HHSEAXX.X.XX and part number 942170116. This is more precise than requesting a sixteen-port switch with a general security description. During acceptance, confirm the required management and diagnostic functions, preserve the configuration and record the relevant software information. That gives procurement, commissioning and maintenance teams a shared reference for the actual 2A configuration.
