Select and Allocate Eight Gigabit-Capable Copper Connections with Hirschmann BRS40-00089999-STCY99HHSESXX.X.XX BRS40 Compact BOBCAT Managed Switch
Hirschmann BRS40-00089999-STCY99HHSESXX.X.XX identifies Type BRS40-8TX, part number 942170008, in the Hirschmann BOBCAT range. For a smaller copper-based machine network, this configuration provides eight 10/100/1000BASE-TX RJ45 ports in a fanless DIN rail device. Its 73 mm-wide PC-ABS housing offers a compact starting point for cabinet planning. Unlike a mixed-speed BRS30 arrangement, all eight copper connections in this particular BRS40 selection are Gigabit-capable, subject to the connected equipment and cabling.

Include the upstream connection in the eight-port plan
List the required controllers, operator interfaces and other Ethernet devices, then include the connection to the surrounding network. An upstream link uses one of the same eight sockets. Leave deliberate allowance for commissioning or expansion where needed, rather than approving the switch from an endpoint count that omits inter-switch connections and temporary service access.
What is included in the hardware reference?
The source lists two 12–24 V DC supply inputs, 8 W consumption and USB-C for local management and device replacement. Review terminal assignments and the documented service procedure for the delivered revision before wiring or commissioning. A supported management interface does not mean that every cable, adapter or configuration accessory is included with an individual supplier offer.

A compact housing still needs an installation envelope
The enclosure dimensions are 73 × 138 × 115 mm, with IP30 protection and a 0 to +60 °C operating range. Check cable bending, terminal access and the conditions inside the cabinet as well as the bare footprint. For maintenance work, keep the existing device label, approved settings and port assignments available for comparison with the proposed replacement.
Configuration-specific quotation
