Hirschmann BRS30-1604OOOO-STCY99HHSESXX.X.XX Copper Device Expansion and Removable Fiber Uplink Planning for a Twenty-Port Industrial Managed Switch
Hirschmann BRS30-1604OOOO-STCY99HHSESXX.X.XX is the BRS30-16TX/4SFP configuration in the Hirschmann BOBCAT range. Sixteen Fast Ethernet copper ports can serve local devices while four SFP slots provide separately selected 100/1000 Mbit/s optical connections. This twenty-port BRS30 selection suits an enquiry where the number of copper devices is known but the fiber modules still need to be specified for each route.
Specify the optics as an explicit line item
For each SFP position, identify the supported module, fiber type, wavelength, connector and far-end interface. The switch slot rating does not state the reach of an installed optical link. Ask the supplier to identify which modules are included, which are excluded and which require separate confirmation before ordering.

Sixteen copper ports remain Fast Ethernet
The copper connections are 10/100BASE-TX; only the optical slot specification includes 1000 Mbit/s. Document this distinction when comparing the device with an all-Gigabit switch. A higher-speed uplink can serve a different network role, but it does not change the physical rate of the connected copper ports.
Reserve service space in a populated cabinet
Cable access matters when sixteen RJ45 ports and four optical positions are used together. Plan patch lead routes, connector access and module removal space without relying solely on the bare housing dimensions. Keep supply wiring and the approved port map accessible to the people who will maintain the installation.
Request the switch and a clearly defined optical scope
Supply HKXY with the full switch code, required quantity and a four-position SFP schedule. If the modules are not yet selected, include fiber route details and remote equipment references so those open items can be identified in the quotation.
