Separate Copper Device Capacity from Optical Module Selection with Hirschmann BRS40-0024OOOO-STCY99HHSESXX.X.XX Twenty-Four-Port BOBCAT Ethernet Switch
Hirschmann BRS40-0024OOOO-STCY99HHSESXX.X.XX identifies Type BRS40-20TX/4SFP, part number 942170067, in the Hirschmann BOBCAT range. Twenty copper Gigabit-capable ports and four SFP positions form this twenty-four-port managed switch. It provides a clear hardware basis for a cabinet with many local Ethernet devices and separately designed optical links. The SFP interfaces are specified at 100/1000 Mbit/s, so the transceiver schedule remains an important part of both the network design and the purchase request.

Account for modules as well as the switch
List each required SFP by supported model, operating speed, fiber type and optical characteristics. Include the remote interface and the expected route loss when the module has not yet been selected. The switch code defines four slots, but it does not establish which transceivers are included in a supplier offer or the reach of every possible fiber connection.

A high port count needs clear service records
Assign cable labels and network destinations before the cabinet becomes fully populated. Retain a port map that distinguishes the twenty RJ45 positions from the four optical connections. Where maintenance spares are required, record the accepted switch configuration and optical module references together; a general twenty-four-port description leaves too much ambiguity for later procurement.
Review the cabinet operating conditions
The manufacturer record lists 19 W consumption and a 0 to +60 °C operating range for this PC-ABS version. Check the temperature beside the switch and allow access to connectors and modules. The stated housing dimensions are a starting point for rail-space planning, not a substitute for the installation drawing or the cable-clearance requirements of the finished cabinet.
Information for your purchase request
Ask HKXY to quote the exact code, required quantity and four-position optical scope. State destination, documentation needs and requested schedule, and confirm separately whether modules and other accessories are included.
