Copper Port Capacity, Cabling and Service Access Planning for Hirschmann BRS40-00249999-STCY99HHSESXX.X.XX Twenty-Four-Port BOBCAT Managed Switch
Hirschmann BRS40-00249999-STCY99HHSESXX.X.XX identifies Type BRS40-24TX, part number 942170091, in the Hirschmann BOBCAT range. This twenty-four-port configuration uses RJ45 connections throughout, with every port supporting 10/100/1000BASE-TX. It is a copper-only selection rather than a twenty-copper-port model with four SFP positions. That distinction should be explicit in the equipment list, especially when different twenty-four-port BOBCAT configurations are being compared for the same industrial cabinet or replacement request.
Reserve capacity using a complete connection schedule
List every endpoint and inter-switch connection that will occupy a physical socket. Decide whether service access or planned expansion requires spare ports. The twenty-four-port count does not mean twenty-four devices can be connected while ignoring upstream links. Keep the accepted allocation with the network drawing so later additions can be assessed against actual available capacity.

Prepare the copper installation for its intended speed
Gigabit-capable interfaces must be matched with suitable cabling and endpoint capabilities. The manufacturer lists a 0–100 m twisted-pair segment reference. Review the cable route, termination and site testing requirements instead of treating interface speed as a guarantee of end-to-end application performance. If a link needs fiber, select an appropriate optical configuration rather than ordering an SFP for this copper-only device.
Make a dense cabinet maintainable
The PC-ABS housing is listed at 109 × 138 × 115 mm and mounts on DIN rail. Plan additional room for cable routing, terminal access and removal of individual plugs. Check the 19 W consumption and 0 to +60 °C operating range within the complete enclosure design. Keep an accessible port map and retained configuration for maintenance personnel.
Information for your purchase request
Provide HKXY with the exact twenty-four-copper-port code, quantity, destination and target delivery date. For a replacement, attach a device-label photograph and any configuration or documentation requirements that the offered unit must preserve.
