Allocate Eight Powered Links and Four Additional Copper Connections with Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX BRS42 Managed Industrial Ethernet Switch
Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX identifies Type BRS42-12TX, part number 942170099. This all-copper BRS42 configuration has twelve Gigabit-capable RJ45 ports, of which eight provide PoE(+). The remaining four connections should not be counted as additional powered ports. Its 240 W PoE rating is an aggregate maximum shared across the powered interfaces, not a per-socket allowance.

Create a load schedule before selecting a supply
Record the required power class and operating demand of every powered device, then account for the applicable per-port limits and cable losses. The source specifies two supply inputs at 48 V DC for PoE or 54 V DC for PoE+. Confirm the actual power-source arrangement and wiring requirements against current manufacturer instructions rather than applying the lower-voltage specification of a non-PoE BRS model.
Separate network capacity from power capacity
All twelve copper interfaces support 10/100/1000BASE-TX, but only eight are listed as PoE(+). Reserve uplink and service connections in the same port plan as field devices. The maximum 252 W consumption includes 240 W delivered as PoE. Do not treat that entire input figure as heat released inside the switch enclosure when reviewing the cabinet thermal design.

Check the standard-temperature physical selection
The PC-ABS device is listed at 73 × 138 × 115 mm, IP30 and 0 to +60 °C. Keep the approved load list, port allocation and product identity together so later changes do not exceed the reviewed supply and installation conditions.
Request the exact configuration from HKXY
Send HKXY the full product code, required quantity, destination and accessory list. Include any installation constraints and documentation requirements so the offered configuration and delivery schedule can be confirmed before ordering.
