PoE Load Budgeting and Exact 2A Procurement for Hirschmann BRS52-00122Q2Q-SPCY99HHSEAXX.X.XX Twelve-Port BOBCAT Managed Industrial Ethernet Switch
Hirschmann BRS52-00122Q2Q-SPCY99HHSEAXX.X.XX identifies Type BRS52-8TX/4SFP-2A, part number 942170115. This BRS52 configuration combines eight Gigabit-capable PoE(+) copper ports with four SFP slots supporting 100/1000/2500 Mbit/s. Its 240 W PoE figure is an aggregate maximum across powered ports, not a rating available independently at every socket. Keep the 2A order selection intact when comparing quotations.
Build the power budget from the connected loads
List each powered device, its required PoE class and expected operating demand. Account for cable losses and the applicable per-port limits when reviewing the eight-port allocation. The supply reference is 48 V DC for PoE or 54 V DC for PoE+, with two inputs. Confirm the complete supply arrangement against current installation instructions.

Do not confuse input demand with enclosure heat
The catalog lists a maximum of 253 W with 240 W PoE. Much of that power is delivered onward to field devices, so the total should not simply be treated as switch heat dissipation. Use manufacturer guidance for cabinet thermal calculations and size the external power source for the specified operating conditions.
Procure data links and powered links together
Select supported optics separately for the four SFP positions, recording speed, medium and far-end compatibility. This standard-temperature version uses a 73 × 138 × 115 mm PC-ABS housing rated 0 to +60 °C. Retain the port schedule, load list and exact product code as a single commissioning and spare-parts record.
Information for configuration-specific supply
Ask HKXY for the exact 2A code, quantity and destination. Include powered-device demands, optical module references and documentation requirements so the offer can clearly separate the switch, power supply and accessories.
