Metal-Enclosure Fit, PoE Power and Optical Temperature Checks for Hirschmann BRS52-00122Q2Q-TPDY99HHSESXX.X.XX EEC Twelve-Port BOBCAT Managed Switch
Hirschmann BRS52-00122Q2Q-TPDY99HHSESXX.X.XX identifies Type BRS52-8TX/4SFP-EEC, part number 942170049. The EEC BRS52 provides eight Gigabit-capable PoE(+) copper connections and four 100/1000/2500 Mbit/s SFP slots in a metal housing. Its -40 to +70 °C operating range and 240 W aggregate PoE limit must be considered alongside the actual loads, optical modules and cabinet arrangement.

Allow for the metal-version installation envelope
This model measures 123 × 140 × 115 mm, unlike the smaller PC-ABS standard-temperature version. Check the current drawing against rail space, terminal access and cable routing. IP30 protection does not establish suitability for unprotected outdoor use. Review the surrounding enclosure, condensation conditions and installation instructions before approving the physical arrangement.

Specify the supply and PoE allocation
The device lists two 48 V DC inputs for PoE or 54 V DC inputs for PoE+. Calculate the combined powered-device demand against the 240 W aggregate allowance and check per-port requirements. The maximum 253 W consumption includes delivered PoE power; it is not a statement that the switch releases that entire amount as cabinet heat.
Keep the optical route within its own ratings
Select compatible SFP modules for each intended speed and confirm their temperature limits. Match wavelength, fiber type and link loss to the remote interface. An EEC switch does not upgrade the environmental rating of every connected accessory. Preserve the final load and module schedules with the exact device code for future replacements.
Your purchase enquiry
Provide HKXY with the EEC reference, quantity, destination and required PoE load schedule. Add SFP requirements and cabinet constraints, then confirm power supplies, modules and documents as separate quotation items.
