Temperature, Approval Documents and Optical Module Review for Hirschmann BRS50-00122Q2Q-TTCX99HHSESXX.X.XX EEC-HL Twelve-Port BOBCAT Network Switch
Hirschmann BRS50-00122Q2Q-TTCX99HHSESXX.X.XX identifies Type BRS50-8TX/4SFP-EEC-HL, part number 942170044. The EEC-HL selection combines a -40 to +70 °C device rating with eight Gigabit copper ports and four SFP slots supporting 100/1000/2500 Mbit/s. The manufacturer record lists ISA12.12.01 under hazardous locations. That listing is a starting point for reviewing the exact supplied equipment, not a universal site-approval statement. Keep approved installation documents available to maintenance personnel alongside the final equipment list.

Request the documents that the installation needs
Compare the delivered marking, applicable certificate and installation conditions with the actual location requirements. Keep temperature and approval requirements separate in the purchase specification. Do not expand the HL suffix into an assumed ATEX rating, gas group or zone permission. Engineering approval should refer to the complete device and its documented installation conditions.
Coordinate optics with the environmental scope
Specify supported SFP modules for the intended speed and optical route. Check their temperature ratings individually, together with fiber medium, wavelength and the remote interface. The four slots are physical positions, not confirmation that four optical modules are included. Preserve the accepted module schedule with the switch order for traceable procurement.

Plan access to the compact enclosure
This EEC-HL model uses PC-ABS construction at 73 × 138 × 115 mm and has IP30 protection. Leave access to the power terminals and removable optics. Record the installed code and port allocation before replacement work, because another twelve-port BRS50 may differ in temperature or approval options even when its connectors appear identical.
