Hirschmann BRS20-08009999-STCX99HHSESXX.X.XX: Identify the BRS20-8TX-HL Copper Switch and Check its Temperature, Wiring and Approval Records
Hirschmann BRS20-8TX-HL, ordered as Hirschmann BRS20-08009999-STCX99HHSESXX.X.XX, is an eight-port managed Fast Ethernet switch with part number 942170024. Its RJ45 connections support 10/100BASE-TX, and the catalog specifies 0 to +60 °C operation. The HL configuration has an ISA12.12.01 listing; it should not be confused with the extended-temperature EEC-HL model solely because both share an HL suffix.

Is the standard temperature range sufficient?
Check the minimum startup temperature and the maximum temperature expected beside the device. A hazardous-location documentation requirement does not, by itself, determine the correct temperature option. If the cabinet conditions exceed the stated range, pause the selection and compare the appropriate configuration rather than relying on visual similarity between BOBCAT variants.

Review the installed arrangement
The fanless DIN rail design uses a PC-ABS housing and two 12–24 V DC supply inputs. The quoted 6 W consumption is useful when reviewing the enclosure power and heat budget. Retain service space around the connectors and check the mounting procedure and wiring instructions for the delivered device revision.
Keep the approval record with the equipment
Ask for the relevant certificate and device marking as part of procurement. Engineering should review the installation conditions before using the ISA12.12.01 listing in a site compliance decision. For maintenance spares, retain the complete product code in the parts system so a general eight-port switch is not substituted without that review.
Request a configuration-specific HKXY quotation
HKXY enquiries should include BRS20-08009999-STCX99HHSESXX.X.XX, 942170024, quantity and destination. For an installed-base replacement, add the current device label, required certificate documents and firmware or configuration restrictions. Agree the supplied version and delivery terms before the purchase order is released.
