Evaluate Hirschmann BRS20-1000M2M2-STCX99HHSESXX.X.XX for Ten-Port Fast Ethernet Replacements Requiring BRS20-8TX/2FX-HL Identification
When a maintenance list specifies BRS20-8TX/2FX-HL, the corresponding full ordering reference is Hirschmann BRS20-1000M2M2-STCX99HHSESXX.X.XX and the catalog part number is 942170026. The device provides eight 10/100BASE-TX copper ports and two fixed 100BASE-FX multimode SC ports. It carries a 0 to +60 °C operating specification, so it must be distinguished from the EEC-HL extended-temperature version.
Before removing the installed switch
Photograph the product label, mark the copper and fiber connections, and retain the current configuration. Confirm that the existing optical cable is multimode and that the far-end interface matches the fixed MM-SC port type. This information helps prevent a replacement choice based only on enclosure appearance or the number of connectors.

Review the HL paperwork without assumptions
The source lists ISA12.12.01 under hazardous locations. Procurement should request the applicable certificate and installation instructions, while engineering reviews their relevance to the intended location. The HL suffix is not a general permission for installation in every classified area, and it does not change the stated standard-temperature range.
Allocate room for service work
The IP30 PC-ABS device mounts on DIN rail and is listed at 8 W consumption. Plan access to the supply/signaling connection and the optical connectors around the 73 × 138 × 115 mm enclosure. Support and route the cables appropriately so ordinary cabinet servicing does not require disturbing unrelated network links.
Confirm the supply scope with HKXY
For pricing, send HKXY BRS20-1000M2M2-STCX99HHSESXX.X.XX, part 942170026, quantity and requested destination. Attach the current label, required approval documents and known firmware constraints. Identify any requested accessories explicitly and verify the quotation describes the same HL, multimode, standard-temperature configuration.
