Specify Temperature-Compatible Optics and Eight Copper Links with Hirschmann BRS50-00122Q2Q-TTCY99HHSESXX.X.XX EEC BOBCAT Managed Ethernet Switch
Hirschmann BRS50-00122Q2Q-TTCY99HHSESXX.X.XX identifies Type BRS50-8TX/4SFP-EEC, part number 942170020. This EEC configuration provides eight Gigabit-capable RJ45 interfaces and four 100/1000/2500 Mbit/s SFP slots across a -40 to +70 °C operating range. It retains a PC-ABS housing, an important distinction from other extended-temperature BOBCAT models that use a larger metal enclosure. Include the two 12–24 V DC supply inputs and listed 12 W consumption in the electrical review for the intended cabinet installation.

Check the complete optical assembly
Match each SFP to both the required temperature range and the switch compatibility documentation. Then check wavelength, connector, fiber type and link loss against the remote equipment. The switch rating does not extend the temperature capability of a separately selected transceiver, patch lead or power supply used in the same installation.

Fit the actual EEC version
The listed enclosure is 73 × 138 × 115 mm with IP30 protection. Use this model-specific reference for rail-space planning, while allowing cable bend and maintenance clearance. The extended operating range does not make the device a weatherproof outdoor product; enclosure protection and condensation conditions still require an independent installation review.
Prepare a practical equipment record
Assign the eight copper ports and four optical positions to named connections. Keep module references, accepted settings and device-label information with that schedule. Distinguish the required uplink speed from the capability of each attached endpoint. A complete record makes future maintenance and quotations more reliable than a family-level port-count description.
Information for configuration-specific supply
Request this exact EEC code from HKXY with quantity, destination and optical requirements. Identify the cabinet environment and required documents, then confirm the supplied switch and accessory configuration before purchasing.
