Plan extended-temperature single-mode connectivity with Hirschmann BRS20-1000S2S2-TTCY99HHSESXX.X.XX

Hirschmann BRS20-1000S2S2-TTCY99HHSESXX.X.XX is the Hirschmann BRS20-8TX/2FX-SM-EEC BOBCAT managed DIN rail configuration with 8 10/100BASE-TX RJ45 ports and two fixed 100BASE-FX single-mode SC fiber interfaces. The catalog specifies an operating temperature range of −40 to +70 °C. Identify the unit by its complete Product code and part number 942170016 when planning an installation or requesting a repeat order. The interface arrangement, environmental values and documented software functions below define the selection more precisely than a family name alone.

Technical specifications

Documented controls and diagnostic access

The switch supports HTTPS and SSHv2 management, SNMP v1/v2/v3 and LLDP. Diagnostics include link monitoring, copper cable testing, Syslog and port mirroring. These can support a service process in which an affected port is checked against its normal state before broader configuration changes are attempted. HIPER-Ring, MRP and RSTP appear in the redundancy functions. Choose the required method as part of the complete topology and verify its operation with the participating network devices. Keep the result and the approved settings in the commissioning record.

Preserve the single-mode and EEC requirements in the same record

This ten-port configuration combines eight copper interfaces with two fixed single-mode SC optical connections. Its extended operating temperature range is a separate selection characteristic from the optical medium. Document both on the equipment schedule and verify the far-end interface and installed fiber against the relevant optical specifications. A single-mode description alone does not establish a supported distance, and an EEC label on one device does not establish the environmental rating of the whole path. Use the exact EEC mechanical and power values when preparing the cabinet design. The catalog lists 570 g device weight and 8 W consumption for this configuration. Retain space for optical cable handling as well as copper connections, and keep the full model reference visible in the maintenance record. After installation, verify the physical destinations and application communication, then preserve the accepted settings. These records help a later replacement review retain both the required optical arrangement and the original temperature selection.

Review the supply and mounting arrangement

The manufacturer lists 73 mm x 138 mm x 115 mm enclosure dimensions, 570 g device weight and 8 W power consumption. The supply specification is 2 × 12–24 V DC. Plan the cabinet layout around the DIN rail mounting arrangement, with additional clearance for the connected cables and access to terminals. IP30 is the stated enclosure protection; the surrounding installation must provide the protection required by its environment. Check the supply wiring against the manufacturer instructions and label each connection. Retain the approved power arrangement with the equipment documentation, especially where the maintenance process depends on identifying individual supply sources. Use the exact device weight when reviewing the mounting arrangement.

Keep segmentation tied to the application design

The catalog switching functions include VLANs, prioritization and IGMP snooping. Determine how these functions fit the real traffic pattern before assigning settings to individual ports. Document which connections belong to each intended network segment and where traffic must pass between equipment groups. Multicast handling should be tested with the devices that generate and receive that traffic. Save the accepted settings after application testing, and review them when port roles change. This makes the installed configuration easier to maintain than an undocumented collection of settings carried forward from another machine.

Prepare a clear replacement inquiry

Use Hirschmann BRS20-1000S2S2-TTCY99HHSESXX.X.XX and part number 942170016 as the common reference across the inquiry, quotation and acceptance record. Add the required quantity and provide the existing device label where a unit is being replaced. Describe the required network functions and connection arrangement, and identify accessories as separate supply items. Review the offered scope before release. After installation, retain the accepted configuration and record the actual cable destinations. A complete record helps future service work preserve the intended selection even when several similar switches are used at the same site.

Prepare a local service option

The catalog identifies USB-C for local management and device replacement. Configuration functions include XML-based files, automatic configuration undo and backup to a remote server when saving. Decide how service personnel will use these options if the normal management connection is unavailable. Keep the approved configuration and required access procedure with the equipment documentation. For an EEC installation, the surrounding work conditions and access to the enclosure should be considered in that service plan. Order any needed cable or adapter explicitly rather than assuming it is part of the basic switch supply. Keep a dated record of accepted configuration changes.
