Size the PoE supply and assign twelve Gigabit ports before ordering Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX
Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX, part number 942170099, is the Hirschmann BRS42-12TX managed industrial Ethernet switch described in the manufacturer configuration record. The BRS42 record combines twelve Gigabit copper ports with PoE or PoE+ capability on eight ports. Power-source sizing, endpoint demand and ordinary data-port allocation should be completed before the switch is treated as a finished camera or field-device solution.
Put the switch in the panel power and heat budget
Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX is listed for 2 x (48 VDC (PoE)/ 54 VDC (PoE+)) operation, max. 252 W with 240W PoE consumption and max. 41 BTU (IT)/h heat output. Include these values in the protected DC supply and panel thermal calculations. If both supply inputs are used, document their source arrangement, protection and expected behavior rather than describing the switch as simply redundant-powered.
- Verify voltage at the installed terminal.
- Label both supply paths where the design uses them.
- Include switch heat in the enclosure review.
- Retain the accepted wiring and protection details with the configuration archive.
Give every copper port an intended role
The official entry for Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX records 12 Ports in total: 12x 10/100/1000BASE TX / RJ45 ; 8 x PoE(+) Ports (phantom power). Build the port schedule from actual endpoints rather than treating every connector as interchangeable capacity. Assign a device name, destination, expected rate, VLAN and service owner to each planned link. For a replacement, also record the present negotiated speed and duplex so commissioning can compare the new installation with a known baseline.
Because BRS42-12TX is an all-Gigabit BRS40 configuration, the local copper links support 10/100/1000BASE-TX. That capability does not prove that existing cables or peer devices will negotiate at 1 Gbit/s. Verify the installed channel and far-end capability, then preserve the accepted result under the full Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX record.

Map traffic paths before assigning VLANs
A switch with 12 physical interfaces can collect traffic from many controllers, operator stations and monitoring devices. Before deploying Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX, identify multicast sources, time-sensitive traffic, management traffic and any connection that carries several downstream devices. This makes VLAN, QoS, storm-protection and multicast settings responses to a documented need instead of isolated feature choices.
Review the traffic that converges on each upstream path and decide how congestion or a failed link should be observed. The BRS40 feature set provides management and diagnostic options, but the acceptance test still needs representative application communication. Save the results with part number 942170099, the final port map and the approved configuration.

Choose management paths before production connection
The management list for Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX includes HTTPS, SSHv2, SNMP, LLDP and IPv6 management, with file-transfer and local service options in the manufacturer data. Choose only the methods permitted by the site, identify who owns administrative access and decide where configuration backups and logs will be retained before connecting the switch to production.
Name each saved configuration with the complete product code, location and date. After any authorized change, update both the file and the port schedule. This makes a later restore operation specific to Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX, reducing the risk of applying a file from another BRS40 switch that appears similar but serves a different topology.
Commission against the port schedule, not only link LEDs
Start acceptance of Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX with the label, cabinet installation and DC supply. Load or prepare the approved configuration, then connect equipment according to the port schedule. Confirm link rate and duplex, test the required application exchanges and verify the selected VLAN, monitoring and redundancy behavior. A green link indicator is only one observation in that sequence.
After testing, save the final configuration and record normal port status. Identify any unused or reserved interfaces and list fitted SFP modules where applicable. The resulting handover should make part number 942170099 and the complete Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX code traceable to the actual installed network.
Close the gap between the purchase line and the delivered unit
- Confirm Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX and part number 942170099 on the offered and delivered records.
- Verify 12 Ports in total: 12x 10/100/1000BASE TX / RJ45 ; 8 x PoE(+) Ports (phantom power).
- Check 2 x (48 VDC (PoE)/ 54 VDC (PoE+)) supply and the listed max. 252 W with 240W PoE consumption.
- Review 0-+60 C operation, PC-ABS housing and IP30 protection against the cabinet.
- Test required management, security, timing and redundancy functions with the actual network.
Record exceptions before the switch enters service. Product-family similarity is not an acceptable substitute for the configuration-specific evidence associated with Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX.
Information that belongs in the quotation request
Send Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX, catalog Type BRS42-12TX, part number 942170099, quantity and delivery destination in the inquiry. State the required operating environment, management functions, security policy, timing role and redundancy design where they affect acceptance. List accessories separately so the supplier can identify the complete scope.
Ask the supplier to show the exact offered code and document revision for Hirschmann BRS42-00129999-SPCY99HHSESXX.X.XX. For replacement work, attach the installed label and summarize any function that must be retained. A configuration-specific request tied to part number 942170099 is easier to compare than a generic search for a managed industrial Ethernet switch.
