Confirm the installed environment before replacing an EEC switch with Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX
Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX, part number 942170090, is the Hirschmann BRS40-20TX-EEC managed industrial Ethernet switch described in the manufacturer configuration record. The EEC twenty-port copper version should be selected from the installed environment outward. Temperature range, housing, power, rail space and the configuration that must be restored all belong in the replacement comparison.
Use configuration-specific dimensions in the rail layout
The configuration record for Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX gives dimensions of Confirm from the configuration-specific manufacturer record and a weight of Confirm from the configuration-specific manufacturer record. Use those values in the rail layout instead of borrowing a drawing from a nearby BRS40 version. The device dimensions do not include connector access or cable bend space, so leave working clearance around the power terminal and all planned network connections.
The housing is listed as Metal and the protection rating as IP30. Check rail support, neighboring heat sources and the enclosure boundary as one installation review. For replacement work, compare the present width and connector arrangement before authorizing Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX; the same port count does not guarantee the same physical fit.
A replacement comparison starts with installed evidence
A replacement request for Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX should include a readable installed label, current port map, supply arrangement, enclosure conditions and saved configuration. Compare these records with catalog Type BRS40-20TX-EEC and part number 942170090. Similar BRS40 products may share a port count while differing in temperature range, housing, optical interfaces or advanced feature selection.
If an alternative is proposed, list every difference that affects physical fit, wiring, media, required software functions or commissioning. Keep the accepted comparison with the maintenance record. That turns a future repeat order into a traceable decision instead of another family-level search for Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX.

Put the switch in the panel power and heat budget
Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX is listed for 2 x 12 VDC ... 24 VDC operation, 17 W consumption and 58 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.
Convert listed security functions into site controls
The security entries for Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX include VLAN-restricted management, HTTPS certificate management, local users, privilege levels, 802.1X, RADIUS support, MAC-based port security, secure boot and signed firmware images. Availability in the feature list is not proof that a delivered unit already carries the site's access policy.
Define management identities, trusted infrastructure ports, authentication dependencies and recovery access before enabling restrictive controls. Stage changes so an administrator can verify each step and recover an approved configuration. Record the accepted policy against part number 942170090; avoid copying a neighboring model's security assumptions into the Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX file.
Close the gap between the purchase line and the delivered unit
- Confirm Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX and part number 942170090 on the offered and delivered records.
- Verify 20 Ports in total: 20x 10/100/1000BASE TX / RJ45.
- Check 2 x 12 VDC ... 24 VDC supply and the listed 17 W consumption.
- Review -40-+70 C operation, Metal 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 BRS40-00209999-TTDY99HHSESXX.X.XX.
A useful handover survives the next service visit
The handover for Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX should include the final port schedule, cable destinations, management address, software information, configuration backup and the results of required communication and recovery tests. Add the SFP list for fiber-capable versions and identify reserved ports. Store these records under the installed location and part number 942170090.
A later service team should be able to identify the correct file and understand the expected network state without reconstructing the original project. Update the record whenever an authorized endpoint, VLAN, optical module or redundancy setting changes. That discipline gives the Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX page practical value beyond the initial quotation.
Information that belongs in the quotation request
Send Hirschmann BRS40-00209999-TTDY99HHSESXX.X.XX, catalog Type BRS40-20TX-EEC, part number 942170090, 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 BRS40-00209999-TTDY99HHSESXX.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 942170090 is easier to compare than a generic search for a managed industrial Ethernet switch.
